Answer:
Frequency = 24 × 10⁸ Hz
Explanation:
Given the following data;
Speed = 3 × 10⁸ m/s
Wavelength = 0.125 meters
To find the frequency of the electromagnetic wave;
Mathematically, the speed of a wave is given by the formula;
Speed = Wavelength × frequency
Substituting into the formula, we have;
3 × 10⁸ = 0.125 × frequency
Frequency = (3 × 10⁸)/0.125
Frequency = 24 × 10⁸ Hz
This can be explain through Newton’s first law of motion where an
object at rest remain in rest unless acted upon by an unbalanced force. Hence,
the dust particles having inertia and trapped within the pores of the carpet
has the tendency to remain at the state of rest, it does not move and resist
motion but when the carpet is beaten with a stick, dust comes out because the
force from a stick acted upon it.
Answer:
moving charges b)
I think this is the answer
