The wavelengths of terrestrial radiation from earth's surface are concentrated in thermal infrared spectrum.

<u>Explanation:</u>

The wavelengths used in thermal infrared are in the range of micrometer ranging from 8 to 15. Terrestrial radiation is defined as the radiation that is originating from earth due to radioactive materials like uranium, thorium e.t.c.

Increase in terrestrial radiation by the use of radioactive materials will consequently increase global warming as it releases green house gases thereby degrading the quality of earth's atmosphere.

Imagine you could travel to the moon where the acceleration due to gravity is 1.6 m/s^2. What would be the period of

VladimirAG [237]

Answer:

4.9612 s

Explanation:

Applying,

T = 2π√(L/g)............... Equation 1

Where T = period of the pendulum, L = Lenght of the pendulum, g = acceleration due to gravity of the moon, π = pie.

From the question,

Given: L = 1 m, g = 1.6 m/s²

Constant: π = 3.14

Substitute these values into equation 1

T = 2×3.14×√(1/1.6)

T = 6.28√(0.625)

T = 6.28×0.79

T = 4.9612 s

man stands on a platform that is rotating (without friction) with an angular speed of 1.2 rev/s; his arms are outstretched and h

-Dominant- [34]

Answer:

w₂ = 22.6 rad/s

Explanation:

This exercise the system is formed by platform, man and bricks; For this system, when the bricks are released, the forces are internal, so the kinetic moment is conserved.

Let's write the moment two moments

initial instant. Before releasing bricks

L₀ = I₁ w₁

final moment. After releasing the bricks

$L_{f}$ = I₂W₂

L₀ = L_{f}

I₁ w₁ = I₂ w₂

w₂ = I₁ / I₂ w₁

let's reduce the data to the SI system

w₁ = 1.2 rev / s (2π rad / 1rev) = 7.54 rad / s

let's calculate

w₂ = 6.0/2.0 7.54

w₂ = 22.6 rad/s

How is newtons third law of motion demonstrated on a roller coaster?

butalik [34]

<span>Newton's Third Law of Action-Reaction is that for each and every action that happens, there is an equal and opposite reaction to it. In the scenario of a roller coaster, this is when you push down on the seat of the roller coaster as it flies along and the seat pushes back against you.</span>
