Answer:
Newton Second
Explanation:
The SI unit of impulse in Newton Second (N.s)
First let's convert the time in seconds:
The current is defined as the quantity of charge flowing through a certain section of a circuit per unit of time:
Using I=10 A, and
, we can find the amount of charge flown through the hair dryer in this time:
The charge of a single electron is
, so the number of electrons flown through the hair dryer is the total charge divided by the charge of a single electron:
There are three main factors that affect wave formation: wind velocity, fetch, and duration.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
5 minutes is the minimum time
Answer:
Because the force is inversely proportional to the square of the distance
Explanation:
The magnitude of the electrostatic force between two charged particles is given by
where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
d is the distance between the two charges
We observe that the magnitude of the force is inversely proportional to the square of the distance.
Therefore, when the distance changes to
The force will double:
