It hasn't moved from its original spot so displacement is 0
Answer:
ground
Explanation:a conductor connected directly to the earth is called a ground
All of these things were seen in formal experiments by the 19th century. But some of them are easy to see in your own home. It's obvious that light can reflect - you just have to look in a mirror. Light bounces off the mirror and goes into your eye so you can see yourself. It's also obvious that light can refract: All you have to do is put a spoon in a large glass of water and watch how the spoon appears to bend.
That happens because the light is bending as it moves between air and water. Both of these things can be seen even more clearly in a laboratory using beams of light or lasers.
Answer:ok yes
Explanation:yes of course
Answer:
The strength of the electric field is 
.
Explanation:
Given that,
Speed 
Time 
Angle = 45°
We need to calculate the acceleration
Using equation of motion
We need to calculate the strength of the electric field
Using relation of newton's second law and electric force
Put the value into the formula
Hence, The strength of the electric field is .
