An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. When the craft was stationary

, the tension in the cable was 7000 N. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N drag force.

The tension in the cable when the craft was being lowered to the
seafloor = <span>7500 N - 1800 N = 5700 N</span>

I think you gave an incomplete question. The two questions would be:

A.What was the tension in the cable when the craft was being lowered to the seafloor? 

<span>B.What was the tension in the cable when the craft was being raised from the seafloor?
</span>
The details for answering the question are already given.

A. Tension in the cable when
 the craft was being lowered to the seafloor = 7000 - 1800 newton
                                                                      = 5200 newton

B. Tension in the cable when
 the craft was being raised from the seafloor = 7000 + 1800 newton
                                                                       = 8800 newton.

Answer: 26.67 m/s

Explanation:

Given

Length traveled by the ball s=40\ m

Time taken to reach the goal post is t=3\ s

Initial velocity u=0\ m/s

Using the second equation of motion

\Rightarrow s=ut+\frac{1}{2}at^2\\\Rightarrow 40=0+\frac{1}{2}a(3)^2\\\Rightarrow a=\frac{80}{9}\ m/s^2\\

Now using

\Rightarrow v^2-u^2=2as\\\\\Rightarrow v^2-0=2\times \frac{80}{9}\times 40\\\\\Rightarrow v=\sqrt{\dfrac{80\times 80}{9}}=\dfrac{80}{3}\\\Rightarrow v=26.67\ m/s

The velocity of ball will be 26.67 m/s

Which type of foot PPE must you wear if electrical shock is ever a possibility with your job?
ira [324]
The appropriate PPE(personal protective equipment) to be worn for foot protection against electric shock is boots retrofitted with rubber soles. Rubber does not conduct electricity and so will safeguard against electric shocks.

Other personal protective equipment used in a lab or industry can include safety glasses, rubber gloves, protective clothing and masks and respirators. PPE goes hand in hand with personal behaviour, personal grooming and housekeeping.

Why is a steam burn more damaging than a burn from boiling water at the same temperature?
maksim [4K]
The phase change (from gas to liquid) that the steam undergoes right when it touches your skin releases a lot of energy right onto your skin so it burns a ton. The boiling water would just burn you until it reaches the same temperature as your skin.

For an investigation, a teacher dropped a metal bolt into a container of maple syrup and asked students to remove the bolt witho
Aneli [31]

<em>Choice-C</em> is the right one.

-- The bolt didn't react to the magnet, and just laid there.  That tells you that the bolt was made of a non-magnetic material.

-- The bolt didn't float. It went straight to the bottom.  That tells you that it's more dense than the fluid around it.
