In a shipping yard, a crane operator attaches a cable to a 1,400 kg shipping container and then uses the crane to lift the container vertically at a constant velocity for a distance of 40 m. determine the amount of work done (in j) by each of the following.

Explanation:

Given

mass of crane

distance moved

Since it is moving with a constant velocity therefore net force on it is zero

Tension force=weight

T=mg

Work done by Tension T is

Work done by Gravity will be equal in magnitude but opposite in sign and can be obtained by work energy theorem which states that change in kinetic energy of object is equal to work done by all the forces

radiation

explanation:

heat is transmitted by radiation

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
