Answer:

Explanation:

To find the force between the two charges, we required the charges on each object and the distance between the two objects.

In the question, the distance between two charges is not given so we cannot find the charge on each sphere.

If the force is attractive, then the charges are opposite in nature and if the force is repulsive then the charges are same in nature.

You then measure Polly's internal temperature to be 13oC, which is quite a drop from the normal human body temperature of 37oC.
ankoles [38]

Answer:

The specific heat is 3.47222 J/kg°C.

Explanation:

Given that,

Temperature = 13°C

Temperature = 37°C

Mass = 60 Kg

Energy = 5000 J

We need to calculate the specific heat

Using formula of energy

Q= mc\Delta T

c =\dfrac{Q}{m\Delta T}

Put the value into the formula

c=\dfrac{5000}{60\times(37-13)}

c=3.47222\ J/kg^{\circ}C

Hence, The specific heat is 3.47222 J/kg°C.
