When a force applied to a breaker bar the torque can be calculated by multiplying the<u> length of the lever</u> by the tangential component of force on the lever.
<h3>What is torque?</h3>
Torque is the <u>rotating equivalent</u> of force in physics and mechanics. Depending on the subject of study, it is also known as the moment, moment of force, rotating force, or turning effect. It illustrates how a force can cause a change in the body's rotational motion.
Torque is given by the formula :
α = r x F ( bold letters represent vector quantities)
The S.I. unit for torque is : N - m ( Newton - meter)
<h3>How do we define 1 N-m of torque?</h3>
The newton-metre is a torque unit (also known as a moment) in the SI system. The torque produced by a one newton force applied <u>perpendicularly to the end of a one metre long</u> moment arm is known as a newton-metre.

Explanation: Because mirrors are lighter, and they are easier than lenses to make perfectly smooth.

Answer:
B: Process #1: Energy is decreasing Process#2: Energy is increasing
Answer:
The speed in the smaller section is 
Explanation:
Assuming all the parts of the pipe are at the same height, we can use continuity equation for incompressible fluids:
(1)
With Q the flux of water that is 
with A the cross section area and v the velocity, so by (1):
subscript 2 is for the smaller section and 1 for the larger section, solving for 
:
(2)
The cross section areas of the pipe are:
but the problem states that the diameter decreases 86% so 
, using this on (2):
