C. A mechanical wave generally travels faster in gases than liquids.
Momentum (P) = Mass (kg) * Velocity (m/s)
P = M * V
P = 50 * 5
P = 250
So momentum is 250 kgm/s
That you have thrown a ball with kinetic energy upwards at an increasing velocity rate
Answer:
18min
Explanation:
v=d/t
t=d/v= 27/90 =0.3hrs =18min
Answer:
The gravity is pulling the diver downwards but the rotation of the body means gravity cant pull him down as quickly
