Kate is working on a project in her tech education class. She plans to assemble a fan Motor. Which form of energy does the motor convert most of its electric energy into

Answers

Answer 1

Answer:

Answer: Motor convert most of its electric energy into mechanical energy.

Explanation:

An electric motor is an electric machine which converts electric energy into mechanical energy.

Electrical energy → Mechanical energy.

The principle on which it works is that when current carrying conductor is placed under the influence of magnetic field it experiences force which termed as mechanical force.

Answer 2

Answer: kinetic energy. the electricity makes the fan move. it uses potential energy and converts it into kinetic energy from the electricity.

Which of the following types of energy originates below Earth's surface?A. electrical energy
B. geothermal energy
C. mechanical energy
D. electromagnetic energy

Answers

Geothermal energy. Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made. I hope this answer and these explanations helped!

How and why can two lethal elements combine to form an essential
compound for health?

Answers

Answer:

Two lethal elements can combine to form an essential compound for health by undergoing a chemical reaction such that the properties of the individual elements are different from the properties of the product and are no more lethal

Example Mercury and Sulfur combine to form cinnabar which is used as a medicine to relieve pain, antiseptic, and to cure diseases

Mercury and sulfur combines because mercury readily combines with sulfur at high temperatures

Explanation:

Mercury is a lethal element that also has harmful effects on the neurological system

Sulfur is lethal when too much of it is consumed

During a race, a sprinter increases from 5.0 m/s to 7.5 m/s over a period of 1.25s. What is the sprinter’s average acceleration during this period?

Answers

Answer:

$\boxed {\boxed {\sf 2 \ m/s^2}}$

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

$a=(\Delta v)/(t)$

The time is 1.25 seconds. The change in velocity is the difference between the initial velocity and the final velocity.

$\Delta v=v_f-v_i$
The final velocity is 7.5 m/s and the initial velocity is 5.0 m/s
$\Delta v =7.5 \ m/s-5.0 \ m/s=2.5 \ m/s$

$\Delta v= 2.5 \ m/s\nt=1.25 \ s$

Substitute the values into the formula.

$a=(2.5 \ m/s)/(1.25 \ s)$

Divide.

$a=2 \ m/s^2$

The sprinter's average acceleration is 2 meters per second squared.

Answer: 2 m/s^2

Explanation: Hope this helps :)

Gas pressure in a closed system is caused by _____.

Answers

Answer:

rapid diffusion of gas throughout the system

Explanation:

It is caused by she system letting off fumes and making gas pressure.

a car traveling at 40m/s starts to decelerate steadily. it comes to a complete stop in 12 seconds. what is the acceleration?

Answers

Velocity - v =0 m/s,

initial velocity - v(0)= 40 m/s

a - acceleration,

time - t = 12 s.

v=v(0) - at

0 = 40m/s - a*12s

12a = 40

a = 3.3 m/s²

When energy is transferred to air, what happens to the particles of air? (1 point) They move slower. They move faster. They cool down. none of the above

What is kinetic theory of gases?

A huge number of submicroscopic particles, including atoms and molecules, are used in the kinetic theory of gases, a theoretical model, to characterize the molecular makeup of the gas.

The idea also states that gas pressure results from particles slamming into one another and the container walls. In addition to defining physical characteristics like temperature, volume, and pressure, kinetic theory of gases also defines transport characteristics like viscosity, thermal conductivity, and mass diffusivity.

It essentially explains every characteristic connected to the tiny phenomenon. The idea is significant because it aids in creating a relationship between macroscopic properties and tiny phenomena.

this question is a critical question. as we all know, when energy is added to any state of water, the particles move faster. and when energy is taken away from any state of water, the particles reduce speed. same with the particles of air. when energy is added; they move faster. when energy is removed; they move slower. so the answer is they move faster
