A car has a momentum of 20,000 kg • m/s. what would the car’s momentum be if its velocity doubles? 10,000 kg • m/s 20,000 kg • m
2 answers:
Answer: 40,000 kg • m/s
Explanation:
the momentum of an object is defined as the product between its mass (m) and its velocity (v):
From the formula, we see that there is a direct proportionality between the momentum, p, and the velocity, v. Therefore, if the velocity is doubled, then the momentum doubles as well.
In this problem, the initial momentum of the car is 20,000 kg • m/s. Therefore, if the velocity of the car is doubled, the momentum of the car will double as well, and it will becomes

The distance between the two positive, two negative, or two minimal points on the waveform is known as the wavelength of the wave. The following formula expresses the relationship between the frequency and wavelength of light:
f = c / λ
where, f = frequency of light
c = speed of light
λ = wavelength of light
Given data = f = 1.72×Hz
Therefore, λ = 3× / 1.72×
λ = 1.74×m

Answer:
Speed of air = 1106.38 ft/s
Explanation:
Speed of sound in air with temperature
Here speed is in m/s and T is in celcius scale.
T = 50°F
Substituting
Now we need to convert m/s in to ft/s.
1 m = 3.28 ft
Substituting
Speed of air = 1106.38 ft/s
