Answer:
b) Springs oscillate with the same frequency,
Explanation:
expression for frequency of vibration of mass hanging from a spring is given as follows
f =
k is force constant of spring and m is mass vibrating .
In the present case, if mass stretches the spring by x and remains balanced
mg = k x
g and x are same for both cases
will also be same for both cases .
Hence frequency of vibration will also be same for both the balls .
Because gravity accelerates all objects the same regardless of their mass
Answer:
Here are the em radiation in order of increasing frequency from left to right. Also, the wavelength decreases as we move from left to right.
Radio, micro, infrared, visible, ultraviolet, x-ray and gamma ray.
According to quantum physics, you use E = hf ( where E = energy of a photon of a type of em wave, h is Planck constant and f is frequency of that photon ) to find the energy.
From here you can see that as we move from left to right, energy increases because frequency increases.

Answer:
The two people would fall down according to the laws of physics by Sir Issac Newton
Explanation:
Also write this (according to my unit I teach to my kids since I am a teacher but don't tell anyone): Just like if an apple were to fall, the tree would go upwards and the apple would fall. :)
