You are operating a powerboat at night. You see green and white lights on another boat. What should you do?
iVinArrow [24]

Answer:

Just maintain the course you are on and your speed.

Explanation:

When you see a green and a white light, then from the port (left) side you will start coming across another craft. You are the stand-alone craft in this scenario and therefore should stay consistent with your pace and direction. The other craft must take important and early measures to keep the craft away from you.

What is the difference between elastic force and gravitational force?
3241004551 [841]
There are four fundamental forces. Gravitational is one. Elastic is produced by Electrostatic Force( a different fundamental force!)
Gravity has an infinite range. Elecrotrostatic forces reduce significantly as charges move away small distances but are relatively strongly felt. We feel the forces pulling on us when we stretch rubber. But two large balls side by side will not be significantly attracted by their tiny gravitational forces!

S A pulse traveling along a string of linear mass density μ is described by the wave function
HACTEHA [7]

The power P(x) carried by this wave at a point x = P(x) = (μ ω³ A² e⁻²ᵇˣ)/2k

Power time is the pace at which work is completed or energy is delivered; it is expressed as the product of the work completed (W) and the energy transferred (t), or W/t. The variation in the gas pressure ΔP measured from the equilibrium value is also periodic with the same wave number and angular frequency as for the displacement which is given by

ΔP = ΔPmax sin (kx−ωt)

Power is an expression of energy expended through time (effort), of which force is an element, as opposed to force itself, which is the fundamental outcome of an interaction between two objects. Power can be measured and described, but a force is a real physical entity, but power is not. ​The power is the rate at which the piston is doing work on the element at any instant of time is given by

Power = F ⋅ v

As we mention before in the concept session, the power of the wave is given by

P = ρ ν ω² A s² sin(kx-ωt)

P(x) = 1/2 μ ω² ν A²

      = 1/2 μ ω² ω/2 A² e⁻²ᵇˣ

P(x) = (μ ω³ A² e⁻²ᵇˣ)/2k

So, The final answer of power P(x) is P(x) = (μ ω³ A² e⁻²ᵇˣ)/2k.
