Answer:
268N
Explanation:
The upward force acting on the block are the reaction and the hooked table..
The total normal force acting = normal reaction + 24N
Note that the normal reaction is always equal the weight of the table
Hence the normal force acting in the block is 244.0+24 = 268.0N
Answer:
The red car would experience the greatest acceleration.
Explanation:
Newton says that Force equals mass times acceleration or F = ma
We get a = F/m
If we want the greatest acceleration or a, mass or m must be the lowest.
<span>energy is directly proportional fo frequency
as in blue photons are more energetic than red photons
so
E = h * f
look up h (Planck's constant)
plug and play!</span><span>

Answer:
A sound wave that has a higher frequency is a wave that makes 12 cycles per second.
Explanation:
The frequency of a wave is the same as the frequency of the vibrations that caused the wave. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
I think it would be atomic energy, which would most likely be in very short waves to affect the protons.
