Work done by force is given by formula

now here work done against friction is given so force of friction here is

It moved by three corridors with each measures

so total distance will be

now from above formula of work done we will say


so above is the work done to move three corridors
Answer:
The number of revolutions turned by the centrifuge is 8250 revolutions.
Explanation:
Given;
number of revolution per minutes, ω = 15000 rpm
time of motion, t = 330 s = 5.5 minutes
The number of revolutions turned by the centrifuge is given by;

Therefore, the number of revolutions turned by the centrifuge is 8250 revolutions.
Answer to your question is B. I did a science lab over this...
Test was to see which would dissolve fastest... A tablet in warm water... and a tablet in cold water....
And this question isn't asking for solids or gasses.... because something dissolves with a liquid :P thanks...
Answer:
The velocity (
) of the wave is 3.08
.
Explanation:
According to the figure, the distance (
) between a trough and its adjacent crest is
. Also the wavelength (
) of the wave is
. Pepe and Alfredo count 11 crests to pass the raft in
= 21.5 s.
So, the time period (
) of oscillation of the wave is

So, the velocity (
) of the wave is

Answer:
magnetic force due to gravity
Explanation:
nowno that is because that's what the geography teacher taught us back in don't remember but it's true
