a. The formula for an object&#039;s weight, W, is given as W=mg, where m is the object&#039;s mass and g is the acceleration brought on by a location&#039;s gravity. We are aware that the acceleration brought on by gravity varies from planet to planet. As a result, an object&#039;s weight varies between planets.b. The following precautions should be followed to collect accurate measurements in daily activities:1. The measurement equipment should be adequate and in good functioning order.2. It is important to utilize the tool correctly.3. It is important to verify that the department of weights and measures has given the device in use a stamp of standardization.4. For measuring accuracy, 3–4 measurements should be collected.

(c) Mass: 1. The quantity of matter a body contains is measured by its mass.2. A body&#039;s mass is an inherent quality.3. Everywhere in the cosmos, a body has the same mass.4. A body cannot have zero mass.5. The kilogram is the SI unit of mass (kg).6. Both a beam balance and a pan balance may be used to calculate the mass of a body.Weight:1. Weight is the force that a body experiences as a result of another body&#039;s gravitational attraction, such as the sun, the moon, or the Earth.2. A body&#039;s weight is an external characteristic.3. A body&#039;s weight is determined by the local acceleration brought on by gravity in the area where it is positioned.4. A body&#039;s weight may be zero.5. The SI unit for weight is a newton since it is a force (N).6. Both a spring balance and a weighing machine may be used to determine the weight of a body.
