The two regions of the electromagnetic spectrum where the Earth's atmosphere is transparent are visible light and some radio waves.
<h3>What is electromagnetic spectrum?</h3>
The electromagnetic spectrum consists of the range of all types of EM radiation. Radiation is packet of energy that travels and spreads out. It has radio waves, infrared waves, visible light waves, ultraviolet rays and microwaves.
They possess high energy even to penetrate deep within the material. The electromagnetic spectrum has longer wavelength and less frequency.
Thus, the two regions of the electromagnetic spectrum where the Earth's atmosphere is transparent are visible light and some radio waves.

A scale can be used to measure miligrams,centigrams,grams and small numbers
Answer:
0.01154 A
Explanation:
We have given the energy in the magnetic field 
Value of inductance L =0.060 H
Energy stored in magnetic field is given by 
So the current flowing through rectangular toroid will be 0.01154 A
Answer:
the runner's average kinetic energy during the run is 476.96 J.
Explanation:
Given;
mass of the runner, m = 85 kg
distance covered by the runner, d = 42.2 km = 42,200 m
time to complete the race, t = 3 hours 30 mins = (3 x 3600s) + (30 x 60s)
= 12,600 s
The speed of the runner, v = d/t
v = 42,200 / 12,600
v = 3.35 m/s
The runner's average kinetic energy during the run is calculated as;
K.E = ¹/₂mv²
K.E = ¹/₂ × 85 × (3.35)²
K.E = 476.96 J
Therefore, the runner's average kinetic energy during the run is 476.96 J.
Answer:
2.53 cm³
Explanation:
Volume of cylinder = πr²h; where h is the height and r is the radius and
π = 3.14 approx.
Volume = 3.14 * (1.55/2)² * 1.34 = 2.53 cm³
I divided 1.55 by 2 because we were given the diameter and not radius. Diameter = radius / 2
