T = F x d, 800N x 2m = 3m x F(Sally) = 1600
1600 / 3m = 533 1/3 N

If the temperature of a gas is increased by 10x, what will happen to the volume?
xxMikexx [17]

The volume of a gas will increase by ten times if the temperature is increased by ten times.

<h3>Relationship between the volume of a gas and temperature</h3>

The relationship between the volume of a gas and its temperature is explained in Charles' law of gases which states that:

  • The volume of a fixed mass of gas is directly proportional to its temperature provided the pressure of the gas is kept constant.

This means that if the temperature of a gas is increased by any given factor, the volume increases by the same factor proportionally.

Therefore, if the volume of a gas will increase by ten times if the temperature is increased by ten times.

Gemiola [76]

Answer:

E = 2 \times 10^{-3} V

Explanation:

As we know that rate of change in flux will induce EMF

So here we can

EMF = \frac{d\phi}{dt}

now we have

EMF = \pi r^2\frac{dB}{dt}

now we also know that induced EMF is given by

\int E. dL = \pi r^2\frac{dB}[dt}

E (2\pi r) = \pi r^2\frac{dB}{dt}

E = \frac{r}{2}(\frac{dB}{dt})

now plug in all values in it

E = \frac{0.0133}{2}(0.12 t)

E = 8 \times 10^{-4} (2.50) = 2 \times 10^{-3} V/m
