The correct choice is

a solenoid

a solenoid is a sequence of a number of loops in the form of a helix in which when current flows, a magnetic field is produced along the axis of the solenoid. The magnetic field thus produced by a solenoid is given as

B = μ₀ n i

where B = magnetic field , n = number of turns per unit length, i = current in the solenoid.

A solid 200-g block of lead and a solid 200-g block of copper are completely submerged in an aquarium filled with water. Each bl

finlep [7]

Answer:

B. The buoyant force on the copper block is greater than the buoyant force on the lead block.

Explanation:

Given;

mass of lead block, m₁ = 200 g = 0.2 kg

mass of copper block, m₂ = 200 g = 0.2 kg

density of water, ρ = 1 g/cm³

density of lead block, ρ₁ = 11.34 g/cm³

density of copper block, ρ₂ = 8.96 g/cm³

The buoyant force on each block is calculated as;

$F_B = mg(\frac{density \ of \ fluid}{density \ of \ object} )$

The buoyant force of lead block;

$F_{lead} = 0.2*9.8(\frac{1}{11.34} )\\\\F_{lead} = 0.173 \ N$

The buoyant force of copper block

$F_{copper} = 0.2*9.8(\frac{1}{8.96})\\\\F_{copper} = 0.219 \ N$

Therefore, the buoyant force on the copper block is greater than the buoyant force on the lead block

The jet fuel in an airplane has a mass of 97.5 kg and a density of 0.804 g/cm3. What is the volume of this jet fuel

Mnenie [13.5K]

The volume of the jet fuel is 1.213 x 10⁵ cm³.

<h3>What is density?</h3>

Density is a physical property that measures the ratio of mass to volume occupied by an object.

Density = mass/volume

Volume = mass/density

<h3> Volume of the jet fuel</h3>

The volume of the jet fuel is calculated as follows;

Volume = (97500 g)/(0.804 g/cm³)

Volume = 1.213 x 10⁵ cm³

Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.
