Answer:

1.33 m

Explanation:

Tom weighs 600 N and is 2 meters from the pivot. So his moment is:

τ = Fr

τ = (600 N) (2 m)

τ = 1200 Nm

To balance the see-saw, Jeremy must create an equal and opposite moment.

τ = Fr

1200 Nm = (900 N) r

r = 1.33 m

So Jeremy must sit 1.33 m from the pivot on the other side.

Answer:

(B) the increase in the car's potential energy is 3,660,000 J

Explanation:

Given;

mass of the car, m = 1,000 kg

height through the car was drove, h = 366 m

acceleration due to gravity, g = 10 m/s²

The increase in the car's potential energy is calculated as;

P.E = mgh

P.E = 1000 x 10 x 366

P.E = 3,660,000 J

Therefore, the increase in the car's potential energy is 3,660,000 J

Which image illustrates why dark clothing helps to keep you warm on a cool, sunny day?

xeze [42]

Answer:

Explanation:

I suppose it has to do with the way the diagram is drawn. The heat does not reflect which makes both A and B incorrect.

C would have nothing to do with either reflection or refraction.

That only leaves D which is the answer.

Calculate the vapor pressure for a mist of spherical water droplets of radius 3.70×10−8m surrounded by water vapor at 298 K. The

poizon [28]

Answer:

The vapor pressure for a mist is $P= 25.92\ Torr$

Explanation:

From the question we are given that

The radius is $r = 3.70 *10^{-8} m$

The temperature is $T = 298K$

The vapor pressure of water $P_o = 25.2\ Torr$

The density of water is $\rho = 998 kg.m^{-3}$

The surface tension of water is $\sigma = 71.99 m N \cdot m^{-1}$

Generally the equation of that is mathematically represented as

$ln (\frac{P}{P_0} ) = \frac{2 \sigma M}{r \rho RT}$

Where P is the vapor pressure for mist

R is the ideal gas constant = 8.31

making P the subject in the formula

$P = e^ {\frac{2 \sigma M}{r \rho RT}} * P_0$

$= e^{\frac{2 *(0.07199)(0.018)}{(3.70*10^{-8})(998)(8.31)(298)} } * 25.2$

$P= 25.92Torr$
