Explanation:

Answer 2

1. The process of loosening the soil is called tilling.

• Reducing the tightness and firmness of the soil is essential before the seeds are sown.
• The process is called tilling or plowing.
• It aerates the soil and improves the soil's absorption quality.

2. Force can be measured by mass.

• The force felt by a body is directly related to its mass.
• It is the product of the mass and acceleration of that body.

3. Rabi crop is harvested by the end of March.

• Rabi crops grow in the winter season.
• The seeds require a warm climate to germinate well.
• So it is essential to harvest the crops before the next sowing season.

4. Aneroid barometer has no liquid.

• It is a device that is used to measure air pressure.
• It is preferred more than a barometer with mercury.
• Lack of liquid makes it convenient as well as gives it a smaller size.
