Speed of light relative to the boys = 300,000,000 m/s
Speed of light relative to a stationary observer on the side of the road =
<h3>300,000,000 m/s</h3><h3>What is special theory of relativity?</h3>
- The theory of special relativity explains how speed affects space, time, and mass.
- Small amounts of mass (m) can be interchangeable with large amounts of energy (E), as defined by the classic equation E = mc2, according to the theory, which offers a means for the speed of light to define the link between energy and matter.
<h3>What are the special relativity's guiding principles?</h3>
- The laws of physics should be independent of the uniform motion of an inertial frame of reference, and the speed of light should be constant in any such frame, according to two fundamental tenets that constitute the basis of the special theory of relativity.

The better health you have, the higher wellness you'll enjoy. Thus, the more exercise you do, the better fitness you'll have.
To make your formula neater:
Acceleration is equal to
,
so when you multiply it by time, you will get a velocity. In fact, you would get the change in velocity, as a*t signifies the acceleration of the object over the time, aka the change in velocity.
The initial velocity plus the change in velocity will equal the final velocity, irregardless if the change in velocity is positive or negative.
Therefore,
Answer:
degree
Explanation:
given data:
accoding to the snell's law
where n1 is refracting index of air = 1
n2 is refracting index of glass = 1.55
putting all value to get angle mad by incident ray with normal
degree
Static electricity is electricity produced locally that does not flow. It is produced by electrons being rubbed off one object and collecting on another. It cannot flow through a wire like the electricity in your home.
Example:
1) Rub a balloon on your hair and it will stick to the wall. The balloon rubs electrons off your hair and picks up a negative charge. Your hair, in turn, is left with a positive charge. You may even notice your hair has "static" and is standing out from your head.
2) Comb your hair with a plastic comb then use it to pick up small pieces of paper. The comb picks up electrons from your hair and becomes negatively charged. It uses this charge to attract the pieces of paper.
3) Rub your slippered feet on the carpet and then touch something metal like a door knob. The "shock" you feel is static electricity. You pick up electrons from the carpet and discharge them on to the door knob.
