Answer:
Explanation:
By energy conservation we know that spring energy is converted into kinetic energy of the block
so we will have
so we will have
now we will have same thing for another mass 4m which moves out with speed 5v
so we have
now from above two equations we have
so we have

Explanation:
Answer:
The wavelength is 4.55 m.
Explanation:
Given data
- Frequency (ν): 66.0 MHz = 66.0 × 10⁶ Hz = 66.0 × 10⁶ s⁻¹
- Speed of light (c): 3.00 × 10⁸ m/s
- Wavelength (λ): To be found
We can determine the wavelength of the radio waves using the following expression.
c = λ × ν
λ = c / ν
λ = (3.00 × 10⁸ m/s)/66.0 × 10⁶ s⁻¹
λ = 4.55 m
