Always in the form of heat energy
Answer and Explanation:
with reference to Einstein's theory of special relativity, the speed of an electromagnetic radiation, here, laser will not change in any inertial frame or remains same irrespective of any change in inertial frame.
Therefore, the speed of light measured in both the cases, i.e., in astronaut's reference frame and spaceship's reference frame will be equal to the speed of light in vacuum, i.e.,
.
The laser gun's speed in astronaut's reference frame is the same as the speed of the spaceship as it mounted on it, i.e., the speed of the laser gun is 200 million m/s.
The laser gun's speed measured in spaceship's reference frame will be zero, as it is mounted on the spaceship and is stationary in the spaceship's reference frame.
The electromagnetic wave shown above is made up of vibrating Electric fields.
I assume this is why electromagnetic waves can travel through a vacuum, due to lack of matter.
Answer:
5N
Explanation:
Data obtained from the question include:
K (spring constant) = 20N/m
e (extension/compression) = 0.25 m
F (force) =?
Using the formula F = Ke, the force can be obtained as follow:
F = Ke
F = 20 x 0.25
F = 5N
Answer:
Explanation:
Given
Electric Field Strength 
Potential Difference between Plates is given by 
In conducting plates a Potential difference exist between two plate which accelerate the charge when put between the conducting plates
The potential difference is given by

where E=Electric Field strength
d=distance between Plates
