Answer:
1.327363 m/s
0.00090243 m
Explanation:
u = Initial velocity
v = Final velocity
m = Mass of flea
Energy
The velocity of the flea when leaving the ground is 1.327363 m/s
The flea will travel 0.00090243 m upward
Explanation:
Following are two interactions that are generally involved when we use a TV remote control to change the channel :
1. Figure touches remote buttons, and its a short range interaction.
2. Now remote sends signal to Television, this is a long range interaction.
Answer:
energy which a body possesses by virtue of being in motion.
Explanation:
Answer:
C
Explanation:
- Let acceleration due to gravity @ massive planet be a = 30 m/s^2
- Let acceleration due to gravity @ earth be g = 30 m/s^2
Solution:
- The average time taken for the ball to cover a distance h from chin to ground with acceleration a on massive planet is:
t = v / a
t = v / 30
- The average time taken for the ball to cover a distance h from chin to ground with acceleration g on earth is:
t = v / g
t = v / 9.81
- Hence, we can see the average time taken by the ball on massive planet is less than that on earth to reach back to its initial position. Hence, option C
