Answer:
-2000 N
Explanation:
To solve the problem, we can use the impulse theorem, which states that the impulse is equal to the change in momentum of the car:
where
F is the average breaking force
is the stopping time
m = 1000 kg is the mass of the car
is the change in velocity of the car
Solving the equation for F,
Answer:

Answer: So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. ... That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!
Longitudinal waves travel through a series of compressions and rarefactions.
