- Question
Which of the following is Not a form of Energy?
Options- A. Heat
- B. Sound
- C. Motion
- D. Pressure
- Correct Answer
- Pressure
ExplanationPressure is Not a form of Energy.
Energy : It is defined as the ability to do work.
Energy comes in two basic forms. They are :
1. Potential Energy
2. Kinetic Energy
Potential Energy is any type of stored energy. It can be chemical, nuclear, gravitational, or mechanical.
Kinetic Energy is found in movement. An airplane flying or a meteor plummeting each have kinetic energy. Even the tiniest things have kinetic energy, like atoms vibrating when they are hot or when they transmit sound waves. Electricity is the kinetic energy of flowing electrons between atoms.

Correct Answer: Decreasing pressure
Explanation:
A barometer is a tool that measures air pressure
A rising barometer indicates increasing air pressure, a falling barometer indicates decreasing air pressure.
In space, there is a nearly complete vacuum, so the air pressure is zero.
Correct Answer: Humidity
Explanation:
The amount of water vapor ranges from a trace amount up to 4% of the mass of air. Water vapor exists as an invisible gas in the air.
The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity.
The maximum amount of water vapor that can be in the air depends on the air temperature.
Correct Answer: a wave reflects upon itself
Explanation:
A standing wave also known as a stationary wave, is a wave in which its peaks or any other point on the wave do not move spatially.
This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. The most common cause of standing waves is the phenomenon of resonance, in which standing waves occur inside a resonator due to interference between waves reflected back and forth at the resonator's resonant frequency.
Hence, standing wave occurs when a wave reflects upon itself.
Correct Answer: the brighter bulb has smaller resistance
Correct Answer: K.E of random motion of molecules
Correct Answer: Nuclear Power Plant
Explanation:
Nuclear Power Plant uses a Non Renewable Energy Source.
Non-renewable energy is that source of energy which can not be used again and again. This sort of energy is sustainable to exhaustion.
Non renewable energy is that form of energy which is subject to deletion. This type of energy is of many uses to us. It can be used to produce electricity, heating, cooking, transportation and manufacturing. 85% of the energy used in the industrial processes is form the non-renewable type of energy.
Correct Answer: Voltage
Explanation:
A transformer that increases voltage from primary to secondary (more secondary winding turns than primary winding turns) is called a Step-Up Transformer.
Conversely, a transformer designed to do just the opposite is called a Step-Down Transformer.
Correct Answer: Evaporation
Explanation:
Evaporation is the process that allows water to enter into the atmosphere.
Sunlight turns liquid water into water vapor which then rises higher into the atmosphere and forms into clouds.
Plants, too, help water get into the atmosphere through a process called transpiration.
Correct Answer: 1 TB
Explanation:
1 TB > 1 GB > 1 MB > 1 KB
1 Tb (Tera Byte) = 1024 GB
1 GB (Giga Byte) = 1024 MB
1 MB (Mega Byte) = 1024 KB
1 KB (Kilo Byte) = 1024 Bytes
1 Byte = 8 Bit
Hence, largest unit of information is TB (Tera Byte) and smallest unit of information is Bit.
Correct Answer: All the above
Explanation:
Metamorphism is the change of minerals or geologic texture in pre-existing rocks, without the protolith melting into liquid magma. The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids.
The parent rock must be in solid form. Tons of pressure must be applied for metamorphism to happen. The process must take place underground.
