Answer:
Dependent variable.
Explanation:
Based on the description, the experiment is designed to confirm or reject a hypothesis about a heat absorption patterns by hollow objects with different transparency. Temperature appears to be the main target variable of interest - this is the <em>dependent</em> variable. Material that each box is made of (specifically, its transparency) is in this case the independent variable, which is determined by the experimenter.
The correct option is D.
The critical angle is defined as the angle of incidence, which provides an angle of refraction of 90 degree. At any angle of incidence greater than the critical angle, all the light will totally reflected, resulting in total internal reflection.Thus, the critical angle is equal to the refractive index.
Answer:
C) The force experienced by the ball equals the force experienced by the club.
Explanation:
When the golfer strikes the ball with his club, the club exerts a force on the ball. Due to Newton's Third Law Of Motion [Every Action has an equal and opposite reaction], the ball also exerts an equal force on the club. However,
As the mass of the club is usually greater than the mass of the ball, it accelerates slower; While the ball way faster, following the equation : F=ma
