Answer:
17640
Explanation:
Power = workdone/time
Power = (force x displacement)/time
Power = (mg x 60)/60
Power = (1800 x 9.8 x 60)/60
=> power = 17640 watt
Answer:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. ... Applied to a more complex system below, such as a hydraulic car lift, Pascal's law allows forces to be multiplied.
Explanation:
Answer:

Explanation:
From the question we are told that:
Mass 
Height 
Speed 
Angle 
Generally the equation for K.E is mathematically given by
Since
The potential energy and kinetic energy is equal to the kinetic energy as it hits the ground.
Therefore



Gain in decibels is given by;
Gain db = 10*log (Po/Pi), where Po = Power output, Pin = Power input
Substituting;
Gain in db = 10 * log (50/5) = 10 db
