Answer:
"The bowling ball on Earth will have a greater potential energy relative to the surface because the Earth has a much greater mass, and therefore a much stronger gravitational acceleration."
Explanation:
Potential energy acts as a result of the object placed over the Earth's surface, The object has the ability to fall because of the gravitational force. Gravitational potential energy is based on the weight of the object and also the height above the ground surface. But the elastic potential energy acts due to the shape of the object. Potential energy is related with the restoring of the forces which is the spring or the force of the gravity.
ANSWER:
a. 50.53 km/h
b. 32.53 km/h (in the direction of 25˚ S of E)
c. 4.27 km/h
d. 0 km/h
STEP-BY-STEP EXPLANATION:
a.
We have that the speed is given by the following formula:
We know that the equivalence between minutes and hours is that 60 minutes equals 1 hour, therefore:
b.
The velocity is given by the following formula
c.
The total distance traveled would then be two 16 kilometers, that is 32 km and the time would be 7.5 hours. we replace
d.
Since it starts in the same place that it ends, the displacement is equal to 0, therefore, the velocity is equal to 0 km/h
Answer:
1.0s
Explanation:
distance = 1/2 × acceleration × time2 + intial speed × time
Solid to liquid: molecules spread out to have their own spaces and move energetic and lively.
