The book is in motion and at the moment there is no one pushing it to the right. (Remember: a force is not needed to keep a moving object moving to the right.) The forces acting upon the book are shown below.

If you increase the amount of spinach you eat, then you will increase the iron in your blood. What's the dependent variable?
Solnce55 [7]
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.

Common transparent tape becomes charged when pulled from a dispenser. If one piece is placed above another, the repulsive force
liraira [26]

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.

Use the table to answer the question.
e-lub [12.9K]

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
