Physics is a branch of science that deals with the properties of matter and energy and relationship between them it also tries to explain the material world of the natural phenomenon of the universe the scope of physics is very wide and vast
Answer:
A) Light waves are restricted to a single plane through the lens.
Explanation:
Took the quiz and got it right
Answer:
Explanation:
Initial velocity, u = 85 m/s
Final velocity, v = 45 m/s
Time, t = 4.5 s
We need to find the acceleration of the dragster. The rate at which the velocity of an object changes is called the acceleration of an object. It can be given by :
So, the acceleration of the dragster is and it is deaccelerating.
6.6 * V/m is the electric field amplitude of an electromagnetic wave whose magnetic field amplitude is 2.20 mT
<h3>Given the data in the question:</h3>
Magnetic field amplitude = Bm = 2.20 mT = 2* T
Electric field amplitude = Em = ?
<h3>Electric field:</h3>
An electric field is a field created by electrically charged particles that attracts or repels other electrically charged particles surrounding it.
The greatest strength of the electric and magnetic fields is known as the electric field amplitude.
It can be said to be,
Em = c * Bm
Where, c is the speed of light(c = 3 * m/s)
Bm is the magnetic field amplitude
On substituting the values we get,
Em = c * Bm
Em = 3 * m/s * 2.20 * T
Em = 660000 V/m
Em = 6.6 * V/m
