Answer:
magnification is 4
Explanation:

m= 4
Answer:
D
Explanation:
It is important that we have two variables, Independent
and Dependant Variable.
Electromagnetic (EM) frequency = f Hz
Wavelength = λ m
f = c / λ, c = f λ:
Answer:
under
Explanation:
We know that F = ma,
or, a = F/m
or, a = 120/30 (because, Force = 120 N and mass = 30 kg)
or a = 4m/s^2
Hence, the acceleration of the object is 4 meter per second squared.
