According to Archimedes's principle when a body is immersed fully or partially in a liquid, it experiences an upward force that is equal to the weight of the fluid displaced by it therefore the mass of water displaced is equal to the mass of the ship.

Correct Option: B

According to Archimedes's principle when a body is immersed fully or partially in a liquid, it experiences an upward force that is equal to the weight of the fluid displaced by it therefore the mass of water displaced is equal to the mass of the ship.

The specific gravity of liquid is greater than one and as the specific gravity of water is 1 hence the level of liquid in the beaker will rise up.

Correct Option: C

The specific gravity of liquid is greater than one and as the specific gravity of water is 1 hence the level of liquid in the beaker will rise up.

produces the necessary acceleration of its motion in a curved path

Correct Option: D

produces the necessary acceleration of its motion in a curved path

Time period T = 2π √l/g. The time period of a pendulum depends on its length l and acceleration due to gravity g.

Correct Option: B

Time period T = 2π √l/g. The time period of a pendulum depends on its length l and acceleration due to gravity g.
