Answer:
Both particle and wave properties
Explanation:
Light is defined as a particle and a wave, and even as a combination of a particle and a wave. A unit of light is the photon. Higher energy photons behave like particles and low energy photons behave like waves.
Experiments performed with light indicate that light exhibits both particle and wave properties.
Average velocity is the ratio of the total distance travelled to the total time spent.
Instantaneous velocity is the average velocity a body as the time tends to zero
Answer:
(a)
(b) The force is repulsive
Explanation:
a) According to Coulomb's law, the magnitude of the electrice force that one particle exerts on the other is defined as:
Here k is the coulomb constant, and are the signed magnitudes of the charges and d is the distance between them.
b) According to Coulomb's law, if the two charges have the same sign, the electrostatic force between them is repulsive.
Answer:
Yes it is related
Explanation:
Consider 2 points in a rectangular co-ordinate system
The distance between them can be found by
d =
This is clear from the figure attached below
Answer:
0.13 km/s²
Explanation:
Convert hours to seconds
1 hour = 60 seconds (60) = 3600 seconds
= 0.052778
= 0.013195
0.13 km/s^2 (Round the three decimals)
