Answer:
Explanation:
The Term "For every action, there is an equal and opposite reaction" is derived from Newton's third law of motion.
This can be explained by an example of a block placed on the flat surface.
The weight of the block applies an action force on the surface while Surface applies a reaction force on the block. Action and reaction force applies to different bodies other would have canceled each other. Action and reaction forces are always acting in pairs. The magnitude of reaction force depends upon the action forces as both of them are equal in magnitude but opposite in direction.
Answer:
Explanation:
By ideal gas equation law we know that
PV = nRT
now we know that when balloon rises to certain level then the number of moles will remains same
so we can say
now plug in all data to find the final volume of the balloon
If the box is moving at constant velocity, net force must be zero, so:
F + fr = 0
fr = -F
<u>fr = -40 N</u>
You'd get an extra 40/60 of the energy, or 2/3. Multiply 5/3 by the required energy to get the actual consumption.
