D. A heat engine that uses heat to do work

Explanation:

A coal fired power plant is a heat engine that uses heat to do work.

A heat engine is a device that is used to convert heat energy into mechanical energy .

A heat pump uses mechanical energy to produce more heat from a lower heat sink.

A coal power plant produces heat by firing the coal.
Heat from the coal combustion heats water to steam.
The steam is used to drive heavy turbines
The turbine has mechanical energy and it then produce electricity.

Thank you for posting your Physics question here. I hope the answer helps. Upon calculating the ramp with the horizontal the answer is 20.49 Deg. Below is the solution:

Y = 7 m.
r = 20 m. 

sinA = Y/r = 7/20 = 0.35. 
A = 20.49 Deg.

A box is initially sliding across a frictionless floor toward a spring which is attached to a wall. the box hits the end of the

Serjik [45]

The elastic potential energy of a spring is given by
$U= \frac{1}{2}kx^2$
where k is the spring's constant and x is the displacement with respect to the relaxed position of the spring.

The work done by the spring is the negative of the potential energy difference between the final and initial condition of the spring:
$W=-\Delta U = \frac{1}{2}kx_i^2 - \frac{1}{2}kx_f^2$

In our problem, initially the spring is uncompressed, so $x_i=0$ . Therefore, the work done by the spring when it is compressed until $x_f$ is
$W=- \frac{1}{2}kx_f^2$
And this value is actually negative, because the box is responsible for the spring's compression, so the work is done by the box.
