Explain Why must a cooling system do work to transfer thermal energy?

Although internal energy will not spontaneously flow from a cold region to a hot region, it can be forced to do so by doing work on the system.Refrigerators and heat pumps are examples of heat engines which cause energy to be transferred from a cold area to a hot area. Usually this is done with the aid of a phase change, i.e., a refrigerant liquid is forced to evaporate and extract energy from the cold area. Then it is compressed and forced to condense in the hot area, dumping its heat of vaporization into the hot area. ARE YOU FROM K12?

A car starts from xi = 12m at ti = 0 and moves with the velocity graph shown in figure below. What is the objects position and t=3s and t=4s? Picture in comments below

Our starting velocity is V0 = 12m/s

There are 2 ways of solving this question
First is to use formula which connects starting speed, acceleration (which we would calculate from graph where we can see how speed changes) and time to calculate traveled distance.

S = V0 * t + 1/2*a*t^2

acceleration a is a = -4m/s^2

S(t=3s) = 18

On this value we add 12 initial meters of distance and we get S(t=3s) = 30 meters

For t=4s we get

S = 16 m

Plus initial distance of 12 m we get 30 meters

Answers are 30 and 28 meters.

------------------------------------------
second way is to find surface of graph bellow speed line for 3 and 4 seconds...

Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy

When we say potential energy, this is the energy at rest. And kinetic energy is the energy at motion. So, here are the examples of energy that is transforming from potential energy to kinetic energy: changing thermal energy to electrical energy, and changing radiant energy to electrical energy. Hope this answer helps.

If a substance containing charged ions and electrons can be compressed so that the particles have less space between them, the substance is a gas. plasma. solid. liquid.

Answer: Option (b) is the correct answer.

Explanation:

Plasma is a hot ionized gas that contains approximately equal number of both positive ions and negatively charged electrons.

Thus, we can conclude that if a substance containing charged ions and electrons can be compressed so that the particles have less space between them, the substance is a plasma.

If two carts collide, what type of collision will conserve both momentum and kinetic energy? a. head on b. perfectly inelastic c. none d. perfectly elastic

The appropriate answer is d. perfectly elastic. When a perfectly elastic collision occurs both momentum and kinetic energy are preserved. Momentum is the mass of an object times its velocity while kinetic energy is the energy that a moving object has due to its motion. In an elastic collision kinetic energy would be converted to some other form of energy.

When would the temperature and thermal energy of an object differ?

The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecule and thermal energy is the total kinetic energy of all particles in a given substance.

Which makes fast-moving water a greater force of erosion? A. greater heat capacity B. greater energy C. increased density D. greater oxidation

Answer:

B. Greater energy

Explanation:

Fast moving water is very energetic as its can displace very large rocks, boulders and make pebbles and sand out of them through the process r erosion. Fast moving water have kinetic energy, it opposes anything that come in its way. As river make its own channel by eroding plane. Many antecedent rivers have make their channel by cutting large mountains too.

A football is kicked into the air from an initial height of 4 feet. The height, in feet, of the football above the ground is given by s (t)=-16^2+50t+4, where t is time, in seconds, and t>=0. At what time will the football be 25 feet above the ground? 3.625 seconds 3.20 seconds 0.5 seconds or 3.625 seconds 0.5 seconds or 2.625 seconds

Answer: 0.5 seconds or 2.625 seconds

Explanation:

At t = 0, The ball is 4 ft above the ground.

The height of the football varies with time in the following way:

s(t) = -16 t² + 50 t + 4

we need to find the time in which the height would of the football would be 25 ft:

⇒25 = -16 t² + 50 t + 4

we need to solve the quadratic equation:

⇒ 16 t² - 50 t + 21 = 0

t = \frac{50 \pm \sqrt{50^2-4\times 16\times 21}}{2\times16}

⇒ t = 0.5 s or 2.625 s

Therefore, at t = 0.5 s or 2.625 s, the football would be 25 ft above the ground.

1. In the circuit shown below, with each bulb holding a resistance of 100 ohms, how many amps of current are flowing? Express your number as a decimal. (See Figure) 2. Protons have positive charge, neutrons have negative charge, and electrons have no charge. A. True B. False 3. A complete electric circuit includes a voltage source, current, wires, and something to _________ the flow of current.

These are 3 questions and 3 answers.

Question 1.

Answer: I = 0.01 A

Explanation:

a) Data:

i) Type of circuit: series

ii) R₁ = 100 Ω

ii) R₂ = 100 Ω

iii) V = 2 V

iv) I = ?

b) Formulas

i) Equivalent resistance, R = R₁ + R₂

ii) Ohm's law, V = IR

c) Solution

i) R = 100Ω + 100Ω = 200Ω

ii) I = V / R = 2 V / 200Ω = 0.01 A

Question 2)

Answer: False.

Explanation:

The nuclear model of the atom states that the atom is neutral, and consists of a nucleus, which holds the protons and the neutrons, and the electrons which are around the nucleous (in regions called orbintals).

The electrons are negatively charged and the protons are positively charged.

The magnitudes of the charges of both electrons and protons are equal.

Therefore, for the atom be neutral, the neutrons cannot have charge.

Question 3.

Answer: oppose (or resist).

Explanation:

1) The most basic electrical circuit consists of a 1) potential difference (voltage) source, which gives the "impulse" to the charge to flow, 2) the wire, which is the medium through which the charge flows), and 3) a resistor.

The resistor is the element with "resistance" to the flow of charge, this is it resists or oppose the flow of charge.

Some components, like motors, filaments, buzzers, which content or are resistors per se, transform the current (flow of charge) in other useful forms of energy (motion, light, heat, sound).

The resistor meets Ohm's law which states R = V / I, at constant temperature.
