The dependent variable is the iron in your blood because it depends on the amount of spinach you eat. The independent variable will be the amount of spinach you eat since it doesn’t depend on the iron for anything.
Answer:
Explanation:
Let the equal charges be Q .
Force between charges = k Q² / R where R is distance between charges , k = 9 x 10⁹.
Putting the charges
Force F = 9 x 10⁹ x Q² /( .72 x 10⁻²)²
= 17.36 x 10¹³ Q² N
This force equals weight so
17.36 x 10¹³ Q² = 15.7 x 10⁻³
Q² = .90 x 10⁻¹⁶
Q = .95 x 10⁻⁸
= 9.5 x 10⁻⁹
= 9.5 nC.
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
