A pipe that is open at both ends and a tuning fork of frequency 240 Hz are being used as a fancy new thermometer, albeit one tha

garri49 [273]

Answer:

9.51 Hz

Explanation:

f₀ = frequency of tuning fork and fundamental frequency of the pipe initially = 240 Hz

T₀ = Room temperature = 20 °C

v₀ = speed of sound at room temperature

speed of sound at room temperature is given as

v₀ = 331 + (0.6) T₀ = 331 + (0.6) (20) = 343 m/s

L₀ = Length of the pipe

For open pipe, we have

v₀ = 2 L₀ f₀

343 = 2 (240) L₀

L₀ = 0.715 m

T = new temperature = 43.0°C

v = speed of sound at new temperature

speed of sound at new temperature is given as

v = 331 + (0.6) T = 331 + (0.6) (43) = 356.8 m/s

L = length of pipe = L₀ = 0.715 m

f = new fundamental frequency

For open pipe, we have

v = 2 L f

356.8 = 2 (0.715) f

f = 249.51 Hz

Δf = Beat frequency

Beat frequency is given as

Δf = f - f₀

Δf = 249.51 - 240

Δf = 9.51 Hz

Mark all the quarks.a) Proton b) Electron c)Anti-top d) Gluon e) Tau Neutrino

djverab [1.8K]

Answer:

(a) Proton, (c) Anti- top

Explanation:

Elementary particles are the particles without any sub-structure which means they are not composed of other particles.

The elementary particles are classified into three categories which are discussed below:

(1) Quarks: up, down, top, bottom, strange, and charm.

(2) Leptons: electrons, electron neutrino, muon, muon neutrino, tau, tau neutrino.

(3) Bosons: Guon, photons Z bosons, W bosons, Higgs.

The bottom is a quark which is also can be called anti-top. And proton consist of two up quarks and one down quark so it is also categorized in the quarks.

Therefore, proton, and anti top are categorized in the quarks.

Look at Concept Simulation 5.2 to review the concepts involved in this question. Two cars are identical, except for the type of

dimulka [17.4K]

Answer:

Tread design on car B would yield a larger coefficient of static friction between the tires and the road

Explanation:

The car model using the coefficient of static friction doesn't work well with tires. A higher coefficient of static friction would require more force to cause a loss of attraction.

The static frictional force helps to keep the unbanked horizontal turn. This means that the frictional force is the centripetal force.

The tread design of car B ensures that the centripetal force is enough to negotiate the turn. On the other hand, the tread design of car A does not provide the necessary centripetal force, hence car A is unable to negotiate the turn.

Therefore, tread design on car B would yield a larger coefficient of static friction between the tires and the road.
