Explanation:
Light is clearly affected by gravity, just think about a black hole, but light supposedly has no mass and gravity only affects objects with mass. On the other hand, if light does have mass then doesn't mass become infinitely larger the closer to the speed of light an object travels.
Answer:
Momentum (p) is equal to the product of an object's mass (m) and its change in velocity (v).
Change in velocity (v) results in change in momentum (p), which is equal to impulse. Impulse (J) is also equal to an applied force (F) over a period of time (t).
Combining p=mv and J=F t together:
m (v final - v initial) = F t
(2,500 kg) (70 m/s - 30 m/s) = F (10 s)
Explanation:
Solving for F we get:
10,000 N of force
The correct answer to this problem would be that like poles repel and unlike poles attract.
N and N poles repel
S and S poles repel
N and S poles attract
S and N poles attract
Answer: D) like poles repel each other. unlike poles attract each other
I hope this helps!
