The frequency of oscillation on the frictionless floor is 28 Hz.
<h3>
Frequency of the simple harmonic motion</h3>
The frequency of the oscillation is calculated as follows;
f = (1/2π)(√k/m)
where;
- k is the spring constant
- m is mass of the block
f = (1/2π)(√7580/0.245)
f = 28 Hz
Thus, the frequency of oscillation on the frictionless floor is 28 Hz.

The law of reflection states that "when a ray of light is reflected off a surface, the angle of incidence equals to the angle of reflection"
The angle of incidence is 62° means the angle of reflection is also 62°
Answer:
longer wavelength and lower frequency
shorter wavelength and greater frequency
Explanation:
f = v/l
l = wavelength
v = speed of wave
f = frequency
Answer:
has free electrons
Explanation:
A conductor has free electrons while an insulator does not. Free electrons are electrons which are not bounded tightly to their parent atoms, and are free to move given the right conditions (ie. a strong EM field).
