Answer:
λ = 3.33 m
Explanation:
<u><em>Given:</em></u>
Frequency = f = 9 × 10⁷ Hz
Speed = v = 3 × 10⁸ m/s
<u><em>Required:</em></u>
Wavelength = λ = ?
<u><em>Formula:</em></u>
v = fλ
<u><em>Solution:</em></u>
<em>Putting the givens in the formula</em>
v = fλ
λ =
λ =
λ = 0.33 × 10¹
λ = 3.33 m
Answer:
The electric field is
Explanation:
From the question we are told that
The peak magnitude of the magnetic field is
Generally the peak magnitude of the electric field is mathematically represented as
Where c is the speed of light with value
So
Answer: the force increases as the angle increases
Explanation:
If we assume the incline plane is frictionless, the only force acting on an object on the incline plane is the force of gravity:
where m is the mass and g the acceleration due to gravity.
However, the actual force that makes the object sliding down along the incline is not the gravity itself, but the component of the force of gravity parallel to the surface of the incline, which is given by
where is the angle of the incline.
Therefore, we see that as the angle of the incline increases, the force on the object increases.
