The design of boats is based on Archimedes' Principle, which states that the buoyant force on an object in water is equal to the weight of the water displaced. Suppose you want to build a sailboat whose hull is parabolic with cross section y ax2, where a is a constant. Your boat will have length L and its maximum draft (the maximum vertical depth of any point of the boat beneath the water line) will be H. Every cubic meter of water weighs 10.000 newtons. Required:
What is the maximum possible weight for your boat and cargo?

Maximum Possible weight  = HL] x 10,000 Newtons.

Explanation:

Solution:

Note: This question is incomplete, it lacks the sketch of the boat which is necessary to draw the volume equation. But I have found similar question and drawn the equation accordingly and solved the question.

In order to find the maximum possible weight for your boat and cargo,  we need to solve this definite integral equation of volume.

V = 2L

With limits 0 and

Putting the Limits into the variable x, we will get.

V = 2L

Solving the above equation further,

V = 2HL]

V = 2HL]

So, final equation of the volume after the integration is:

V = HL]

Now, we know that Every cubic meter weighs 10,000 newtons. So,

Maximum Possible weight  = HL] x 10,000 Newtons.

the answer for apex is the lowest

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
