3.20-m-long, 500 kgkg steel uniform beam extends horizontally from the point where it has been bolted to the framework of a new

suter [353]

Answer:

10,035

Explanation:

Length of the beam is 3.2m

Mass of steel beam is 500kg

Weight of steel =mg

Ws=400×9.8=4900N

Also, man of mass =70kg

Weight of man(Wm)=70×9.8=686N

The weight of the man will act as the middle of the beam

Torque is given as Force ×distance

tnet=Wm×L + Ws×L/w

tnet=686×3.2+4900×1.6

tnet=10,035.2Nm

The net torque about where the beam is bolted is 10,035.2Nm

Have researchers have now been able to cool substances to absolute zero

ikadub [295]

It's a law of nature, which I don't understand too well, that we can
cool things as close to Absolute Zero as we want to, but we can
never get all the way there.

I think that individual atoms and molecules have been cooled in
the laboratory to within a few thousandths of a Celsius degree
of it ... actually not too shabby an accomplishment !

WOW ! I just went and searched online for more information
on this subject. (You can't imagine what great stuff you can find
by doing that. You ought to try it some time.)

The 1997 Nobel Prize in Physics was awarded to a team of three
physicists who invented a method of using lasers to slow down the
motion of atoms, and that's the same thing as cooling them. They
were able to cool some atoms to a temperature of 240 millionths
of a degree above Absolute Zero !

he measured flow rate of water through a 20 mm diameter pipe is 75 L/min. What is the average velocity (in m/s) of water flowing

Masteriza [31]

Answer:

Average velocity of water flow through the pipe = 3.98 m/s

Explanation:

Diameter of pipe = 20 mm

Discharge = 75 L/min

We know that

Discharge = Area x Velocity

$\texttt{Area of pipe}=\frac{\pi d^2}{4}=\frac{\pi \times (20\times 10^{-3})^2}{4}=3.14\times 10^{-4}m^2$

Discharge = 75 L/min

$=\frac{75\times 10^{-3}}{60}=1.25\times 10^{-3}m^3/s$

Substituting

$1.25\times 10^{-3}=3.14\times 10^{-4}\times V\\\\V=3.98m/s$

Average velocity of water flow through the pipe = 3.98 m/s

Akimi4 [234]

As No diagram attached I am taking all are connected in series

We know

$\boxed{\sf C_{eq}=C_1+C_2\dots}$

$\\ \sf \longmapsto C_{eq}=12+12+7+15+15+15$

$\\ \sf \longmapsto C_{eq}=24+7+45$

$\\ \sf \longmapsto C_{eq}=76\mu F$
