- Pressure = 5000 Pa
- Contact Area = 0.04 m^2
- Acceleration due to gravity = 9.8 m/s^2
- Let the force be F.
- We know, Force = Pressure × Contact Area
- Therefore, Force = 5000 Pa × 0.04 m/s^2
- or, Force = 200 N
- We know, force = mass × acceleration
- Therefore, mass = force ÷ acceleration
- or, mass = 200 N ÷ 9.8 m/s^2 = 20.4 Kg

Answer:
Solar energy - Chemical energy - Electrical energy
Explanation:
A photovoltaic is a device which operates with respect to its exposure to radiation or light. This property determines its applications in electronics.
The energy from sunlight is in the form of solar energy, which get absorbed by the photovoltaic cell. The cell transforms the solar energy and store it as chemical energy. This is now finally transformed majorly into electrical energy as the output energy from the cell. Some amount of heat energy is produced in the process.
