Answers

Answer 1

The magnitude of the force needed to supply 100 N m of torque to the bolt is 417 N

Here r = < 0, 0.3, 0 >

F = F < 0, 3, -4 >

T = r F sin θ

If v = < 0, 3, -4 >, θ is the angle between r and v

r . v = r v cos θ

0.9 = ( 0.3 ) ( 5 ) cos θ

Cos θ = 0.6

Sin θ = 0.8

T= r F sin θ

100 = 0.3 F ( 0.8 )

F = 417 N

Torque is a type of force which causes an object to rotate about an axis. Torque is represented as τ. Its unit is N m

Therefore, the magnitude of the force needed to supply 100 N m of torque to the bolt is 417 N

A car travels up a hill at a constant speed of 33 km/h and returns down the hill at a constant speed of 72 km/h. calculate the average speed for the round trip.

Answers

The average speed for the round trip is 90.51 km/hr when a car travels up a hill at a constant speed of 33 km/h and returns down the hill at a constant speed of 72 km/h.

To find the average speed for the round trip, the given values are,

constant speed v₁ = 33 km/hr

constant speed v₂ = 72 km/hr

What is average speed?The average speed of the car is defined as the ratio of the total distance travelled  by the car to the total time taken by the car.

         Average speed = total distance traveled / total time taken

Let d is the total distance traveled by the car.

Thus , distance traveled in each journey is d/2.

So, the time taken for going up the hill  is t₁ = (d/2) / v₁

= (d/2) / 33

= d / 66

Next, the time taken for going down the hill is t₂ = ( d/2 ) / v₂

= ( d/2) / 72

= d / 144

Thus, average speed is v avg = 2d / ( t₁ + t₂ )

= 2d / ( ( d/66)+(d/144))

= 2d / (210d / 9504)

= 2d / 0.0220959

= 90.51 km/hr.

The average speed of the round trip is 90.51 km/hr.

upiter has a mass of approximately . jupiter’s moon ganymede has a mass of approximately and it orbits jupiter at a distance of approximately . calculate the approximate magnitude of the attractive gravitational force between ganymede and jupiter.

Answers

The approximate magnitude of the attractive gravitational force between ganymede and jupiter  is 16.35 x 10^21 N .

According to Newton’s Law of Gravitation, the gravitational force between two bodies is directly proportional to the masses of the two objects and is inversely proportional to the square of the distance between them.

The above statement can be represented by the following equation:

F = Gx (m1)x (m2)/r^2

Here G = Universal Gravitational Constant = 6.67 x 10^-11 N m^2/kg^2

m1 and m2 are the masses of two bodies

r is the distance between the bodies

Putting m1= Mass of Jupiter= 1.89 x 10^27 kg

m2 =Mass of Ganymede 1.48 x 10^23 kg

r = Distance between Jupiter and Ganymede = 1.07 x 10^9 meters

F = 6.67 x 10^-11 x 1.89 x 10^27 x 1.48 x 10^23/(1.07 x 10^9)^2

On solving the above equation F comes out to be 16.35 x 10^21 N.

Thus, the approximate magnitude of the gravitational force between Ganymede and Jupiter is 16.35 x 10^21 N.

What is gravitational force?

Because it consistently attempts to pull masses together rather than pushing them apart, the gravitational force is known as attractive. In actuality, every thing in the cosmos, including you, is pulling on every other object.

Gravitation is the force in physics that draws two masses together. Unbelievably, every single particle of matter in the cosmos attracts every other particle through gravity.

Answers

The asthenosphere is an important layer because it responds to forces by flowing as it is relatively weak.

This is because the asthenosphere is solid, but mobile, meanwhile the lithosphere is solid and relatively rigid.

What is asthenosphere?

The Earth's upper mantle contains an area known as the asthenosphere, which is ductile and mechanically fragile. Between 80 and 200 km (50 and 120 mi) below the surface, it is located beneath the lithosphere, and it can reach a depth of 700 km (430 mi). It is difficult to determine the asthenosphere's lower border, though.

Despite the asthenosphere being almost completely solid, its mechanical weakness is caused by a tiny quantity of rock melting (less than 0.1% of the rock). This is the primary source of magma on Earth because as it wells higher, more extensive decompression melting of the asthenosphere occurs.

