Internal combustion engine
The answer to your question will be C. because they are very inexpensive and are readily available but they will eventually deplete because we use them faster than they can be produced we use what has been building up.
From Snell's Law;
n₁sinθ₁ =n₂sinθ₂
Therefore; since the ray is travelling from ethanol to air, then n1 = 1.36 and
θ1 = 34, while n2= 1.00
(1.36) sin 34 = (1.00) sin θ₂
sin θ₂ = 0.7605
θ₂ = 49.50
≈ 49 °
The angle of refraction is therefore 49 degrees
Hello, use the formula:
Pe = mgh
Data:
Pe = Potential energy = ¿?
m = Mass = 48 kg
g = Gravity = 9,81 m/s²
h = Height = 7 m
Replacing according our data:
Pe = 48 kg * 9,81 m/s² * 7 m
Pe =3296,16 J
The potential energy of the skateboarder is 3296,16 Joules
