The main difference between a radio wave and a light wave is its:.
Answer:
Speed.
Their speeds are different; Have you ever heard the metaphor the speed of light? For this case, we must turn that into a reality. So, people refer to light speed as the fastest travelling thing in the world, and that is right, unless there is a thing faster than light that was never classified. Unlikely the case. The speed of sound through air travels a lot slower than light. Look at the diagrams below to see what I mean by that.

If the pressure exerted by the liquid of density 500kg/m3 is 20,000Pa. What is height of liquid column.
The height of the liquid column is 4.08 metres.
The peak of the liquid column is 4.08 metres.
What's strain exerted with the aid of a liquid?As we realize that any liquid exerts a strain at a factor relies upon on the density of the liquid and the vertical intensity. depth is given = h and the acceleration because of gravity is g.
calculation:-
pressure = ρgh
ρ = density of the liquid
g = accaleration due to gravity
h = depth from the surface
l = 500kg/m3
p = 20,000
g = 9.8 ms-2
20,000Pa= 500*9.8*h
h=4.08m
What's the stress density?The stress is the measure of pressure acting on a unit region. Density is the measure of the way intently any given entity is packed, or it is the ratio of the mass of the entity to its extent. The relation between strain and density is direct. exchange in stress will be contemplated in a exchange in density and vice-versa.

Sometimes, supplies can be delivered to people in remote areas by dropping them off from a plane. This is usually the case for ground troops working in areas where planes are unable to land safely. Parachutes are attached to boxes to prevent damage to items when they land. Compare the parachute setups in the image; A has three parachutes attached, B has one parachute attached, and C has two parachutes attached. If every parachute in all three setups are the same size, and each setup was attached to a 50-pound box, which lists the order the boxes would land from slowest to quickest?
A) A, B, C
B) B, C, A
C) А,С, В
D) В, А, С
The order the boxes would land from slowest to quickest is A,C,B which is option C.
What is a Parachute?This is a device used to slow the motion of an object through an atmosphere by creating drag.
The size of the parachute affects the speed of falling because a larger parachute allows it to displace more air, causing it to fall more slowly. The one with three parachutes which is A will fall slowest and the one with just one will fall fastest.

An inductor produces a back emf in a dc series rl circuit when a switch connecting the battery to the circuit is closed. We can explain this by.
Hi there!
Let's say that a series RL circuit is constructed, with the switch left open.
When the switch is closed, a current will start flowing in the circuit. The INCREASING current will go through the loops of the inductor, producing an INCREASING magnetic field and consequentially a magnetic flux through the inductor. (Use hand rules).
However, the inductor does NOT want to experience this increasing magnetic flux, so an emf in the OPPOSITE direction of the current will be produced to counteract the increasing flux. (The flux would also be in the opposite direction).
This is expressed with the equation:
[tex]\epsilon = -L \frac{di}{dt}[/tex]
ε = Back emf (V)
L = Inductance (H)
i = Current (A)
t = time (s)
With the negative sign, we can see that if the current of the circuit is INCREASING, the emf produced would be in the opposite direction.
