If you push Force is just a fancy word for pushing or pulling.
Answer:
Equal to c ( b )
Explanation:
The speed of the light will be Equal to C because the speed of light regardless of the speed of the Train, length of the car and the medium in which the light travels the speed of light remains the same ,
The speed of light ( c ) is equal to : 299792458 m / s and no object can travel faster than light therefore the speed of light from the flashlight will remain the same over the whole time it travels through the medium or distance that it is found.
The magnet (south pole of the magnet) has magnetized the right side of the block.
<h3>
Direction of electric field in the magnetic material</h3>
The direction of electric field of the atom of the magnetic material is unpolarized.
From the diagram in the image, the right hand side of the magnetic material is being attracted to south pole of the magnet.
Thus, we can conclude that, the magnet has magnetized the right side of the block.

Answer:
B. -900 kg-m/s2
Explanation:
First of all, we need to calculate the acceleration of the hockey player, which is given by:
where
v = 12 m/s is the final speed
u = 18 m/s is the initial speed
t = 0.6 s is the time
Substituting into the formula, we find
And now we can calculate the force exerted by using Newton's second law:
where m=90 kg is the mass of the hockey player. Substituting into the formula, we find
Did we invent math or did we discover it?
