Answer 2

Length of the Rubber Band with a Load

To find the length of the rubber band with a load, we need to consider the initial length of the rubber band and the increase in length when a load is attached.

Given: - Initial length of the rubber band: 15 cm - Increase in length when a load is attached: 3 cm

To find the length of the rubber band with the load, we add the increase in length to the initial length:

Length of the rubber band with the load = Initial length + Increase in length Length of the rubber band with the load = 15 cm + 3 cm Length of the rubber band with the load = 18 cm

Therefore, the length of the rubber band with the load is 18 cm.

Units of Measurement for Elastic Force

The force of elasticity, or the force exerted by a stretched or compressed object, is measured in units called Newtons (N). Newton is the standard unit of force in the International System of Units (SI).

Therefore, the force of elasticity is measured in Newtons (N).

Force of Gravity on an Object with a Mass of 500 grams

To calculate the force of gravity on an object, we need to multiply the mass of the object by the acceleration due to gravity.

Given: - Mass of the object: 500 grams

To calculate the force of gravity, we need to convert the mass from grams to kilograms, as the standard unit for mass in the SI system is kilograms.

Mass of the object in kilograms = Mass of the object in grams / 1000 Mass of the object in kilograms = 500 grams / 1000 Mass of the object in kilograms = 0.5 kg

The acceleration due to gravity is approximately 9.8 m/s^2.

Force of gravity = Mass of the object * Acceleration due to gravity Force of gravity = 0.5 kg * 9.8 m/s^2 Force of gravity = 4.9 N

Therefore, the force of gravity acting on an object with a mass of 500 grams is 4.9 Newtons (N).