It is where some magmas that erupted above subduction zones or in areas of continental rifting, as well as mid-ocean ridge basalt (MORB), originated.

What is the distance traveled by the red ball between 12s and 24

Answers

The distance the red ball travelled between 12 s and 24 s is 2116.8 m

What is free fall?

Free fall is motion under gravity.

What is the distance traveled by the red ball between 12s and 24

If we assume the red ball is falling freely, it has an initial velocity of zero.

Using the equation of motion s = ut - 1/2gt², we find the distance it travels or height it drops after the given time. where

u = initial velocity = 0 m/s, t = time and g = accleration due to gravity = 9.8 m/s²

So, s = ut - 1/2gt²

s = 0 × t - 1/2gt²

s = -1/2gt²

Distance the red ball fall in 12 s.

Since the distance the red ball falls is s = -1/2gt² with t = 12 s, we have

s = -1/2gt²

= -1/2 × 9.8 m/s² × (12 s)²

= -1/2 × 9.8 m/s² × 144 s²

= -4.9 m/s² × 144 s²

= -705.6 m

Distance the red ball fall in 24 s.

Since the distance the red ball falls is s = -1/2gt² with t = 24 s, we have

s' = -1/2gt²

= -1/2 × 9.8 m/s² × (24 s)²

= -1/2 × 9.8 m/s² × 576 s²

= -4.9 m/s² × 576 s²

= -2822.4 m

So, the distance the red ball travelled between 12 s and 24 s is d = s' - s

= -2822.4 m - (-705.6 m)

= -2822.4 m + 705.6 m

= -2116.8 m

So, the distance the red ball travelled between 12 s and 24 s is 2116.8 m

The magnitude of the resultant is

[tex]\|\hat R\| = \sqrt{(2.00\,\mathrm m)^2 + (-5.20\,\mathrm m)^2} \approx \boxed{5.57\,\mathrm m}[/tex]

The direction or angle the resultant makes with the positive horizontal axis is [tex]\theta[/tex] such that

[tex]\tan(\theta) \approx \dfrac{-5.20\,\mathrm m}{2.00\,\mathrm m} \approx -2.60[/tex]

Note the signs of the [tex]\hat\imath[/tex] and [tex]\hat\jmath[/tex] components of [tex]\hat R[/tex]. They tell us that [tex]\hat R[/tex] points into the fourth quadrant, and this means we can take the inverse tangent of both sides without any extra steps*. We then get

[tex]\theta \approx \tan^{-1}(-2.60) \approx \boxed{-67.0^\circ}[/tex]

* There would have been an extra step if [tex]\hat R[/tex] were pointing into either the second (negative [tex]\hat\imath[/tex], positive [tex]\hat\jmath[/tex]) or third quadrant (both negative [tex]\hat\imath[/tex] and [tex]\hat\jmath[/tex]). The inverse tangent function has a range of -90° to 90°, which means upon taking the inverse tangent of both sides of

[tex]\tan(\theta) = \dfrac{R_y}{R_x} \implies \theta = \tan^{-1}\left(\dfrac{R_y}{R_x}\right)[/tex]

we would only recover some angle [tex]\theta[/tex] between -90° and 90°. Yet our resultant must have some angle between -180° and -90°, or between +90° and +180° to belong to quadrant II or III. To get around this, we add an appropriately chosen multiple of 180° to the right side after taking the inverse tangent.

y = 4 x sin (170°) = 4 x 0.76604444311 = 3.06

In cartesian form → ( 2.57 i + 3.06 j )

c)r = 20 inches , θ = 210°

x = 20 x cos (210°) = 20 x -0.86602540378 = -17.32

y = 20 x sin (210°) = 20 x -0.5= -10

In cartesian form → ( -17.32 i - 10 j )

Therefore, in cartesian coordinates, we can write the position vectors as -

a) → r = 12.4 m , θ = 170°    ↔     - 12.21 i + 2.15 j

b) → r = 4 cm , θ = 50°   ↔    2.57 i + 3.06 j

on which date will the sun’s altitude be highest for an observer at 23 degrees north latitude? on which date will the sun’s altitude be highest for an observer at 23 degrees north latitude? march 21 june 21 september 21 december 21

Answers

On June 21 the sun’s altitude will be highest for an observer at 23 degrees north latitude.

What is special on June 21?

In the Northern Hemisphere, June 21 is both the longest day and the shortest night of the year. Here summer solstice occurs.

