Momentum = mass x velocity
= (1200)(25)
Momentum = 30,000 kg m/sec
hope this helps :)
Answer:
The statement that offers a hypothesis on how people’s backgrounds and interests influence their work is that a person’s background and interests can give him a unique perspective in his research. The correct option is B.
Explanation: Alot of scientist has contributed one way or the other in the model of atoms and this was soo because of their background and interests which gave them a unique perspective in the study of the model of atoms. For example John Dalton who was known to propose the atomic theory, studied chemistry( he had a strong background in knowledge of chemistry) and he had interest in the study of the physical properties of the atmosphere and other gases. This gave him a unique perspective in his research works.
Answer:
Wave speed = 1.25 m/s
Explanation:
Given that the
wavelength = 0.25 m.
Frequency F = 5.0 Hz
The speed of a wave is the product of wave frequency and the wavelength. That is
V = F λ
Where
V = wave speed (m/s)
λ = wavelength (m).
F = frequency (Hz).
Using the formula above gives:
V = 0.25 × 5
V = 1.25 m/s
