Answer:

Ohayo, Haruki-kun here!

The answer is, alcohol thermometer uses alcohol as the liquid to measure the temperature variations. Alcohol expands when it absorbs temperature and contract in colder temperatures. Most commonly used alcohol in these is ethanol, but different types of alcohols can be used depending on the measured temperature and environment in which the measurements are taken.

An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. The average speed of the

Norma-Jean [14]

Answer:

1083.173 km

Explanation:

Speed of longitudinal waves = 9.1 km/s

Speed of transverse waves = 5.7 km/s

Time taken by the longitudinal wave is t

Time taken by the transverse wave is t+71

Distance = Speed × Time

Distance traveled by the longitudinal wave

$\text{Distance}=9.1t$

Distance traveled by the transverse wave

$\text{Distance}=5.7(t+71)$

Since both distances are equal

$9.1t=5.7(t+71)\\\Rightarrow 9.1t-5.7t=404.7\\\Rightarrow 3.4t=404.7\\\Rightarrow t=\frac{404.7}{3.4}=119.03\ s$

The time taken by the longitudinal wave is 119.03 seconds

Distance traveled by the longitudinal wave

$9.1t=9.1\times 119.03=1083.173\ km$

The earthquake is 1083.173 km away

A spaceship is moving past us at a speed close to the speed of light. how would we view time (clocks) on the spaceship as it goe

SVEN [57.7K]

The clocks on the spaceship move more slowly than ours do.

<h3>What use does a spaceship serve?</h3>

A spaceship is a machine or vehicle built to travel through space.

Spacecraft are a form of artificial satellite used for a wide range of tasks, such as communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and cargo and person transfer.

<h3>What is a spaceship used for?</h3>

A launch vehicle from Earth can launch a spaceship, which is made to go in space.

In order to complete a mission—with or without people—and then return to Earth, it may carry a payload. building up.

<h3>How many spacecraft have traveled there?</h3>

Since humankind first started exploring beyond Earth's atmosphere in 1958, more than 250 robotic spacecraft—and 24 humans—have traveled into space.

In some applications of ultrasound, such as its use on cranial tissues, large reflections from the surrounding bones can produce

worty [1.4K]

Answer:

b. 0.75 mm

Explanation:

The distance between antinodes d is half the wavelength $\lambda$ . We can obtain the wavelength with the formula $v=\lambda f$ , where f is the frequency given ( $f=1MHz=1\times10^6Hz$ ) and v is the speed of sound in body tissues (v=1540m/s), so putting all together we have:

$d=\frac{\lambda}{2}=\frac{v}{2f}=\frac{1540m/s}{2(1\times10^6Hz)}=0.00077m=0.77mm$

which is very close to the 0.75mm option.

2. A string with a length of 0.9m that is fixed at both ends

aliina [53]

Answer:

2a.) Wavelength = 1.8 m

2b.) F = 66.67 Hz

3a.) Find the attached file

3b.) Wavelength = 0.6 m

Explanation:

Given that the

Length L = 0.9m

Wavelength (λ) = 2L/n

Where n = number of harmonic

If n = 1, then

Wavelength (λ) = 2L = 2 × 0.9 = 1.8 m

b.)

If waves travel at a speed of 120m/s on this string, what is the frequency

associated with the longest wave (first harmonic)?

Given that V = 120 m/s

V = Fλ

But λ = 2L, therefore,

F = V/2L

F = 120/1.8

F = 66.67 Hz

3. b.) If there are two node, the position will be in 3rd position which is 3rd harmonic

Using the same formula,

Wavelength (λ) = 2L/n

Where n = 3

Wavelength (λ) = 2 × 0.9/3

Wavelength (λ) = 0.6 m
