Explanation:
The question says that "Does a 60 kg person running at 4 m/s have more kinetic energy than a 10 gram projectile at 300 m/s ?
"
Speed of a person is 4 m/s
Mass of a person is 60 kg
Kinetic energy of a person is : 
So,

Mass of a projectile is 10 grams or 0.01 kg
Speed of a projectile is 300 m/s
Kinetic energy of a projectile is :


So, it is clear that the kinetic energy of a person is more than that of the kinetic energy of a projectile.
Pretty sure it is clockwise if I am not mistaken
Answer:
14.167 m/s
Explanation:
Average speed = Total distance/Total time taken.
Average speed = 170/12 - 0 = 170/12 = 14.167 m/s
Answer:
30 percent is found in ground water.
Answer:
hmm
Explanation:
By increasing the number of turns in the coil, strength of magnetic field, speed of rotation of the coil in the magnetic field and by decreasing the distance between the coil and the magnet the magnitude of the induced e.m.f. can be increased in generator/dynamo.
