"A block of metal weighs 40 N in air and 30 N in water. What is the buoyant force on the block due to the water? The density of water is 1000 kg/m3."

Respuesta :

Manetho

Answer:

buoyant force on the block due to the water= 10 N

Explanation:

We know that

buoyant force(F_B) on a block= weight of the block in air (actual weight) - weight of block in water.

Given:

A block of metal weighs 40 N in air and 30 N in water.

F_B =  40-30= 10 N

therefore,  buoyant force on the block due to the water= 10 N

The buoyant force on the block due to the water is 10 N.

The given parameters:

  • weight of the block in air, = 40 N
  • weight of the block in water, = 30 N
  • density of water, ρ = 1000 kg/m³

The buoyant force on the block due to the water is calculated as follows;

  • Buoyant force = weight in air - weight in water
  • Buoyant force = 40 N - 30 N
  • Buoyant = 10 N

Thus, the buoyant force on the block due to the water is 10 N.
