Explanation:
To solve the problem for time you will have to use the formula for time, t = d/s which means time equals distance divided by speed.
Kindly check the attached image below for the step by step explanation to the question.
Explanation:
I don't know what values you have measured, or what <em>Ladybug Revolution</em> is, but I can show you the equations for rotational motion.
Angular displacement is:
Δθ = ω₀ t + ½ αt²
where ω₀ is the initial angular velocity, α is the angular acceleration, and t is time.
Assuming the radius is constant, the arc length is radius times angular displacement.
s = rΔθ
Using the equation for angular displacement, we can see that if two points have the same angular velocity and same angular acceleration, then they also have the same angular displacement.

Hello! Here are your answers!
SCALAR: Scalar quantities have a size or magnitude only.
VECTOR: Vector quantities have both magnitudes and direction.
Explanation:
They are alike as they are both used to explain physical quantities and represent the magnitudes or sizes of the physical quantities...
They are different as VECTOR quantities describe an objects DIRECTION as well as magnitude whilst SCALAR doesn't
ie...<u>SCALAR:</u> MASS, TIME
<u>VECTOR:</u> VELOCITY, ACCELERATION...
I HOPE THIS HELPS!!
Answer:
d. 100.0 J
Explanation:
To solve this problem we must use the theorem of work and energy conservation. This tells us that the mechanical energy in the final state is equal to the mechanical energy in the initial state plus the work done on a body. In this way we come to the following equation:
E₁ + W₁₋₂ = E₂
where:
E₁ = mechanical energy at state 1. [J] (units of Joules)
E₂ = mechanical energy at state 2. [J]
W₁₋₂ = work done from 1 to 2 [J]
We have to remember that mechanical energy is defined as the sum of potential energy plus kinetic energy.
The energy in the initial state is zero, since there is no movement of the hockey puck before imparting force. E₁ = 0.
The Work on the hockey puck is equal to:
W₁₋₂ = 100 [J]
100 = E₂
Since the ice rink is horizontal there is no potential energy, there is only kinetic energy
Ek = 100 [J]
It can be said that the work applied on the hockey puck turns into kinetic energy
When cattle are processed, the most likely use for the animals' skin is in
the production of Leather.
<h3 /><h3>Animals used for Leather production</h3>
The commonly used animals in leather production is however cattle and
they amount for a large percentage of leather present today. They also
involve various techniques such as tanning and crusting to ensure
conversion to leather.
