Answer:
Every action has an equal and opposite reaction. If the student doesn't push, nothing moves, is one student pushes, both move which is an example of newtons third law.
Explanation:
A) Vector A
The x-component of a vector can be found by using the formula

where
v is the magnitude of the vector
is the angle between the x-axis and the direction of the vector
- Vector A has a magnitude of 50 units along the positive x-direction, so
. So its x-component is

- Vector B has a magnitude of 120 units and the direction is
(negative since it is below the x-axis), so the x-component is

So, vector A has the greater x component.
B) Vector B
Instead, the y-component of a vector can be found by using the formula

Here we have
- Vector B has a magnitude of 50 units along the positive x-direction, so
. So its y-component is

- Vector B has a magnitude of 120 units and the direction is
, so the y-component is

where the negative sign means the direction is along negative y:
So, vector B has the greater y component.

The period of the simple pendulum is:

Where:
- Cord length, in m.
- Gravity constant, in
.
Given that the same pendulum is test on each planet, the following relation is formed:

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:



Answer:
The following that could be used to make the simplest circuit are a battery, wire, switch, and a light bulb. The answer is letter D. The battery provides the energy for the bulb to work. The wire provides a pathway for the electrons to move. The switch provides the open and close of the circuit.

Hopefully this helped, if not HMU and I will get u a better answer
-Have a great day! :)
The center-seeking change in velocity of an object moving in a circle is the centripetal acceleration.
So, by Newton's laws, we know that an object moving with a given velocity will remain in constant motion with a constant velocity until we apply an acceleration.
So we define acceleration as the rate of change of the velocity, also remember that velocity is a vector (has magnitude and direction), so, if there is a change the direction of the velocity, we have an acceleration that causes that.
In circular motion, the velocity vector is always perpendicular to the radius of the circle, and it can only be possible if the velocity direction is changing constantly. This will happen because of something called centripetal acceleration.
This acceleration points radially inwards (to the center of the circle) so is also perpendicular to the velocity of the moving object, and this is what causes the constant change in the direction of the velocity of the moving object.
Just to give an example, if you have a string with a mass on one end, and with your hand, you rotate the mass (from the string), the tension of the string would be the centripetal acceleration.
