If millikan was measuring the charge on an oil droplet with 3 negatively charged electrons on it, what charge would he have meas
Korvikt [17]
The unit of measurement for charge is Coulomb. Now, every particle of electron contains a charge equal to 1.602×10⁻¹⁹ <span>C. So if there are 3 electrons in the oil droplet, then the total charge would be:

Total charge = 3 electrons(</span>1.602×10⁻¹⁹ C/ electron)
Total charge = 4.806×10⁻¹⁹ C

How much energy is needed to heat and melt 3.0 kg of copper initially at 83°C?
Ne4ueva [31]

As we know that in order to melt the copper we need to take the temperature of copper to its melting point

So here heat required to raise the temperature of copper is given as

Q = ms\Delta T

We know that

melting temperature of copper = 1085 degree C

Specific heat capacity of copper = 385 J/kg C

now we have

Q = 3(385)(1085 - 83)

Q = 1157310 J

Q = 1157.3 kJ

now in order to melt the copper we know the heat required is

Q = mL

here we know that

L = 205 kJ/kg

now from above formula

Q = 3(205) kJ

Q = 615 kJ

now total heat required will be

Q = 1157.3 kJ + 615 kJ

Q = 1772.3 kJ

As we know that

1 Cal = 4.18 kJ

now we have

Q = \frac{1772.3}{4.18} = 430 KCal
