Answer: the volleyball
Explanation:
The volleyball, in contrast, is full of air, which contains fewer, more widely spaced particles of matter. In other words, the matter inside the bowling ball is denser than the matter inside the volleyball. A bowling ball is denser than a volleyball.
Answer:
1) joule
2)
3)
Explanation:
1) Luminosity is the <u>amount of light emitted</u> (measured in Joule) by an object in a unit of<u> time</u> (measured in seconds). Hence in SI units luminosity is expressed as joules per second (), which is equal to Watts ().
This amount of light emitted is also called radiated electromagnetic power, and when this is measured in relation with time, the result is also called radiant power emitted by a light-emitting object.
Therefore, if we want to calculate luminosity the Joule as a unit will be used.
2) Work is expressed as force multiplied by the distane :
Where force has units of and distance units of .
If we input the units we will have:
This is 1Joule () in the SI system, which is also equal to
3) The formula to calculate the percent error is:
Where:
is the experimental value
is the accepted value
This is the percent error
Venus is the second planet from the sun. It is usually the brightest object in our sky, other than our sun and moon. At sunrise and sunset, it looks like a big, bright star. It is bright because Venus has a cloud cover that reflects the sunlight. These clouds are made up of gases.
Protons are the subatomic particle that lies in the nucleus of an atom
When a small cart collide with a large mass then during collision they must be in contact with each other for some interval of time
During this contact interval we can say they will exert normal force on each other
This normal force is always equal and opposite on two balls which means this force will follow Newton's III law
It will be same in magnitude but opposite in the direction
So here correct answer would be
<u><em>They both experience the same magnitude of the collision force.</em></u>