It is during this time that the Northern Hemisphere is closest to the Sun, and the Sun shines directly overhead on the Tropic of Cancer (23.5° North). North and south of the equator, the Tropics of Cancer and Capricorn, respectively, are located at latitudes of 23.5°.

At 5:14 a.m. Eastern time, the summer solstice occurs in 2022. As far north as the sun ever shines in the sky, it is exactly overhead the Tropic of Cancer at this particular moment.

The June solstice depends on the moment the Sun crosses its northernmost point from the celestial equator, not on any particular day or time on the calendar.

What did you include in your response? check all that apply. the law of conservation of momentum is satisfied. the momentum before the collision is 1.5 kg • . the momentum after the collision is 1.5 kg • . the momentum is the same after the collision as it was before the collision.

Answers

After a collision, there is no change in the momentum from the initial situation. This statement  satisfies the law of conservation of momentum. Hence, Option D is correct.

What is the law of conservation of Momentum?

Momentum is the sum of an object's mass and velocity, and it is a property of all moving objects. This can be expressed mathematically as p=MV, where p stands for momentum. The momentum of an object can fluctuate because its velocity can. When describing the momentum of a system of objects, the Law of Conservation of Momentum is helpful. The Law of Conservation of Momentum, in its most basic form, states that the total momentum of an isolated system stays constant.

Hence, the momentum will be the same after the collision as it was before the collision.

Graph representing a linear relationship between mass on the x-axis and kinetic energy on the y-axis D. Graph representing a relationship between mass on the x-axis and kinetic energy on the y-axis. the line starts at the origin and increases as it goes with a small bend

Answers

The graph representing a linear relationship between mass [m] on the x-axis and kinetic energy (E[k]) on the y-axis is the correct graph.

What is Mechanical Energy ?

Mechanical energy is the energy of either an object in motion or the energy that is stored in objects by their position. Mechanical energy is the sum of Kinetic and Potential Energy. Mathematically -

E [M] = E [K] + E [P]

Given is a set of statements that represents the relationship between mass and Kinetic energy of the body.

The Kinetic energy of the body is the energy of the body by virtue of its motion. Consider a body of mass 'm' moving with velocity 'v' in a straight line. The Kinetic energy of the body will be -

E [K] = 1/2 mv²

If we assume that the velocity remains constant, than the value of 1/2 v² will become constant (say A). Then, the equation can be written as -

E [K] = A × m    ... Eq. 1

The general equation of a straight line representing a linear equation whose y - intercept is 0 is -

y = mx     ... Eq. 2

Comparing Eq. 1 and Eq. 2, we get -

y = E [K]   {Kinetic energy}

m = A    {slope of line}

x = m    {mass}

For A = 1

E [K] = m

E [K] [tex]\alpha[/tex] m

The graph will be linear in relationship with Kinetic energy along y - axis and mass along the x - axis. The graph is attached with the answer.

Therefore, the graph representing a linear relationship between mass [m] on the x-axis and kinetic energy (E[k]) on the y-axis is the correct graph.

For this assignment, consider the fact that our country spends millions of dollars each year to explore space and to learn about the structure and composition of the universe. Why do you think learning about space is a priority for our country and why are we willing to spend so much money on it? Create a discussion post about your thoughts on space exploration, including why or why not you think space exploration should be a national priority and what you think scientists hope to learn by continuing to explore the makeup of the universe.

Answers

I think that our nation's leaders prioritize space education because they see the potential benefits for us in the future.

The phrase "space exploration" is used to describe any activities connected to the study of space. Space exploration has generally been one of the subjects that mankind have been interested in. However, fresh discoveries have been made in recent years as a result of technological advancements.The majority of people on Earth are interested in space exploration because we think we fully understand the Earth's space and we want to go beyond what is possible. But the question is: Should space exploration be a top priority for the country?Space exploration shouldn't, in my opinion, be a top priority for our government since the millions of money spent on it may be better spent on enhancing the lives of many people here on Earth and abroad.I don't mean to imply that space exploration is a topic that doesn't merit consideration and investigation. However, I do think that it shouldn't be a top priority. Instead of looking for life on other planets and potentially habitable spaces when we already have our place in the universe, we should consider that our reality is on Earth and use those resources to protect it from the environmental damage we have caused it.
