The force of air particles over an area is?

Answers

Answer;

Air pressure

Explanation;

  • Pressure is the force that is applied over a unit of area. Air pressure is the weight of air molecules pressing down on the Earth. It is the force exerted by air particles on the earth's surface.
  • The column of air extends to the top of the atmosphere.  As one move up increasing the altitude, the air pressure decreases since the air column is reduced.
That's the "air pressure" everywhere on that area.

Suppose you ride your bicycle to the library traveling at 0.5 km/min. It takes you 25 minutes to get to the library. How far did you travel?

Answers


If you cover 0.5 km every minute, and keep it up for 25 minutes,
then you will cover

0.5  +  0.5  +  0.5  +  0.5  +  0.5  +
0.5  +  0.5  +  0.5  +  0.5  +  0.5  +
0.5  +  0.5  +  0.5  +  0.5  +  0.5  +
0.5  +  0.5  +  0.5  +  0.5  +  0.5  +
0.5  +  0.5  +  0.5  +  0.5  +  0.5     =   12.5 km.

An easier way to write the same thing is

             (25) times (0.5 km)  =  12.5 km.

An electron is pushed into an electric field from infinity where it acquires a 1-V electrical potential. Suppose instead that two electrons are pushed from infinity the same distance into the same electric field. The electrical potential of the two electrons is ___________.a) 0.5V
b) 1V
c) 0.25V
d) 4V
e) 2V

Answers

Answer:

The electrical potential of the two electrons is 1 V.

(b) is correct option.

Explanation:

Given that.

Electric potential = 1 V

We know that,

The electric potential depends on the distance.

The electric potential does not depend on the charge.

The formula of electric potential

V=Ed

Where, E = electric field

d = distance

Hence, The electrical potential of the two electrons is 1 V.

a horse moves a sleigh 1.00 kilometers by applying a horizontal 2000 Newton force on its harness for 45 minutes. what is the power of the horse?

Answers

--  If 2,000 newtons of force were applied through a distance of 1,000 meters,
then 2,000,000 newton-meters = 2,000,000 joules of work were done.

-- 45 minutes = (45 x 60) = 2,700 seconds

-- Power = (work) / (time) = (2,000,000 j) / (2,700 s) = 740.74 watts

Interestingly, that's almost exactly 1 horsepower.  (0.99295... of 746 watts)
