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
If you are talking about gravitational potential energy, then the ONLY way to either increase OR decrease it is to raise or lower your height. The higher you are off the ground the greater your PE, the closer you are to the ground, the lower your PE
Answer:. 1008
7×9= 63 square meters total area.
Each square meter is 100 cm wide and 100 cm long. 100÷25 = 4, so it will take 4 tiles wide and 4 tiles long for each square meter. 4×4= 16
Multiply 16 × 63 = 1008 tiles needed.
