<u>Answer:</u> The correct answer is Option b.

<u>Explanation:</u>

Direct relationship is defined as the relationship in which if one variable increases, the other also increases and vice-versa.

x\propto y

where, 'x' and 'y' are two variables.

Indirect relationship is defined as the relationship in which if one variable increases, the other variable decreases and vice-versa.

x\propto \frac{1}{y}

where, 'x' and 'y' are two variables.

In the question, the two variables are Temperature and Volume and to determine the proportionality of the two variables, we will look at the slope of the graph.

If the slope of the graph is positive, then these variables follow direct proportionality and if the slope is negative, then these variables follow inverse proportionality.

Slope of the graph is calculated by using the formula:

\text{Slope}=\frac{y_2-y_1}{x_2-x_1}

\text{Slope}=\frac{800-600}{80-60}=\frac{200}{20}=10

As, the slope is positive, so the volume and temperature follow direct proportionality.

Hence, the correct answer is Option b.

A planet has two moons with identical mass. Moon 1 is in a circular orbit of radius r. Moon 2 is in a circular orbit of radius 2
saw5 [17]

Answer:

Half as large.

Explanation:

Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:

F_1=\frac{GMm}{r}

F_2=\frac{GMm}{2r}

Which clearly shows that the force that the planet exerts on the Moon 2 is half  the force it exerts on the Moon 1.
