Hello! My name is Zalgo and I shall be helping you out on this mystical day~! The answer that you are looking for is... "In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force. It is calculated by the formula W = f x d. Therefore, we calculate the problem above as follows:
W = f x d
4000 = f x 20
f = 200 N"
I hope this answer helps! :P

Answer:
On removal to the glass rod the leaves of the electroscope will disperse away under the influence of the positive charge due to deficiency of electrons.
Explanation:
When a glass rod is rubbed against a nylon then the electrons from the surface of the glass rod get transferred to the nylon piece and as a result the glass rod attains positive electrostatic charge.
When this positively charged rod is brought close to the knob of an electroscope then the electrons from that metallic of the electroscope feel attraction and move toward the glass rod get concentrated on the knob.
- In this situation when any of our body part comes in direct contact to the knob these static concentrated charges get a path to flow from high concentration to a lower concentration under the influence of the electrostatic force of the rod.
- So these charges flow into our body from the knob.
- Our body acts as a reservoir for the charges on the metallic knob.
- Now after the electrons form the knob are transferred to the person's body the electroscope becomes electron deficient and hence positively charged.
- So now, on removal to the glass rod the leaves of the electroscope will disperse away under the influence of the positive charge.
Answer:
Power = 251.9 Watts
Explanation:
Power = Work Done / Time taken
Power = 3441 / 13.66
Power = 251.9 Joule / Second
Power = 251.9 Watts
water management, carbon dioxide, sunlight, or water
