The negative charge distribution that surrounds the nucleus of an atom is due to the atom's electron cloud. As the electrons move around a molecule, it can make a certain position, for an instant, look negative when the electrons are on one side and when they are away from this side it can look positive. This can cause intermolecular attraction and is known as the London Dispersion force of attraction.
Observations is the answer.
Answer:
The average velocity of the motor cycle in m/s = 20 m/s
Explanation:
Given;
average velocity of the motor cycle, v = 72 km/h
time of motion, t = 20 s
The average velocity is already given in the question, the time in the question is irrelevant.
You can also convert the 72 km/h to m/s by dividing by 3.6 km/h
Thus, 72 km/h divided by 3.6 km/h = 72 / 3.6 = 20 m/s
Therefore, the average velocity of the motor cycle in m/s = 20 m/s
Answer:
a. xy
Explanation:
The Faraday's law of induction can be used to express the relationship between the electric field line integral and the magnetic flux rate change in a closed loop. In order to ensure that the relationship between the two variables is equivalent to zero, the integration should be conducted on the xy plane. The correct option is option a.
