Answer:
Explanation:
Given,
Magnetic field
Radius
The angle between the area vector and magnetic field is 0 degree, because the direction of area vector is always perpendicular to the plane.
We are given an electromagnetic wave with a frequency of 5.09 x 10^14 Hz and travelling through a transparent medium. If the medium was vacuum, the speed of the wave would be equal to the speed of light. Otherwise, the main factor that would determine the speed of the wave is its wavelength.
Explanation:
We have,
Electric field intensity is 700 N/Cj
It is required to find the magnitude and direction of the acceleration of this electron due to this field.
The electric force is balanced by the force due to its motion i.e.
qE =ma
a is acceleration of this electron
So, the acceleration of the electron is and it is moving in +y direction.
If <em>v</em> is the truck's final velocity, then
<em>v</em>² - (2.0 m/s)² = 2 * (2.00 m/s²) * (400.0 m)
<em>v</em>² = 1604 m²/s²
<em>v</em> = 40.05 m/s ≈ 40 m/s
