The heat energy required is 2983 J
Explanation:
When an amount of energy Q is supplied to a certain sample of substance of mass m, the temperature of the substance increases by an amount of
according to the equation
:
where
Q is the heat supplied
m is the mass of the object
is the specific heat capacity of the substance
is the change in temperature
For the glass bottle in this problem:

is the change in temperature
is the specific heat of glass
Substituting into the equation, we find

Each object exerts a force equal to and in the opposite direction of the other.
Answer:
<em>F=8.87 N</em>
Explanation:
<u>Coulomb's Law
</u>
The electrostatic force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.
Written as a formula:

Where:

q1, q2 = the objects' charge in coulomb
d= The distance between the objects in meters
Object 1 has a charge of

Object 2 has a charge of

They are separated by a distance of
d = 0.099 m
Calculate the force:

F=8.87 N
Answer:
the driving gear must be larger than the driven gear
