Answer:

When an object in motion with no specific path and changes its motion suddenly is called random motion.

eg:Moving Clouds. Bees heading towards a flower in any direction. A rolling football during a game.

An electric motor has an effective resistance of 29. 4 ω and an inductive reactance of 42. 6 ω. When working under load. the rms voltage across the alternating source is 442 v.  The rms current will be  8.54 A

AC stands for “Alternating Current,” meaning voltage or current that changes polarity or direction, respectively, over time. AC electromechanical generators, known as alternators, are of simpler construction than DC electromechanical generators.

RMS or root mean square current/voltage of the alternating current/voltage represents the D.C current/voltage that dissipates the same amount of power as the average power dissipated by the alternating current/voltage. For sinusoidal oscillations, the RMS value equals peak value divided by the square root of 2.

I (RMS) = RMS voltage / \sqrt{R^{2}+ X_{L} { ^{2}  }

           =  442 / \sqrt{29.4^{2} + 42.6^{2}  }

           = 442 / \sqrt{864.36 + 1814.76}

           = 442 / \sqrt{2679.12}

           = 8.54 A

A horse has a momentum of 25 kg*m/s and a velocity of 2.5 m/s. What is the horse mass?
Ne4ueva [31]
<h3>Answer:  10 kg</h3>

==================================================

Work Shown:

We have these variables

  • p = momentum = 25 kg*m/s
  • m = mass = unknown
  • v = velocity = 2.5 meters per second

Solving for the mass gets us...

p = m*v

25 = m*2.5

25/2.5 = m

10 = m

m = 10

The mass of the horse is 10 kg.

3 things that Gravity affects
slamgirl [31]

Answer: See explanation

Explanation:

Gravity is simply referred to as the force of attraction between two particles or masses. Through gravity, the moon moves round the Earth.

Gravity also causes a fruit to fall from its tree. It can also cause an object to roll and fall from the table to the ground. In gravity, distance and mass are vital.

Before Newton and develop reflecting telescopes what instruments did astronomers use?
never [62]

The first telescopes were refracting telescopes ... a tube
with lenses at both ends.  The quality of the image depends
on the quality of both lenses, because the light must pass
through both of them. 

The reflecting telescope was an improvement, because the
light doesn't have to go through the mirror.  The quality of the
primary mirror only depends on the shape and shinyness of
its surface. 

If you could carve an optically perfect parabolic surface out of
a piece of wood and coat it with a thin layer of shiny silver, then
you could use a log to make a good reflecting telescope.
II seem to recall that Newton made one out of brass !
