Answer:
A) from the lowest to the highest frequency:
Microwave - infrared - ultraviolet- X-ray
B) from the highest to the lowest energy:
X-ray - ultraviolet - infrared - microwave
Explanation: electromagnetic spectrum is the range of all types of electromagnetic radiation.
Radiation is the energy that travels and spreads out as it goes out.

Answer:
23.889 Celcius
Explanation:
(75°F − 32) × 5/9 = 23.889°C
Explanation:
At the top of the tree, the velocity of the pebble is purely horizontal so we can calculate it as
Answer:
V is approximately = 23m/s
Explanation:
Kinetic energy = ½ mv²
Where m= mass = 0.450kg
V= velocity =?
K. E = 119J
Therefore
K. E = ½ mv²
Input values given
119= ½ × 0.450 × v²
Multiply both sides by 2
119 ×2 = 2 × 1/2 × 0.450 × v²
238= 0.450v²
Divide both sides by 0.450
238/0.450 = 0.450v²/0.450
v² = 528.89
Square root both sides
Sq rt v² = sq rt 528.89
V = 22.998m/s
V is approximately = 23m/s
