The process you're fishing for is "polarization", but that's a
misleading description.
Polarization doesn't do anything to change the light waves.
It simply filters out (absorbs, as with a polarizing filter) the
light waves that aren't vibrating in the desired plane, and
allows only those that are to pass.
The intensity of a light beam is always reduced after
polarizing it, because much (most) of the original light
has been removed.
A laser light source may be thought of as an exception,
since everything coming out of the laser is polarized.
Answer:
t = 0.319 s
Explanation:
With the sudden movement of the athlete a pulse is formed that takes time to move along the rope, the speed of the rope is given by
v = √T/λ
Linear density is
λ = m / L
λ = 4/20
λ = 0.2 kg / m
The tension in the rope is equal to the athlete's weight, suppose it has a mass of m = 80 kg
T = W = mg
T = 80 9.8
T = 784 N
The pulse rate is
v = √(784 / 0.2)
v = 62.6 m / s
The time it takes to reach the hook can be searched with kinematics
v = x / t
t = x / v
t = 20 / 62.6
t = 0.319 s
Answer:
the optic nerve
Explanation:
auditory, rods, and cones i think are to the ear.
optic means eyes, and nerves connect to the brain
Answer:
F=ma is the relationship where, F is force, m is mass and a is acceleration.
Newton's second law states that the unbalanced force applied to the object accelerates the object which is directly proportional to the force and inversely to the mass.
If we apply force to a toy car then It will accelerate.
This is how Newton's second law of motion is verified.
Th answer is it could gain or loss magnetism.
Ferromagnetism is a kind of magnetism that is associated with cobalt, iron, and nickel and on some alloys or compounds containing one or more of the said elements, It also occurs in gadolinium, which is a rare-earth element. In comparison to other substances, ferromagnetic materials can be magnetized easily and in strong magnetic fields, the magnetization approaches a definite limit called stauration.
If an external field is applied and subsequently removed which does not return the magnetization to its original state or value it is called hysteresis. When heated to a certain temperature (Curie point), which is unique for each substance, ferromagnetic materials would somehow lose their magnetic properties and cease to be magnetic. Once they would cool down, their magnetism would return.
