Answer:

There are many common household objects that feature electric motors, such as vacuum cleaners, blenders, the sink garbage disposal, and the hair dryer. There are also small electric motors in common toys, such as in the tiny cars that make them go. Some office supplies have them too: pencil sharpeners, coffee-bean grinders, ceiling fans, the printer, and even the vibrator in a cell phone!

A proton in a particle accelerator is traveling at a speed of 0.99c
Gwar [14]

A proton in a particle accelerator is traveling at a speed of 0.99c has a speed magnitude of 2.97 x 10⁸ m/s.

<h3>What is speed of proton?</h3>

The speed of a proton is the rate at which a proton is moving through a given space.

The given speed of the proton is 0.99c

where;

  • c is speed of light

<h3>What is speed of light?</h3>

The speed of light in vacuum, commonly denoted c, is a universal physical constant that is important in many areas of physics.

The value of speed of light in a vacuum is given as 3 x 10⁸ m/s.

The speed of the proton is calculated as follows;

v = 0.99 x 3 x 10⁸ m/s.

v = 2.97 x 10⁸ m/s.

Thus, a proton in a particle accelerator is traveling at a speed of 0.99c has a speed magnitude of 2.97 x 10⁸ m/s.

At $.110 per kWh, what does it cost to leave a 40-W porch light on day and night for a year?
nlexa [21]

The cost of electricity be  $ 38.544.

<h3>What is electricity?</h3>

Electricity is the passage of charges in a conductor. From one end of the terminal to the other, charges are transmitted. Usually, the terminal moves from positive to negative. Since the nucleus holds the electrons loosely, they can move freely throughout the body.

Watts are units of power used to measure electrical output. 

Price of electricity is $ 0.110 per kWh .

If a 40-W porch light on day and night for a year, total amount of electricity spend = power of the bulb × time

= 40 W × 1 year

= 40 W × 365 day

= 40 W × 365 ×24 h

= 350400 Wh

= 350.4 kWh.

Hence,  the cost of electricity be = $350.4 × 0.110 =  $ 38.544.

A 600 kg car is at rest, and then accelerates to 5 m/s.
Crank

Answer:

0

7500J

7500J

Explanation:

Given parameters:

Mass of car  = 600kg

Velocity  = 5m/s

Unknown:

Original kinetic energy  = ?

Final kinetic energy  = ?

Work used  = ?

Solution:

The kinetic energy of a body is the energy due to the motion of a body.

It can be solve mathematically using expression below;

                K.E  = \frac{1}{2}  m v²

  where m is mass

              v is velocity

original kinetic energy;

  The car started at rest and v = 0, therefore K.E  = 0

Final kinetic energy;

           K.E  = \frac{1}{2}  x 600 x 5²   = 7500J

Work done:

   Work done  = Final K.E  - Initial K.E  = 7500 - 0 = 7500J
