Answer:
His weight would be 100 N
Explanation:
Answer:
The bowling ball did not change size or shape- the only thing that changed was the amount of gravity that pulls on it. But the mass of the bowling ball would never change. A bowling ball with a mass of 12 pounds on earth will have the mass of 12 pounds on the moon! Mass is the amount of atoms that a space fills.

I hope this helps! :D
Answer:
159.38 Watts
Explanation:
Initially;
- Mass on the spring is 8.5 kg
- Therefore, compression force is 85 N
- Compression distance is 15 cm or 0.15 m
But;
F = kx
where F is the force of compression, k is the spring constant and x is the compression distance.
Thus;
k = F/x
= 85 N ÷0.15
= 566.67 N/m
We are required to determine the power needed to stretch the same spring for 1.5 m in 4 secs.
Power = Work done ÷ time
Work done is given by 0.5kx²
Therefore;
Power = 0.5kx²÷ t
= (0.5×566.67 N/m × 1.5² ) ÷ 4 seconds
= 159.38 Watts
Thus, the power needed is 159.38 watts
Answer:
Explanation:
(a)
Since the earth is assumed to be a sphere.
Volume of atmosphere = volume of (earth +atm osphere) — volume of earth
Hence the volume of atmosphere is 
(b)
Write the ideal gas equation as foll ows:
Hence the required molecules is 
(c)
Write the ideal gas equation as follows:
Hence the required molecules in Caesar breath is 
(d)
Volume fraction in Caesar last breath is as follows:
(e)
Since the volume capacity of the human body is 500 mL.
Answer:
At the instant shown in the diagram, the car's centripetal acceleration is directed is discussed below in detail.
Explanation:
The direction of the centripetal acceleration is in a circular movement is forever towards the middle of the roundabout pathway. In the picture displayed, the East direction is approaching the center. So, the course of the car's centripetal acceleration is (H) toward the east.
