Hi there!
According to Newton's Second Law, force is calculated with the formula:
F = m × a, where:
F = force (N)
m = mass (kg)
a = acceleration (m/s²)
Velocity is the same as the formula for speed, the only difference is
velocity has direction. Velocity is distance over time. Given is 4,400
kilometers travelled west in 4 hours. Applying the given equation, we wil have
4,400/4 = 1,100 km/hr west
For the First answer, It would be "A"
The for the next one the answer is "C"
I hope this helps. :)
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.

Answer:
the displacement of the object is 5 units
Explanation:
The computation of the displacement of the object is shown below:
= Move to the right + move to the right - move to the left
= 6 units + 3 units - 4 units
= 9 units - 4 units
= 5 units
Hence, the displacement of the object is 5 units
