- At part A, Jay's motion can be described as <u>linear motion</u>.
- At part B, Jay's motion can be described as a <u>uniform motion</u>.
<h3>What is a motion?</h3>
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point, especially due to the action of an external force.
In Science, motion is described based on the following parameters:
Based on the graph that illustrates Jay's motion, we can deduce the following:
- At part A, Jay's motion can be described as <u>linear motion</u> because it is one-dimensional and it increased along a straight line.
- At part B, Jay's motion can be described as a <u>uniform motion</u> because it increased along a straight line at a constant velocity (speed).

Erosion, plate tectonics, and orbited celestial bodies (meteors etc.) <span />
That's false. It's the other way around. One light year is a distance that's a little farther than 63,000 astronomical units.
Answer: 0.512 kgm²
Explanation:
Given
Force, F = 2*10^3 N
Angular acceleration, α = 121 rad/s²
Lever arm, r(⊥) = 3.1 cm = 3.1*10^-2 m
τ = r(⊥) * F
Also,
τ = Iα
Using the first equation, we have
τ = r(⊥) * F
τ = 0.031 * 2*10^3
τ = 62 Nm
Now we calculate for the inertia using the second equation
τ = Iα, making I subject of formula, we have
I = τ / α, on substituting, we have
I = 62 / 121
I = 0.512 kgm²
Thus, the moment of inertia of the boxers forearm is 0.512 kgm²
Resistor X is the same material and thickness as resistor Y, but it is twice as long. The resistance of resistor X is double that of resistor Y.Option 2 is correct.
<h3>What is resistance?</h3>
Resistance is a type of opposition force due to which the flow of current is reduced in the material or wire. Resistance is the enemy of the flow of current.
The relation of the resistance with the length and thickness is;
For the given case;
Resistor X has the same thickness and is made of the same material as resistor Y but has twice the length. Resistor X has twice the resistance of resistor Y.
Hence,option 2 is correct.
