Answer 2

Calculating the Weight of the Wooden Block

To calculate the weight of the wooden block, we can use the principle of buoyancy. The buoyant force acting on the block is equal to the weight of the water displaced by the block. The buoyant force can be calculated using the formula:

Buoyant force = Weight of water displaced

Given that the wooden block displaces 0.5 liters of water, we can calculate its weight using this information.

Calculation

The weight of the wooden block can be calculated using the following steps:

1. Convert the volume of water displaced from liters to kilograms, as weight is typically measured in kilograms. 2. Use the density of water to convert the volume to weight.

Conversion and Calculation

1. Conversion from Liters to Kilograms: - 1 liter of water weighs approximately 1 kilogram. - Therefore, 0.5 liters of water displaced by the block weighs 0.5 kilograms.

2. Calculation of Weight of the Wooden Block: - The weight of the wooden block is equal to the weight of the water it displaces, which is 0.5 kilograms.

Therefore, the weight of the wooden block is 0.5 kilograms.
