The applied force is parallel to the ground, so the net vertical force on the sled is 0. By Newton's second law, this means the normal force and weight of the sled cancel out:

<em>n</em> - <em>w</em> = 0

<em>n</em> = <em>w</em>

<em>n</em> = <em>m g</em>

<em>n</em> = (15.7 kg) (9.80 m/s²)

<em>n</em> = 153.86 N

A pendulum consists of a massless stiff rod of length L hanging from a nearly frictionless axle, with a mass m at the end of the
Dennis_Churaev [7]

Answer:

mgL(1 - cosθ)

Explanation:

At angle θ, the vertical distance from the mass m to the pivotal axle is Lcosθ. While at U=0, this distance is L. Due to the mass is hanging straight down. Therefore the vertical distance from this lowest point to point at angle θ is

L - Lcosθ

The change in potential energy would be this height difference times mg

U_{\theta} = mg\Delta h = mg(L - Lcos\theta) = mgL(1 - cos\theta)

where g is the gravitational constant

Describe the shape of a convex lens and explain what it does to light.
alexira [117]
Convex lenses are thicker at the centers than the edges, they are known as the converging lenses. Rays of light that pass through the lens are brought closer together (they converge). When rays of light that are parallel pass through a convex lens they are refracted, the refracted rays converge at one point called the principal focus.
