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
Answer:
In a chemical reaction, an iron atom became the ion which means that iron atom by loosing two electrons from its valence shell has oxidized into positively charged ion
Explanation:
Answer: 6.4 times.
Explanation:
First, remember the definition of work as:
W = F*d
where W is work, F is force and d is distance.
The work applied when using the machine is:
W = 10N*14m = 140J
The work that you would apply if you did not use the machine is:
W' = 180N*5m = 900J.
The ratio W'/W is = 900J/140J = 6.4
This means that the machine has made 6.4 times the work easier. (you needed 6.4 times less work to do the task
