Question

Name and define the type of energy possessed by the following.​

Answer 1

Answer:

a) heat energy

b) sound energy

c) magnetic energy.

Explanation:

a) Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat. For example, an ice cube has heat energy and so does a glass of lemonade.

A form of energy, heat has the unit joule (J) in the International System of Units (SI).

Involves the use of heat, with or without the presence of oxygen, to convert biomass materials into other forms of energy.

Example

• change in temperature = (100 - 25) = 75.0°C.
• change in thermal energy = mass × specific heat capacity × change in temperature.
• = 0.200 × 4,180 × 75.0.
• = 62,700 J (62.7kJ)

Thermal effects refer to the substantial loss of thermal energy from spent waters to the environment primarily due to the low efficiency of geothermal power plants. Excess heat emitted in the form of steam may affect cloud formation and change the weather locally.

b) Sound energy is a form of energy that can be heard by living beings. Only those waves that have a frequency of 16 Hz to 20 kHz are audible to humans. However, this range is an average and will slightly change from individual to individual.

Everyday Examples of Sound Energy

• An air conditioning fan.
• An airplane taking off.
• A ballerina dancing in toe shoes.
• A balloon popping.
• The bell dinging on a microwave.
• A boom box blaring.
• A broom swishing.
• A buzzing bee.

Sound energy may be converted into electrical energy for transmission, and later the electrical energy can be converted back into sound energy at the receiving end. An example of such transformations could be seen in the microphone and the loudspeaker. Sound, like heat energy is easily lost.

Sound energy travels in waves and is measured in frequency and amplitude. Amplitude measures how forceful the wave is. It is measured on a Logarithmic scale and reported[1] in decibels or dBA of sound pressure. Frequency is measured in the number of sound vibrations in one second.

Sources of Sound Energy

Acoustic Instruments.

• Electronic Instruments. Electrical vibrations are the starting point of sounds from electronic organs and synthesizers. ...
• Living Things. Animals and people make sounds with their vocal cords, their mouths and other body parts. ...
• Machines. ...
• Nature.

c) Each magnetic field contains energy, also called magnetic energy. She is a constant in physics. Because a magnetic field is generated by electric currents, the magnetic energy is an energy form of moving charge carriers (electrons).

• Metal machine shop holding devices : ...
• Scrap yard and steel mill lifting : ...
• Separation of materials : ...
• Radiation isotope creation : ...
• Pure Physics research : ...
• Motors – automotive, lawn mower, kitchen mixer

For example, if an iron nail was placed near a bar magnet, the nail would experience a magnetic force. ... Like ends of a magnet repel each other and unlike poles attract each other.

hopefully its helped u dear :)
