Answer:
Option C. Rate of change of velocity
Explanation:
To know the correct answer to the question, it is important we know the definition of power.
Power can be defined as the rate at which work is done. Mathematically, it is expressed as:
Power = work / time
Work and energy has the same unit of measurement i.e joule. Thus, power can also be defined as the rate at which energy is transferred i.e
Power = enery / time
Energy is measured in Joules and time in second. Thus, power can also be defined as amount of joules transfered per second.
Power = Joule / sec
The rate of change of velocity on the other hand is termed acceleration.
Thus, the answer to the question is option C.
Answer:
80.386 degrees
Explanation:
We use the cosine equation here (which is the adjacent side of the unknown angle divided by the hypotenuse
The adjacent side = 699ft
The hypotenuse = 1034ft
using cos∅ = Adjacent/hypotenuse
where ∅ is the unknown angle
cos ∅ = 699/1034 = 0.167
∅ = arccos 0.167 = 80.368°
As easy as one can imagine

C) 4x10^7 m/s
D) 20 m
E) 9.09x10^-8 sec
F) 9.09x10^-8 sec
Explanation:
Detailed explanation and calculation is shown in the image below
-- Whether an object floats or sinks in water depends on whether its density is more or less than the density of water.
-- The density of the rock didn't change when she threw it into the lake.
-- The density of the water didn't change when she threw the rock into the lake.
-- The density of anything never depends on how much of it you have.
-- If the rock sank in two ounces of water, it'll sink in a billion gallons of water.
-- Choose ' <em>A </em>' .
Answer:
The relativistic speed of a particle is 
Explanation:
Given that,
Time = 6 sec
Force = 1
Mass of the particle 
We need to calculate the acceleration
Using formula of acceleration

Put the value into the formula


We need to calculate the velocity after 6 sec
Using equation of motion

Put the value


The velocity in term of c



Hence, The relativistic speed of a particle is
