A 100kg sumo wrestler named Bob is doing his daily run. He runs at a velocity of 8m/s. After the run Bob stops for a rest, and s
Elza [17]

Answer:

0 kgm/s

Explanation:

The momentum of Bob while resting at the river is 0 kgm/s.

This is because the momentum of any object at rest is 0.

 Momentum is the quantity of motion a body contains. It is mathematically expressed as;

  Momentum  = m x v

m is the mass

v is the velocity

 So at rest, the velocity of a body is 0m/s and therefore, the momentum is O

A 3.00 L flexible container holds a sample of hydrogen gas at 153 kPa.
Lisa [10]

The volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L (option B).

<h3>How to calculate volume?</h3>

The volume of a substance can be calculated using the following formula:

P1V1 = P2V2

Where;

  • P1 = initial pressure
  • P2 = final pressure
  • V1 = initial volume
  • V2 = final volume

153 × 3 = 304 × V2

459 = 304V2

V2 = 459/304

V2 = 1.51L

Therefore, the volume of the flexible container that holds a sample of hydrogen gas at 153 kPa is 1.51L.
