Answer:
2 × 10⁸J/kg
Explanation:
Specific latent heat of vaporization (steam) is the quantity of heat required or needed to change a unit of mass of liquid to gaseous state at constant temperature (boiling point) and pressure.
It can be calculated mathematically using,
Q = mL
Where, Q = quantity of heat
m= mass in kg
L = specific latent heat (J/kg)
Therefore,from the question
Q= 15000000J
mass (m) = 75g = 75/1000 kg = 0.075kg
Q = mL
L = Q/m
L = 15000000 ÷ 0.075
L= 200000000J/kg
L = 2 × 10⁸J/kg

Answer:
A continuous flow of negative charges (electrons) creates an electric current. The pathway taken by a electric current is a circuit.
Explanation:
Answer: because of the magnetic
Explanation: If you hold a compass near a wire through which current is flowing, the needle on the compass will be deflected. Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing.
