Answer:
True
Explanation:
The normal line is defined as the line which is perpendicular to the reflecting surface at the point where the incident ray meet with the reflecting surface.
The angle of incident is defined as the angle which is subtended by the incident ray with respect to the normal ray by consider the normal ray as the base line and angle is measured from the point where incident ray is incident on the reflecting surface of the mirror.
Similarly reflecting ray can be defined as the ray which is reflected after the incident of a ray and the angle subtended by the reflecting ray is measure with respect to normal ray by considering normal ray as a base line.
Therefore, the normal ray is the perpendicular line to the reflecting surface at the point of incidence.
When the mass is 5.0 cm from its equilibrium point, the percentage of its energy that is kinetic is 75%.
<h3>Total energy of the mass</h3>
The total energy possessed by the mass under the simple harmonic motion is calculated as follows;
U = ¹/₂kA²
where;
- k is the spring constant
- A is the amplitude of the oscillation
P.E = ¹/₂k(Δx)²
<h3>Kinetic energy of mass</h3>K.E = U - P.E
K.E = ¹/₂kA² - ¹/₂k(Δx)²
<h3>Percentage of its energy that is kinetic</h3>Thus, when the mass is 5.0 cm from its equilibrium point, the percentage of its energy that is kinetic is 75%.
