Answer:
D- component of the gravitational force parallel to the plane increased and normal force exerted by the board decreased
Explanation:
component of the gravitational force parallel to the plane = mg sinθ ; where θ is inclination of the plane . As it increases , sinθ increases and hence component of the gravitational force parallel to the plane increases .
normal force exerted by the board = mg cosθ . As θ increases , cosθ decreases and hence normal force exerted by the board decreases and hence friction force decreases because
Friction force = coefficient of friction x normal force exerted by the board .
coefficient of friction remains constant.
It would be 5 mph. Hope it helps! :)
According to research, none of these men were executed for believing that Earth revolves around the sun. Nicolaus Copernicus was the first to believe in the heliocentric view of the current solar system, but he was not killed for that view, but he died of natural means. Galileo Galilei was punished because of the heliocentric view but was only put under house arrest, and not killed. Giordano Bruno was indeed burned at stake, but it was not for his view on heliocentrism.
