Answer:

(C) The volume of an atom is mostly empty space.

Explanation:

Rutherford's nuclear theory:

  Rutherford's performed an experiment with the help of alpha particle and gold foil film.By doing this experiment he concluded that

1.Mass and charge of an atoms is located in the nucleus.

2.Nucleus are surrounding by electron .Nucleus is a positive charge particle and electron is a negative charge particle.

According to Rutherford's nuclear theory,the volume of an atom is mostly empty space.

So option C is correct.

(C) The volume of an atom is mostly empty space.

A 10 hp motor is used to raise a 1000 Newton weight at a vertical distance of 5 meters. What is the work the motor performs?
Aleksandr [31]

The work done by a 10 HP motor when it raises a 1000 Newton weight at a vertical distance of 5 meters is <u>5kJ</u>.

Define work. Explain the rate of doing work.

Work is <u>the energy that is moved to or from an item by applying force along a displacement</u> in physics. For a constant force acting in the same direction as the motion, work is <u>easiest expressed as the product of </u><u>force </u><u>magnitude and distance traveled</u>.

Since the <u>force </u><u>transfers one unit of energy for every unit of </u><u>work </u><u>it performs</u>, the rate at which work is done and energy is used are equal.

Solution Explained:

Given,

Weight = 1000N and distance = 5m

A/Q, the work here is done in lifting then

Work = (weight) × (distance moved)

         = 1000 X 5

         = 5000Nm or 5000J = 5kJ

Therefore, the work done in lifting a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.

A set of civil construction plans shows a distance of 131 meters across the front of a piece of property. You need to convert th
Hoochie [10]

Answer:

429.5 ft

Explanation:

We are told that;

1 ft = 0.305 meters

We want to convert 131 meters to ft, by proportion we have;

Distance = (131 × 1)/0.305

Distance = 429.5082 ft

We want to approximate to the nearest tenth of a foot.

This gives us;

Distance = 429.5 ft
