A worker pushes a crate horizontally across a warehouse floor with a force of 245 N at an angle of 55 degrees below the horizontal. How much of the worker’s force is not used to move the crate?

200.66 N

Explanation:

We are given that

Force,F=245 N

We have to find  the force of worker is not used to move the crate.

Force along x- axis=

It acts in the direction of displacement.Therefore, it is used to move the crate.

Force along y- axis=

It is not used to move the crate.

Hence,the worker's force  which is not used to move the crate=200.66 N

i think it's 35 meters

if i am correct, your answer choices are:

a. the temperature remains constant

b. the temperature increases at a constant rate

c. heat flows at a constant rate into the system

d. heat flows at a constant rate out of the system

e. no heat flows into or out of the system

if so, then the answer is e. no heat flows into or out of the system.
