There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in electrons moving from one surface to another.

Which example best illustrates the transfer of energy between two waves?
Pachacha [2.7K]

Answer:

Vibrations of electric and magnetic fields.

Vibration of air particles

Vibration of the water particles.

Explanation:

We have here two groups of waves. Electromagnetic wave and mechanical waves.

  1. For the first one, electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
  2. For the second group, mechanical waves as a sound, for instance, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. Or In water waves, energy is transferred through the vibration of the water particles.

I hope it helps you!

Lenses are described as convergent or divergent depending on how they refract light. What is the difference between these two ty
Umnica [9.8K]

Answer:

Explanation:

Convergent lens is the lens which converges the rays of light falling on it. It is thicker at the middle and thinner at the edges. It is also known as convex lens.

Divergent lens is the lens which diverge the rays of light falling on it. It is thinner at the middle and thicker at the edges. It is also called as concave lens.

A large aquarium of height 5 m is filled with fresh water to a depth of D = 1.80 m. One wall of the aquarium consists of thick p
Damm [24]

To solve the problem we will first start considering the Pressure given the hydrostatic definition of the product between the density, the gravity and the depth. We will define the area where the liquid acts and later we will use the definition of the force as a product between the pressure and the area to calculate the force given in the two depths. The gauge pressure at the depth x will be

(P-P_a)= \rho g x

This pressure acts on the strip of area

dA = 7.6dx

The force acting on that strip is given by,

dF = (P-P_a)dA

dF = \rho g xdA

dF = 7.6 \rho g x dx

To evaluate the force, we will then consider the integral of the pressure as a function of the Area, or the integral of the previously found terms.

F = \int_0^x 7.6 \rho g x dx

F = 3.8 \rho g x^2

Evaluating at the initial depth of 1.8m and the final depth of 4.4 we have then that,

F_{1.8} = 3.8 (998)(9.8)(1.8)^2 = 120416.28N

F_{4.4} = 3.8(998)(9.8)(4.4)^2 = 719524.46N

Therefore the Net force will be

F = F_{4.4}-F_{1.8}

F = 719524.46-120416.28

F = 599108.18N

How is Newton’s third law of motion involved when you jump straight upward?
Bad White [126]
<span>Newtons 3rd law of motion states that action and reaction are equal and opposite. How it applies in this statement is that when you jump straight upward you hit the floor and you experience an equal magnitude of force against your feet, because force always acts as a result of two objects and whenever forces occur they do so in pairs of equal magnitude acting in opposite directions. I hope this helps!</span><span>
