Answer:
To change.
Explanation:
The Law of Conservation of energy states that energy cannot be destroyed but can only be transformed or converted from one form to another. For example, light energy to heat energy.
When a material absorbs energy from light the energy causes the material to change.
Answer:
Fc = 7.14N
Explanation:
First of all, let's convert everything to the same unit system:
m = 0.0031kg R = 13.1cm * 1m / 100cm = 0.131m
ω = 50000 rev/min * 1rev /( 2π rad ) * 1min / 60s = 132.63 rad/s
Now we can calculate centripetal force as:
Replacing the values we get the answer:
Fc = 7.14N
It has changed because earlier in the days people couldn't even figure out if the world was flat or round but now we can add decimals and multiply fractions.
Answer:
The answer is radio waves
This is true. There is a downward force on the table that stabilizes the rock to stay there.
