- Question
The combined gas law relates which of the following?
Options- A. Volume & Temperature
- B. Temperature & Pressure
- C. Volume & Pressure
- D. Volume, Temperature & Pressure
- Correct Answer
- Volume, Temperature & Pressure
ExplanationThe combined gas law states that the ratio between the pressure-volume product and the temperature of a system remains constant.
Hence it depends on all the three Volume, Temperature & Pressure.

Correct Answer: Satellite
Explanation:
All automobiles uses satellite communication channel for their GPS devices.
Correct Answer: Water
Correct Answer: circle the wire in closed loops
Explanation:
Electric current produces a magnetic field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire.
Correct Answer: air high in the atmosphere
Explanation:
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth.
Middle latitude cyclones are fueled by air high in the atmosphere.
Correct Answer: near images are blurry
Correct Answer: Earth's core contains a large amount of iron
Explanation:
In physics, the dynamo theory proposes a mechanism by which a celestial body such as Earth or a star generates a magnetic field.
Earth's crust core contains a large amount of iron and nickel is the evidence of the dynamo theory.
Correct Answer: Violet
Explanation:
Violet colour has the highest energy. The higher the frequency, the faster the oscillations and thus the higher the energy. Therefore, the highest-frequency ultra-violet light or the lowest wavelength is violet.
Correct Answer: Power
Explanation:
Energy can be transferred from one system to the other. The rate at which energy is transferred from one system to other system is called POWER. Energy transferred in one second is called a watt.
Correct Answer: alloy and drop-forged steel
Correct Answer: Infrared radiation
Explanation:
Infrared radiation
