Using the information from Paul Hewitt's Conceptual Development Practice Page 25-1 and the image below, answer the following question.Image of a wave with two rulers, one vertical and one horizontal, measuring the wave is shown. The wave's first crest aligns from 0 to just less than 4 centimeters on the horizontal ruler and rises from the equilibrium located at 5 centimeters to just before 3 centimeters. The wave's first trough aligns continues to just less than 8 centimeters on the horizontal ruler and goes down from the equilibrium located at 5 centimeters to just before 7 centimeters.What was the measurement of the wavelength and amplitude respectively?

Answers

Answer 1

Answer:

Answer:

A = 2 cm, λ = 8 cm

Explanation:

The amplitude of a wave is the maximum height it has, in this case the height is measured by the vertical ruler,

We are told the balance point is in the reading of 5 cm, that the maximum reading is 3 cm and the Minimum reading is 7 cm. Therefore, the distance from the ends of the ridge to the point of equilibrium is

d = 7-5 = 2 cm

d = 5-3 = 2 cm

A = 2 cm

The wavelength is the minimum horizontal distance for which the wave is repeated, that is measured by the horizontal ruler.

The initial reading for 4 cm and the final reading for 8 cm, this distance corresponds to a crest of the wave, the complete wave is formed by two crests whereby the wavelength is twice this value

Δx = 8-4 = 4 cm

λ = 2 Δx

λ = 8 cm

You put a piece of ice into a glass of lemonade at room temperature. Which statements explains the heat flow in this scenario? A. Heat flows in both directions. B. Heat flows from the ice to the lemonade. C. Heat flows from the lemonade to the ice. D. Heat flows from the ice to the lemonade to the glass.

Answers

Answer:

C. Heat flows from lemonade to the ice

Explanation:

Transfer of heat from the drink to the ice is what melts the ice and cools the drink.

as you are leaving a building, the door opens outward. if the hinges on the door are on your right, what is the direction of the angular velocity of the door as you open it?

Answers

The correct answer for the question that is being presented above is this one: "B) down." As you are leaving a building, the door opens outward. if the hinges on the door are on your right, the angular velocity of thedoor as you open it us 'down.'

Here are the following choices:
A) up
B) down
C) to your left
D) to your right

Which type of waves is important to have for a surfer who wants to do aerial maneuvers? A. Plunging waves B. Surging waves C. Orbital waves D. Spilling waves

Answers

Plungingwaves is important to have for a surfer who wants to do aerial maneuvers.

The correct options is A.

What is a plunging wave?

When the ocean floor is steep or has abrupt depth changes, crashingwaves occur. They could be large close-outs or strong barrels. Combining pouring and plungingwaves creates a collapsing wave.

What causes plunging waves to form?

When the incoming surf strikes a steep ocean floor or a sea bottom with abrupt depth changes, plungingwaves are created. The wave's peak curves over and erupts on the trough as a result. A crashing sound is frequently audible due to the compression of the airbeneath the wave's lip.

#SPJ2

Aerial maneuvers in surfing demand taking the surfboard into the air. The best type of waves for such maneuvers are:

- the section of a wave coming towards you should be smaller than the section you are on

- you should try to find closeout sections of waves ( formations that do not allow a tubular ride )

- the wave should be either wedging or bowling in towards you, it should not be a straight wave.

What causes an electric current in a wire? A.
Electric fields cause atoms to move in the wire.

B.
Electrons flow because of electrical attraction and repulsion.

C.
Electrons move because of heat.

D.
Electrons build up in the wire and create a charge

Answers

The correct answer is B. Electrons flow because of electrical attraction and repulsion.

Answer:

Electrons flow because of electrical attraction and repulsion.

Explanation:

What is not needed for a charge to flow through a conducting wire?A. an electrical insulator

B. a wire connected in a complete loop

C. a source of electrical energy

Answers

Answer: The correct answer is an electrical insulator.

Explanation:

Insulator : It is a material which resists the flow of electrons. It has high resistance in comparison to the conductor.

Conductor: It is a material which allows the flow of electrons. It has low resistance in comparison to the conductor.

Battery is a source of electrical energy. It forces the electrons to flow. The rate of flow of electrons constitutes the current.

In the given problem, an electrical insulator is not needed for a charge to flow through a conducting wire.

To design the circuit and to make a current flow in the circuit, a battery, a wire connected in a complete loop and a source of electrical energy are needed.

Therefore, the correct option is (C).

An electrical insulator would not be needed for a charge to flow through a conducting wire.

Answer: Letter A
