A thermometer that uses a liquid to measure temperature works because

Answers

Answer 1

Answer: The liquid in a thermometer is sometimes colored alcohol but can also be a metallic liquid called mercury. Mercury and alcohol expand when heated and shrink when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. That's how a thermometer that uses liquid to measure temperature.

Answer 2

Answer: a rule of thumb is that liquid expands when heated, so when liquid is in a given space one can measure how far the liquid moves when it gets heated.

The weight of a body in earth is 29N. Find the mass?

Answers

Hi!

The weight force is given by: F = mg (mass x gravity)

Then, we have:
29 = m * 9.8
29/9.8 = m
m = 2.95 kg

Which term refers to the time interval between the passage of successive wave crests? a. wave height
b. wave period
c. wave speed
d. wavelength

Answers

I believe the correct answer from the choices listed above is option B. The term that refers to the time interval between the passage of successive wave crests would be wave period. It is the time for a particle on a medium to make one complete vibrational cycle.

Solve the following automotive-services problem.Voltage = 220 v
Current = 4 amps
Resistance =

Answers

Explanation:

Given that,

Voltage, V = 220 V

Current, I = 4 A

We have to find the resistance of the appliance.

Ohm's law gives the relation between the current, resistance and the voltage.

V = I R, R = resistance

So, $R=(V)/(I)$

$R=(220\ V)/(4\ A)$

$R=55\ \Omega$

Resistance of the appliance is $55\ \Omega$ .

Hence, this is the required solution.

Resistance = (voltage) / (current)

= (220 V) / (4 A) = 55 ohms .

(Where exactly do you use 220 V in your car ? ! ?)

A. Destructive interference
B. Diffraction subtraction
C. Diffraction gradient
D. Constructive interference

Answers

Answer: Constructive interference

Explanation: Just took the test

Final answer:

The diagram shows destructive interference between two waves, resulting in a smaller amplitude wave.

Explanation:

The type of wave interaction shown in the diagram is destructive interference.

In destructive interference, two waves combine and create a new wave with a smaller amplitude. This occurs when the crests of one wave align with the troughs of another wave, causing cancellation.

In the diagram, wave A and wave B are out of phase, meaning their crests and troughs do not align. When they combine, the resulting wave has a smaller amplitude than either individual wave, indicating destructive interference.
