A mule uses a rope to pull a box that weighs 145 N across a level surface with constant velocity. The rope makes an angle of 25.0° above the horizontal, and the tension in the rope is 85 N. What is the normal force of the floor on the box?

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

a) the event horizon, singularity, and the chute located between the two.

just copy what u wrote and paste and search in google
