A deep draught vessel sailing in a very narrow channel can develop a sudden sheer as it slows down. What could be the cause of this?

Answers

Answer 1

Answer:

Final answer:

A deep draught vessel sailing in a narrow channel can experience a sudden sheer due to squat, which is the downward displacement caused by hydrodynamic forces in shallow water. This can lead to the ship sinking lower in water and potentially losing control. Ship operators should be aware of this phenomenon and take precautions when navigating in narrow channels.

Explanation:

A deep draught vessel sailing in a very narrow channel can develop a sudden sheer as it slows down due to the phenomenon called squat. Squat refers to the downward displacement of a ship caused by hydrodynamic forces when it is sailing in shallow water. As the vessel slows down, the decrease in speed leads to a decrease in the hydrodynamic forces supporting the ship, causing it to sink lower in the water and potentially lose control.

This sudden sheer can be dangerous as it can result in the ship deviating from its intended course and potentially colliding with the channel walls or disturbing other vessels in the vicinity.

It is important for ship operators to be aware of this phenomenon and take necessary precautions when navigating in narrow channels, such as maintaining a safe speed and keeping a proper distance from the channel walls.

Answer 2

Answer:

Final answer:

A deep draught vessel sailing in a very narrow channel can develop a sudden sheer as it slows down due to the change in pressure caused by the narrowing of the channel.

Explanation:

A deep draught vessel sailing in a very narrow channel can develop a sudden sheer as it slows down due to the change in pressure caused by the narrowing of the channel. When the channel narrows, there is a pressure difference which results in a net force on the fluid. This net force causes the vessel to experience a sudden sheer as it slows down.

the length of time it takes a planet to revolve around the sun is equivalent to witch of the following?

Answers

it really depends on how far or close the planet is from the sun

Answer:

The length of its year.

Explanation:

When Earth completes a full rotation, a year has completed. So, the same can be the same for other orbiting planet. The moon for example takes 29.5 days to revolve around the Earth, so one moon year is 29.5 Earth days.

At what speed v will the length of a 1.00 m stick look 13.7 % shorter (86.3 cm )Using formula L=Lp sqrt 1-v^2/c^2

Answers

L= Lp - 13.7*Lp/100 = Lp-0,137Lp = 0,8613Lp

⇒L/Lp = 0.8613

From the formula above L/Lp = √(1-v^2/c^2)

(L/Lp)^2 = 1 - (v^2/c^2)

v^2/c^2 = 1 - (L/Lp)^2

v/c = √[1 - (L/Lp)^2]

v = c √[1-(L/Lp)^2]

v =c√[1-0.8613^2] = 0.508c

In the vacumm speed of light, c, is approx 300,000,000 m/s

v =0.508 (300,000,000m/s) =152,400,000 m/s

Solar cells convert what type of enegry into electrical enegry

Answers

Solar cells convert Electromagnetic into electrical energy

Light cells?
If you are referring to solar panels, these convert light energy into electrical energy. They do so by generating “DC” (Direct Current) electricity from the light.This electricity is fed into a solar inverter that converts into “AC” (Alternating Current) electricity.The AC electricity is used to power appliances in your home.

what would be the final temperature of a mixture of 50g water at 20c temperature and 50g of water at 40c temperature?

Answers

Because there is the same amount of water in each sample, the samples have an equal amount of influence over the overall temperature. that means it will be somewhere right in the middle of the two original temperatures. The middle, also the average, of the two samples' temperatures is 30c, meaning that if you combined the 20c water and the 40c water the final result would be 100g of 30c water. If you need some more explanation, just ask.
