plz mark brainliest again lol :)
Explanation:
When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
<span>the one that should be taken as consideration when describing the quality of a sound is: D.The number of the overtones in the sound
Too many overtones indicated that there is too many unrelated sound that make a lot of the sound's part became redundant and unecessary</span>
Answer:
Explanation:
We need the power equation for this which is
P = Work/time
We have everything we need to solve this (the mass of the object is extra information):
P = 6860/4
P = 1715W
Gravitational field strength (GFS) on earth =10 N/kg
Weight = GFS x mass
W = 10 x 7
W = 70N
70N = 15.74 pounds
