Answer:
4306.8625 J or 344549/80J (fraction form)
Explanation:
kinetic energy= 
mv²
= 
×72.5×10.9²
= 4306.8625 J or 344549/80 J
Answer:
1960.32306 kg/s
Explanation:
m = Mass of water = 1 kg
g = Acceleration due to gravity = 9.81 m/s²
h = Height from which the water will fall
Potential Energy
One megawatts of power is required
So, flow rate
1960.32306 kg/s is required to produce a megawatt of power
Period: Time it takes to complete a cycle, it takes 0.5s to complete a cycle
Frequency: Number of cycles in a second. Since 0.5s = 1 cycle, 1s=2 cycles
Period is 0.5s, frequency is 2
Answer: That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.
Explanation: Because Earth-orbiting objects follow elliptical paths around Earth and not a straight line, forces cannot, by definition, be balanced. Force is directional. It is a push or a pull in a particular direction.
