Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence/omission of the wavelength but the completed question is attached below.
The formula for frequency is f = c/λ
where f is the frequency (unknown)
c is the speed of light (3.0 × 10⁸ m/s)
λ is the wavelength (599 nm)
f = (3 × 10⁸) ÷ 599
f = 500834.73 Hz or 5 × 10⁵ Hz
Answer:
The box with a mass of 10 kilograms would have a greater amount of potential energy than the box with a mass of 4 kilograms.
Explanation:
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Let's assume the height is 5 meters.
Acceleration due to gravity, g = 10 m/s²
For box with mass of 10 kg
P.E = 500 Joules.
For box with mass of 4 kg;
P.E = 200 Joules.
Hence, the box with a mass of 10 kilograms would have a greater amount of potential energy than the box with a mass of 4 kilograms.
