Explanation:

C. has the box on the colors, which is the rainbow because it is the visible light we are able to see.

Answer:C

Explanation:

Answer:

A

Explanation:

You can rule out c and d since they make no sense but i would say a makes more since than b since your sitting on the chair your putting force on it

Answer: Core muscles protect the spine and keeps it stabilized. Also they can help control movements such as walking and standing. The core helps transfer energy and help us move in different directions. It's important to have a strong set of core muscles.

Explanation:

Answer:

The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

Answer:

It turns out that an object's kinetic energy increases as the square of its speed

Explanation:

A car moving 40 mph has four times as much kinetic energy as one moving 20 mph, while at 60 mph a car carries nine times as much kinetic energy as at 20 mph.

basiclly the faster the more impact it has when it suddenly stops or hit somthing

Answer:

extrusive igneous rock

Answer:

Time, t = 0.015 seconds.

Explanation:

Given the following data;

Mass, m = 0.2kg

Force, F = 200N

Initial velocity, u = 40m/s

Final velocity, v = 25m/s

To find the time;

Ft = m(v - u)

Time, t = m(v - u)/f

Substituting into the equation, we have;

Time, t = 0.2(25 - 40)/200

Time, t = 0.2(-15)/200

Time, t = 3/200

Time, t = 0.015 seconds.

Note: We ignored the negative sign because time can't be negative.

Answer:

It conserves both energy and momentum in the collision at the same time. By design, when the balls collide the strings that hold them up are vertical (assuming balls are only swung from one side).

Answer:

True.

Explanation:

The given statement is true that the law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.

According to this law, the forces between two masses can be calculated by the product of their masses and divided by the square of the distance between them. Mathematically, it can be written as :

[tex]F=\dfrac{Gm_1m_2}{r^2}[/tex]

G is universal gravitational constant

Hence, the given statement is true.

Answer:

68.6N

Explanation:

Given parameters:

Mass of object  = 7kg

Unknown:

Weight  = ?

Solution:

The weight is the downward force of gravity on a body;

              Weight  = mass x acceleration due to gravity

             Weight  = 7 x 9.8 = 68.6N

Answer:

Input Force

Explanation:

Answer:

resistance distance.

Explanation:

Explanation:

Given

Mass(M) = 80,000 kg

Acceleration (a) = 35 m/s²

Force (F) = ?

We know we have the formula

F = m * a

= 80000 * 35

= 2800000

= 2.8 * 10 ^ 6 N

The force is 2.8 * 10 ^ 6 N.

Hope it will help :)❤

If a rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2.  then the force that provides this acceleration would be 2800000 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The mathematical expression for Newton's second law is as follows,

F = m*a

As given in the problem we have to find the force that provides the acceleration of 35 meters / second², if the  rocket has a mass of 80,000 kg,

The force acting on the rocket =  80,000 × 35

                                                   = 2800000 Newtons

Thus, the force acting on the rocket would be 2800000 Newtons.

Answer:

light potential energy is converted into electrical potential energy.

Explanation:

A solar heat absorbs the light that creates pairs of electron - holes, these free charges when moving create a current, the light energy stored in the radiation is converted into electrical energy within the n-p junctions.

In summary, light potential energy is converted into electrical potential energy.

A horizontal net force F is exerted on a 2.0 kg object at rest. The object starts at x = 0 m and travels 4.0 m along a horizontal frictionless surface. The net force F as a function of the object's position x is shown below.

What is the velocity of the object?

Answer: 12 m/s

Answer:

Ep=mxgxh.

a) m=ep/gxh

b) g=ep/m/h

c)h=ep/mxg

Answer:

Ep=mgh

Ep/gh=mgh/gh

Ep/gh=m

Answer: 36 m/s

Explanation:

Wave speed = Wavelength * Frequency

Explanation:

Remember Newton's Second Law.

[tex]F=ma[/tex]

If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.

If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. [tex]100 = 10*a_1 \rightarrow a_1 = 100/10 = 10[/tex]

[tex]100 = 20 *a_2 \rightarrow a_2 = 100/20 = 5[/tex]

So, given the same force, an object with GREATER mass will have less acceleration.

Answer:

3.88 m/s North

Explanation:

We are given that

[tex]m_1=136kg[/tex]

[tex]m_2=100 kg[/tex]

[tex]v_1=6 m/s[/tex]

[tex]v_2=1m/s[/tex]

We have to find  the speed and direction of the two players

immediately after the tackle.

Using linear conservation of momentum

[tex]m_1v_1+m_2v_2=(m_1+m_2)v[/tex]

Substitute the values

[tex]136\times 6+100\times 1=(136+100)v[/tex]

[tex]916=236v[/tex]

[tex]v=\frac{916}{236}[/tex]

[tex]v=3.88m/s[/tex]

Direction of  the two players  immediately after the tackle is North.
