Answer:
Hope this helps
Explanation:
As we know our atmosphere or air have different levels. Every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
Answer:
17 * 10^5 J
Explanation:
From;
H= mcΘ
where;
m = mass of water = 5.0 Kg
c = heat capacity of water = 4 200 J/Kg °C
Θ = temperature rise = 100 °C - 20 °C = 80°C
Substituting values;
H = 5 * 4 200 * 80
H = 17 * 10^5 J
The transformation is kinetic energy
Answer:
20m/s
Explanation:
Given parameters:
Distance of throw = 50m
Time = 3s
Unknown:
Average speed = ?
Solution:
Average speed is distance divided by time;
Average speed = 
Insert the parameters and solve;
Average speed = 
= 16.66667m/s = 20m/s
