Answer:
The student which is correct is Anya
Explanation:
The wavelength of a wave is the length of one complete wave cycle and it is represented by Greek letter lambda (λ)
The frequency of a wave is the number of waves (complete wave cycles) passing a given point over a given time period and the frequency is represented by the Greek letter nu (ν) and also as "f" (which is the first letter of the word "frequency")
Therefore, the speed, "v", (different from nu (ν)) of the wave is given as follows;
v = f × λ
From which we have;
λ = v/f
∴ λ ∝ 1/f
Which indicates an inversely proportional relationship between the wavelength and the frequenct
From which we have that as the wavelength decreases, the frequency increases
Therefore, Anya decrease increase is correct

Given:
m = 36,287 kg, the mass of the truck
P = 907,175 (kg-m)/s, the truck's momentum.
Let v = the truck's velocity.
By definition, the momentum is
P = m*v
Therefore
v = P/m
= (907175 (kg-m)/s) / (36287 kg)
= 25 m/s
Answer: 25 m/s
Answer:
Assume that the planet <em>has a defined angular momentum (this is not true due to tidal friction). So if mass is farther away from the center of mass it will have more angular momentum, and if mass is near you will have more angular momentum.</em>
If the mass is similar to the center of mass and slower if the mass is farther from the center of mass, an object will spin faster to combat this. Building skyscraper will also slow down the earth and dropping leaves will raise the angular velocity.
A great example of this is with figure skaters, when they want to spin faster they tuck themselves in tightly, bringing more mass close to the center of mass which increases angular velocity there.
