- 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

Objects have the same terminal velocity as they do when they is air so option A is correct
Answer: Option (b) is the correct answer.
Explanation:
Kinetic energy is defined as the energy obtained by a substance due to its motion. So, when an electron or substance is moving from one point to another then the electron has acquired a motion.
Hence, this means that the electron has acquired kinetic energy.
For example, when an electron jumps from the negative to the positive terminal then it means the electron is moving. Hence, it has obtained a motion.
Thus, we can conclude that as the electron jumps from the negative to the positive terminal as the electron jumps from the negative to the positive terminal.
