B and C! I like to think of projectile motion as a motion that doesn’t go in a straight line, it has two directions.
Answer:
momentum of iron ball is greater than wooden ball
Explanation:
when metal ball (iron ball) and wooden drop are drop from same elevation and reaching the ground after same time. at this position the iron ball has greater momentum than wooden ball
we know that momentum is defined as
P=Mv
and we know also that mass of iron ball is greater than mass of wooden ball and they reached on ground at same time and same distance it mean also velocity will be same for both ball. therefore from above relation we have
Miron*V > Mwood*V i.e.
momentum of iron ball is greater than wooden ball
5 N to the right
There’s a force of 6 N pulling to the right (the positive direction) and 1 N pulling left (the negative direction).
Net force= 6 N - 1 N = 5 N to the right
They would feel warmer cause black attracts heat and also could attract bees
Answer:
B. Chemical changes involve the formation of a new substance.
Explanation:
They can both release energy, both can be measured, and chemical changes can be caused by oxygen, so I believe it would be B.
