Um avião, após deslocar-se 120 km para nordeste (NE), desloca-se 160 km para sudeste (SE). Sendo um quarto de hora o tempo total
Svetach [21]

Answer:

E) 800 km/h

Explanation:

The computation of the average vector velocity module of the plane, at that time is shown below:

The displacement vector is

d^2 = d1^2 + d2^2

where,

d1 = northeast displacement

d2 = southeast displacement

Now

d^2 = (120)^2 + (160)^2

= 14400 + 2560

= 40000

= √40000

d = 200 km

Now the average velocity is

V = ΔS ÷ Δt

= 200 ÷ 1 ÷ 4

= 200 × 4

=  800 km/h

Answer:

wave A

Explanation:

shortest wavelength carry the most energy

more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave.

Give a flow chart of how the inlet and exhaust valve operate in the internal combustion engine of a tractor.
abruzzese [7]

Flow chart of a system is a diagrammatic representation of how that system performs it's functions.

<h3>The flow chart of internal combustion engine</h3>

The flow chart of internal combustion engine is the diagrammatic representation of how the engine works.

The inlet valve of the engine is the valve that allows for the entry of fuel-air mixture into the engine.

The exhaust valve of the engine is the allows for the outflow of used gases from the engine.

From the attached flow chart, Intake valves are opened to allow the flow of an air/fuel mixture into the engine's cylinders prior to compression and ignition, while exhaust valves open to permit the expulsion of exhaust gases from the combustion process after ignition has occurred.

LuckyWell [14K]

Answer:

a) the frequency of the wave is 0.2 Hz

b) the speed of the wave 4 m/s

Explanation:

Given that;

time period = to complete one cycle t = 5 sec

frequency f = 1/t

frequency f = 1 / 5sec

f = 0.2 Hz

Therefore the frequency of the wave is 0.2 Hz

b)

speed of wave V = λf

given that our wavelength is 20.0 m

we substitute

speed of wave V = 20.0 × 0.2

speed of wave V = 4 m/s

Therefore, the speed of the wave 4 m/s
