Answer:
The answer is D.
Explanation:
This is because mass always remains constant and weight is dependent on a gravitational pull.
A) The ball on the small ball is far smaller than the force on the basketball.
B) The total momentum before and after the collision remains constant.
C) We know momentum is conserved so we do:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.1 x 5 + 0.6 x 0 = 0.1 x -4 + 0.6 x v₂
v₂ = 1.5 m/s
Explanation:
Speed is distance over time.
500 km / 2 hr = 250 km/hr
Velocity is speed and direction.
250 km/hr north
Answer: It's A
conduct smaller studies for more than a one-year period
Answer:
b) one-third as great.
Explanation:
As we know that same heat is supplied in this experiment
so we will have

now we know that both are initially at same temperature
then their final temperatures are


now we have

so we have

so heat capacity of mystery metal is 1/3 times that of water
