<u>Answer:</u>
Specific Heat
<u>Explanation:</u>
Specific heat is the measurement which describes the amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.
It is the amount of heat required per unit mass to raise the temperature by one degree Celsius. The relationship between heat and the temperature change is usually expressed as shown below:
Δ
where
= heat added,
= specific heat,
=mass; and
Δ
= change in temperature
To solve this problem it is necessary to apply the concepts related to Newton's second law and its derived expressions for angular and linear movements.
Our values are given by,

If we carry out summation of Torques on the pulley we will have to,

Where,
I = Inertia moment
Angular acceleration, which is equal in linear terms to a/r (acceleration and radius)
The moment of inertia for this object is given as

Replacing this equations we have know that



Or

Replacing our values we have that


Therefore the tension in the string between the pulley and the cart is 0.974 N
To be honest, the picture is so far above that I can't see it at all.
But reading the information in the question's statement, I'd say
the blank should be filled in so that it says:
<span> The chemical energy in the battery is used to light up the light bulb
on the other end. Chemical energy in the battery is transformed into
electrical energy which runs through the circuit wire. (A)</span>
A car with a velocity of 22 m/s is accelerated at a rate of 1.6
for 6.8s has the final velocity t be 32.88 m/s.
The acceleration means the amount of velocity changing per unit time.
The given data:
initial velocity, u = 22 m/s
time, t = 6.8 s
acceleration, a = 1.6 
We will be using the equation of motion:
v = u + at



The final velocity become 32.88 m/s.

As we know that Nth harmonic of the string is given by

now here we will have




now from above formula we have


now for first harmonic N = 1

for second harmonic N = 2

for third harmonic N = 3
