Gamma rays because it is a form of electromagnetic radiation. It has zero mass and no charge.
When a motorboat passes by, a disturbance or vibration in the lake water is created which travels in all the directions. A water wave is a combination of longitudinal wave as well as transverse wave. If you are a particle of water in the lake, then you would be hit by nearby water particle which would set you in motion. you would travel up and down forming crest and trough and sideways. The energy would be transported forward, as you would collide with other particle and the wave moves forward. your position would not change. only the energy would be transported.
Answer: Both masses are 0.285 m apart
Explanation:
According to the law of Universal Gravitation:
Where:
is the gravitational force between the masses
is the gravitational constant
is the mass of the first object
is the mass of the second object
is the distance between the objects
Isolating :
This is the distance between both objects
Answer:
The total distance is equal to the change in total position of the person, but the displacement of the person is zero.
Explanation:
- The distance is the total change in the positions of the toy robot. it is having only magnitude and it is a scalar quantity.
- The displacement is the difference between the final and initial position of the toy robot. it is a vector quantity having magnitude and direction
- Since the distance is the change in positions, so the magnitude of the distance will be equal to the up and down distance covered.
- If the toy robot travels in a straight line path and returns back to its original location, the magnitude of the distance and displacement doesn't depend on the speed of the toy robot.
Note : Be careful with speed and velocity, even the formula is same that
1. If we would like to find the velocity, we must calculate the distance from initial to final,
,
2. If we would like to find the speed, we must calculate the total distance that travelled (
.
So, in this question, because it return back to its initial point so (delta)x = 0, so average velocity is 0 m/s.
