what happens to heat energy after an object is cooled down lolololol asking for my bff

Answers

Answer:

Heat energy does not cool. Objects cool. Energy is not an object. Now, what happens when an object cools is that it gives off some of its thermal energy by one or more mechanisms: radiation, conduction, or convection. In radiation the energy escaped the object as electromagnetic waves - you see the red hot poker slowly dim as it cools, in conduction the energy is transferred Mechanically by the atoms of the hot object being in physical contact with those of the cool object and in convection the hot material moves to a cooler region where it gives up its heat energy by either radiation or conduction.

Answers

Answer: A

Explanation:Convection currents in the mantle Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle.

300mph = 48.1 m/t

xt

300t = 48.1

÷300

t = 48.1/300

t = 0.16033333333 hr

A post driver has a mass of 10kg. Calculate the change in GPE stored when the post driver is lifted by 50cm above the post. The gravitational field strength on earth is 10N/kg.

Answers

Answer:

500kJ

Explanation:

Common equation;

GPE = mgh

m = mass - in kg

g = gravitational field strength - in N/kg

h = height lifted/lowered - in meters

GPE = 10kg × 10N/kg × 5000m

GPE = 500000Nm

GPE = 500000J

GPE = 500kJ

What does Einstein's famous equation for nuclear energy, E=mc2, mean?


Mass and energy are produced in a nuclear reaction.

Mass and energy are destroyed in a nuclear reaction.

Some mass and energy are lost in a nuclear reaction.

Some mass is converted into energy in a nuclear reaction.

Answers

Answer:

1.It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

2.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

3.In nuclear reactions, mass is never conserved—some mass is exchanged for energy and energy for mass. Nuclear reactions take place in an atom's nucleus. In a spontaneous nuclear reaction, such as radioactive decay, mass is "lost" and appears as energy in the form of particles or gamma rays.

4.In a nuclear reaction, mass decreases and energy increases. The sum of mass and energy is always conserved in a nuclear reaction.

5.The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei.

Which statement accurately describes something that Yolanda can do as a part of her study? She can use destructive interference to generate a wave with an amplitude of 3. 1 m. She can use constructive interference to generate a wave with an amplitude of 1. 5 m. She can use destructive interference to generate a wave with an amplitude of 0 m. She can use constructive interference to generate a wave with an amplitude of 3. 5 m.

Answers

Option D is correct. She can use constructive interference to generate a wave with an amplitude of 3.5 m.

What is a wave?

A wave is a phenomenon that flows across a material medium without leaving any lasting mark. Mechanical or electromagnetic waves can be used to classify them.

The wavelength of waves obtained by the interference is more than the two primary waves.

Hence Option D is correct. She can use constructive interference to generate a wave with an amplitude of 3.5 m.

Hilda looks at a cd and sees different colors. Which best explains why she sees different colors when light strikes a cd?.

Answers

Answer:

The smooth surface of the CD causes wavelengths of light to scatter. The CD at this point acts somewhat like a prism splitting white light into the colors of the rainbow. This is called the visible spectrum of light and is composed of the colors red, orange, yellow, green, blue, indigo and violet.

Explanation:

Answer: The reflected wave has less energy

Explanation:

The incident wave would be the light wave before it comes in contact with the CD. Once the incident wave hits the CD, there is a reflected wave which will have some portion of energy from the incident wave. The reflected wave is a different color from the incident wave due to the reflected wave having less energy. Less energy means a different wavelength of visible light

Two technicians are discussing a resistance measurement between the can-h and can-l wires. Technician a says this measurement should be done with the ignition switch in the "run" position. Technician b states that a measurement of 0 ohms indicates an open in the network. Which technician is correct?

Answers

Based on the information given, the technician that's correct regarding the resistance measurement between the wires is Technician A.

Who is a technician?

It should be noted that a technician simply means an individual that's in charge of looking after the technical equipment in an organization.

In this case, Technician A is correct. Technician B is incorrect as zero-ohm doesn't indicate an open circuit in the network but rather, a complete circuit.

Explanation:

975kg can be recovered so 975x10,000,000

The total mass of magnetic metals that could be recovered from scrapped cars each year will be equal to 9750,000,000.

What is an arithmetic operation?

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the provided given data in the question,

Ten million cars are scrapped each year, then the total mass of magnetic material that could be recovered,

975kg can be recovered so,

= 975 × 10,000,000
