the football team at enormous state university (esu) uses vector displacements to record its plays, with the origin taken to be the position of the ball before the play starts. in a certain pass play, the receiver starts at 1.0i^−5.0j^, where the units are yards, i^ is to the right, and j^ is downfield. subsequent displacements of the receiver are 7.0i^ (he is in motion before the snap), 8.0j^ (breaks downfield), −7.0i^ 3.0j^ (zigs), and 11.0i^ 12.0j^ (zags). meanwhile, the quarterback has dropped straight back to a position −7.0j^.

It is correct to state that if the human race continues to use energy as it currently does, without change, we will see negative environmental impacts all over the world in this century.

Global warming is the heating of the Earth's surface seen since the pre-industrial period because of human activities, mainly the combustion of fossil fuels, which boosts heat-trapping greenhouse gas levels in the Earth's atmosphere.

As an example, vehicles that run on fossil fuels, such as cars and buses, emit polluting gases into the atmosphere, causing the greenhouse effect and contributing to global warming.

To address these issues, it is necessary to raise public awareness so that there is a growing interest in and search for environmentally responsible solutions, such as mass production of electric cars that do not pollute the environment.

It is right to argue that if the human race persists to use power in the same manner that it as of now does, we will see negative environmental impacts all over the world in this century.

Answer: its B hence "An object with a higher mass has more inertia which causes it to speed up less quickly."

Explanation: i took the test

You can move in some direction to reduce this distance to zero if the body remains at rest position.

The distance can be zero when the object is present at rest position. Distance is defined as the length covered by a body. The distance can also be defined as the length of the path between two points. Displacement and distance are used for the measurement of length covered by a body. There is one difference between distance and displacement which is displacement can be zero but distance cannot be zero until it stops moving because distance is the total path covered by a body but displacement is the shortest distance between two points. If the distance is not covered by a body means the body can't move then the distance will  be zero.

So we can conclude that You can move in some direction to reduce this distance to zero if the body remains at rest position.

The distance has the proton been deflected sideways when it reaches the far edge of the capacitor is [tex]1.08 * 10^-3[/tex].

What is parallel-Plate Capacitor:

When two parallel plates are connected across a battery, the plates are charged and an electric field is established between them, and this setup is known as the parallel plate capacitor.

The parallel plate capacitor formula is given by:

C = k∈0 A / d.

Now,

The electric field is, E = sigma/epsilon_{o} = (1 * 10 ^ - 6)/(8.85 * 10 ^ - 12) = 1.129 * 10 ^ 5 * N / C

The force on the proton is (F) = q E = 1.6 * 10 ^ - 19 * 1.129 * 10 ^ 3 = 1.81 * 10 ^ - 14 * N

So, the acceleration of the proton is,

a = F/m = (1.81 * 10 ^ - 14)/(1.67 * 10 ^ - 27) = 1.084 * 10 ^ 13 * m / (s ^ 2)

Time taken to cross the plate is (t) = d/u = (2.4 * 10 ^ - 2)/(1.7 * 10 ^ 6) = 1.41 * 10 ^ - 8

Therefore, the required distance travelled distance is,

d = u t + 1/2 * a * t ^ 2

d = 0 + 1/2 * 1.084 * 10 ^ 13 * (1.41 * 10 ^ - 4) ^ 2

d = 1.08 * 10 ^ - 3 * m

Therefore, the distance is 1.08*10^-3 m

A parallel-plate capacitor has 2.4 cm × 2.4 cm electrodes with surface charge densities ±1.0×10^−6C/m2. A proton traveling parallel to the electrodes at 1.4×10^6 m/s enters the center of the gap between them.

It is true that as soon as the marble is launched out of the cannon it is in the free fall (provided that there is no air resistance). The value of acceleration will be -10 m/s² for upward motion and 10m/s² for downward motion.

Free fall is defined as the condition in which the body moves under the influence of gravity alone. In the case of free fall, there is no air resistance.

Given in the question is a marble launched out of cannon.

