Answer:
A. Moving the mass from Point C to B, although it involves a greater distance, requires less force to do the same amount of work.
Explanation:
The amount of work will be the same either way. By going from C to B, the mover will exert less force over a greater distance, which is easier than exerting a greater force over a shorter distance.
A. Blocking light waves that vibrate in the plane. (?)
The statement that is true concerning an atom would be C. The atomic number of an atom is equal to the number of protons.
The order for the scientific method is
1. Ask a question
2. Form a hypothesis as an if, then statement (If the liquid is blue, then it must be water)
3. Conduct an experiment
4. Collect the observations
5. Analyze the data
6. Draw a conclusion using while restarting your hypothesis
Answer: 0.4m
Explanation:
Given that:
Amplitude of wave = 2.0 m
Wavelength (λ)= ?
Frequency F = 500Hz
Speed V = 200 m/s
The wavelength is measured in metres, and represented by the symbol λ.
So, apply the formula:
Wavespeed V= Frequency F xwavelength λ
200m/s = 500Hz x λ
λ = 200m/s / 500Hz
λ = 0.4m
Thus, the wavelength is 0.4 metres
