Answer:
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
Wavelength can be defined as the distance from one peak to the next peak. Also, this distance is equal to the distance from one trough of a wave to another.
Mathematically, the speed of a wave is given by the formula;
V = fλ
Where;
V is the speed of the wave.
f is the frequency of the wave.
λ is the wavelength of the wave.
The speed of a wave (wave speed) is directly proportional to the frequency of a wave.
This ultimately implies that, an increase in the speed of a wave would cause an increase in the frequency of a wave and vice-versa.
Answer :
The distance is 109.89 m.
Explanation :
Given that,
Height = 40 m
Angle = 20°
We need to calculate the base of the plateau
Using formula of angle
Where, h = height
x = base
= angle
Put the value into the formula
Hence, The distance is 109.89 m.

At Divergent boundary, Crust is created.
At Convergent boundary, Crust is destroyed.
At Transform boundary, Crust is neither created nor destroyed.
<h3>What occurs at Divergent, Convergent and Transform boundary?</h3>
A divergent boundary occurs when two tectonic plates move away from each other. At this boundary, new oceanic crust is created.
Convergent boundaries are those boundaries where two plates are pushing into each other. These boundaries are pushing one of the plates under the other and back into the mantle to melt.
Transform boundaries are places where plates slide sideways past each other. At this boundary, Crust is neither created nor destroyed.

Answer:
or 0.07163 T into the page
Explanation:
m = Mass of particle = 10 g
a = Acceleration due to gravity = -9.8j m/s²
v = Velocity of particle = 19i km/s
q = Charge of particle = 72 μC
B = Magnetic field
Here the magnetic and gravitational forces on the particle are applied in the opposite direction so,
The magnetic field is 0.07163 T into the page
