"Zero acceleration" means "velocity" that's not changing.
Sadly, it seems that both of these words are almost always
misinterpreted and misunderstood. "Acceleration" does NOT
mean "speeding up", and "velocity" does NOT mean speed.
"Velocity" is the speed AND direction of motion. So, for example,
'30 miles per hour north' and '30 miles per hour west' are the same
speed but different velocities.
"Acceleration" is ANY change in speed OR direction. Consider three
different families in three different cars. One car is speeding up, one is
slowing down, and the third is driving around a curve at a steady speed.
ALL three of the cars are accelerating.
time to reach an angular velocity of 36.8 is 24.370 s.
<h3>
</h3><h3>What is angular acceleration?</h3>
The temporal rate at which angular velocity changes is referred to as angular acceleration. Naturally, there are two forms of angular acceleration, referred to as spin angular acceleration and orbital angular acceleration, just as there are two types of angular velocity, namely spin angular velocity and orbital angular velocity. As opposed to orbital angular acceleration, which is the angular acceleration of a point particle around a fixed origin, spin angular acceleration describes the angular acceleration of a rigid body about its centre of rotation.
w(t) = w(0) + α*t
also w(0) =0
=> time = 36.8/1.51= 24.370 s

In case of an object sitting at rest on another base, there are two equal and opposite forces – Normal force and the gravity.
Answer: Option A
<u>Explanation:
</u>
When an object is placed at rest position on another object, there is a force exerted by the surfaces of the two contact objects. This force is denoted as Normal Force.
When an object such as a box is placed on a shelf, its surface exerts a contact force on the base of the shelf- The Normal force directed upward. Meanwhile, the gravity stays at its action and tries to pull the box towards itself.
Both of these forces however are equal and opposite and therefore, there is zero net force on the box. That's why it remains at rest, holding on Newton's third law.
The correct answer is total revenue minus total cost.
When a firm is calculating the profit they need to find the difference between how much money they earned and how much they spent. The difference between their total revenue and their total cost is their profit.
21N
Explanation:
Given parameters:
Mass of wagon = 14kg
Acceleration = 1.5m/s²
Unknown:
Net force on wagon = ?
Solution:
Force is a pull or push on a body that causes a body to change its state. It is expressed as:
Force = mass x acceleration
Force on wagon = 14 x 1.5 = 21N
