Answer:
the two balls will hit the ground at the same time.
Explanation:
The time of dropping, in the following equation, is related to both the distance travel s and the gravitational acceleration g, which are the same for both ball (if we neglect air resistance), no matter what their mass are.


So the time it takes to drop 2 balls are the same. They will hit the ground at the same time.
They are called mechanical waves
B is the correct answer
y=Asin(wt-kx)
A=amplitude
f=frequency
x=wavelength
since refraction is not on the wave formula,then option B is the correct answer
Answer:
Newtons
Explanation:
Magnitude of charge on the electron = q =
Coulombs
The negative sign in the question statement indicates that the charge is negative.
Magnitude of Electric Field experienced by the electron = E =
Newtons/Coulomb
Magnitude of Force on the electron = F = ?
The relation between the charge, electric field and the force on the charge because of electric field is given by:

From here we can write:
F = qE
Using the values, we get:

Thus, the magnitude of the electric force experience by the electron would be
Newtons
Answer:
The second universal law, the law of vibration, posits that everything (every atom, object, and living thing) is in constant motion, vibrating at a specific frequency.
