  • Human beings use water for drinking bathing, cooking, washing, watering etc.
  • Industries and factories use water for manufacturing purposes.
  • Animals use water for drinking and bathing.
  • Plants and trees use water to grow and produce food.
  • Farmers use water to cultivate the land and fulfil the population hunger.
  • Power plants and nuclear plants use water to produce energy and power.
  • More than 70% of our body is made up of water. Without it, the human race will not survive.
  • Water in our body helps in regulating body temperature.
  • It keeps our organs and tissue moist and functioning.
  • It helps in digestion and breaking down of the food we take inside our bodies.
  • It keeps our skin healthy and nutritious.
  • Water is so precious and very important for us.

What is the magnitude of the kinetic frictional force
Sophie [7]

Answer:

Magnitude of kinetic force is the product of the normal force and the coefficient of kinetic friction.

Explanation:

The kinetic frictional force is the force which is experienced in the moving surfaces of bodies.The magnitude of the force is affected by the coefficient of kinetic friction between the material of two bodies in contact. Mathematically, it is expressed as;

Fk=μk*η

where;

  • Fk=force of kinetic friction
  • μk=coefficient of kinetic friction
  • η=normal force

If a person is near sighted what type of lens will their glass have to correct their eyesight
oksian1 [2.3K]

Answer:

Since the nearsighted eye over converges light rays, the correction for nearsightedness is to place a diverging spectacle lens in front of the eye. This reduces the power of an eye that is too powerful.

A falling ball of mass 0.5 kg experiences a downward force due to gravity of mg (where g = 9.8 m/s2) and an upward force of air
schepotkina [342]

Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8 m/s^2

<u>Given the following data:</u>

  • Mass = 0.5 kg
  • Acceleration due to gravity = 9.8 m/s^2
  • Upward force = 3.5 N.

To find ball's acceleration, we would apply Newton's Second Law of Motion:

First of all, we would determine the net force acting on the ball.

Net \; force = Upward\;force + Downward\;force

Downward\;force = 0.5 × 9.8

Downward force =  4.9 N

Net \; force = 3.5 + 4.9

Net force = 8.4 N

Mathematically, Newton's Second Law of Motion is given by this formula;

Acceleration = \frac{Net\;force}{Mass}\\\\Acceleration = \frac{8.4}{0.5}

<em>Acceleration = 16.8 </em>m/s^2<em />

Therefore, the acceleration of the ball is 16.8 m/s^2

Need help with physics electric question!❤️
LUCKY_DIMON [66]

The output voltage is 10 times the input voltage.

So the output coil has 10 times as many turns as the input coil has.

That's how transformers work.

Complicated, huh !

10 times 1,000 turns = <em>10,000 turns</em>
