Askier is accelerating down a 30.0 degree hill at 3.80 m/s2. how long (in seconds) will it take her to reach the bottom of the hill, assuming she starts from rest and accelerates uniformly, if the elevation change is 130 m?

t = 11.69s

Explanation:

The distance traveled by the skier is given by:

  where H=130m

D = 260m

Now, the movement down the hill is described by:

 Solving for t:

yes.

Explanation: The light that will be incidented on that metal is visible light.

It depends on 3 factors:

1. The temperature

2. The specific heat capacity of the metal

3. The thermal conductivity of the metal.

The metal getting warmer also depend on the reflection and the absorption of light energy in which it will surely absorb some energy and not reflect all.

When visible light is absorbed by an object, the object converts the short wavelength light into long wavelength heat. This causes the object to get warmer.