Yes, as soon as the marble is launched out of the cannon it is in the free fall (provided that there is no air resistance) since it moves under the influence of gravity only. As soon as the marble is launched out of the cannon, it will follow a parabolic path. Now, it will move upwards and reach maximum height. From the launch to the maximum height, the marble will move opposite to that of gravity and hence the value of acceleration due to gravity will be g = - 10 m/s². After the maximum height is achieved, it starts to descend towards the ground such that the velocity vector and acceleration vector are both directed in the same direction. In this case, the acceleration due to gravity will be g = 10 m/s²

Therefore, it is true that as soon as the marble is launched out of the cannon it is in the free fall (provided that there is no air resistance). The value of acceleration will be -10 m/s² for upward motion and 10m/s² for downward motion.

The radius of Earth to have the same mass density as matter in a nucleus is 1.80 x 10^3 m.

The density of a body is given by the following expression;

Density = Mass/Volume

Let the radius of Earth be r.

As the earth is a sphere, hence its volume will be 4/3 x π x r^3

So, the equation becomes

Density = Mass/(4/3 x π x r^3)

The mass of the earth is given as 5.98 x 10^24 kg and the density of the nucleus is given to be 2.4 x 10^14 m.

2.4 x 10^14 = 5.98 x 10^24/ (4/3 x 3.14 x r^3)

On Solving the above equation, the radius r comes out to be

The stopping distance s from an initial speed of 80 mi∕hr will be 219 ft.

Here we can define the value t = 0s as the moment when the car starts decelerating.

At this point, the acceleration of the car is given by the equation:

A(t) = -10 ft/s^2

Where the negative sign is because the car is decelerating.

To get the velocity equation of the car, we integrate over time, to get:

V(t) = (-10 ft/s^2)*t + V0

Where V0 is the initial velocity of the car, we know that this is 88 ft/s

Then the velocity equation is:

V(t) = (-10 ft/s^2)*t + 88ft/s

To get the position equation we need to integrate again, this time we get:

P(t) = (1/2)*(-10 ft/s^2)*t^2 + (88ft/s)*t + P0

Where P0 is the initial position of the car, we do not know this, but it does not matter for now.

We want to find the total distance that the car traveled in a 3 seconds interval.

This will be equal to the difference in the position at t = 3s and the position at t = 0s

distance = P(3s) - P(0s)

= ( (1/2)*(-10 ft/s^2)*(3s)^2+ (88ft/s)*3s + P0) - ( (1/2)*(-10 ft/s^2)*(0s)^2 + (88ft/s)*0s + P0)

Elastic potential energy is initially at rest, making it move.

Elastic potential energy is what causes a ball to bounce or rebound because it is transformed into kinetic energy and used to raise the ball back up. However, because some of the ball's energy was transferred to the ground or changed into sound (in the noise it makes upon impact) and heat energy, the ball won't go as high as it did at first (friction with the table). Additionally, even though we cannot see it, the ball alters once it strikes the ground or a table, energy is needed to take shape for a brief period of time.

Because of this, each bounce has a slightly lower height than the one before it. The ball has some kinetic energy when it hits the floor, but some of it is changed, so it loses some of it each time it bounces. After a few bounces, the ball has so little kinetic energy remaining that it stops bouncing.

Thus the correct answer is option A.

Answer:

The river current influences the motion of the boat and carries it downstream. The motorboat may be moving with a velocity of 4 m/s directly across the river, yet the resultant velocity of the boat will be greater than 4 m/s and at an angle in the downstream direction.

Explanation:

From the total plate count assay, the  colony forming units/ml (CFU/ml) of the original sample is 2.1 * 10⁸ CFU/mL.

The the Colony Forming Units/ml (CFU/ml) of a given sample of of cultured bacteria is a measure of the number of colonies formed per given mL f the final diluted sample of the cultured bacteria.

The formula for calculating the Colony Forming Units/ml (CFU/ml) of a given cultured bacteria sample is given as follows:

Where:

FDF is the final dilution factor

The final dilution factor is the product of all the dilution factors from the original sample to the countable plate.

From the dat provided:

FDF = 1 * 10⁻⁶

number of colony forming units on the countable plate = 210

The colony forming units/ml (CFU/ml) of the original sample = 210 * 1/1 * 10⁻⁶

The colony forming units/ml (CFU/ml) of the original sample = 2.1 * 10⁸ CFU/mL
