Which is the most accurate statement about the heating curve and energy?

a) moving from a to c the temperature and the kinetic energy increases.

b) moving from c to a the temperature decreases but the kinetic energy increases.

c) although the temperature increases, there is no information about energy change.

d) as time elapses, the substances turns into plasma and has the highest kinetic energy.

What happens to light waves from a star as the star moves away from earth?

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
