The point with the greatest potential energy is B.
The potential energy of an object is depends on the relative distance between the object and the ground and its mass. The higher the object is from the ground the greater the potential energy posses.
Potential energy (P.E) = mgh
Where m is the mass, g is the gravity and h is the height from the ground to where the object is.
Since the mass and gravity is constant in this case, only the height will determine the point with the greatest P.E and that point is B.
Answer:
Pressure = 320 N/m²
Explanation:
Given the following data;
Force = 8000 Newton
Area = 25 m²
To find the pressure, we would use the following formula;
Pressure = force/area
Substituting into the formula, we have;
Pressure = 8000/25
Pressure = 320 N/m²
Answer:
Explanation:
(C) 180 degrees, 90 degrees, 120 degrees.
A weight would be least affected since it would fall striaght down if it was say paper it would go down slower because it has more air resistance due to less weight
Answer:
a) λ = 0.5346 10⁻⁹ m, b) 1.13
Explanation:
a) The wave-particle duality is
λ = 
the expression for energy kinetic is
E = p² / 2m
energy is also related to temperature
E = 
we substitute
p =
λ =
Rubidium's mass is m = 85 uma
we calculate
λ =
λ=
λ = 0.5346 10⁻⁹ m
b) the relationship of the two lengths is
λ /0.47 nm = 0.53 / 0.47 = 1.13
