The correct answer to the question is parallel.

EXPLANATION:

Before answering the question, first we have to understand a longitudinal wave.

A longitudinal wave is a type of mechanical wave in which the particle vibration is parallel to the direction of wave propagation.

In this type of wave, one will find compression and rarefaction . Compression is the high pressure region where particles are closely aggregated to each other while rarefaction is the low pressure region where particles are far away from each other. Hence, a longitudinal wave is a series of compression and rarefaction.

The transfer of energy occurs from particle to particle. On the other hand, we may say that transfer of energy takes place from compression to rarefaction, and this process is repeated.

Hence, the longitudinal waves transfer energy parallel to the direction of the wave motion.

jack be nimble jack be quick jack jumped over the candlestick with a velocity of 5.0 m/s at an angle of 30.0 degrees to horizont

Mrrafil [7]

Answer:

Explanation:

The vertical component of Jack's initial velocity is:

5.0

⋅

sin

∘

5.0

⋅

2.5

m/s

With gravitational acceleration

9.8

m/s

, he will reach the highest point of his trajectory after:

2.5

9.8

≈

0.255

The average vertical component of his velocity in that

0.255

will be:

⋅

2.5

1.25

m/s

So the highest point of his trajectory will be:

0.255

⋅

1.25

≈

0.32

So he will pass approximately

above the top of the candle.

The horizontal component of his velocity will be a constant:

5.0

√

≈

4.33

m/s

So Jack's trajectory will be substantially longer than it is high and he will spend little time anywhere near above the candle.

Physics !!!!!!!!!!!!!!!!!

madreJ [45]

Answer:

1) v = -0.89 m/s

2) v = 36.5 m/s

Explanation:

1) Given

The mass of the boy, M = 45 Kg

The mass of the skateboard, m = 2 Kg

The initial velocity of the boy and skateboard is zero

According to the law of conservation of linear momentum

MV + mv = 0

V = - mv/M

Substituting the given values in the above equation

V = -2 x 20/ 45

= -0.89 m/s

Hence, the velocity of the boy, v = -0.89 m/s

2) Given

The mass of the boy, M = 47 Kg

The mass of the skateboard, m = 8 Kg

The initial combined velocity of the boy and skateboard, u = 4.2 m/s

The boy jumped off from the skateboard with velocity, V = -1.3 m/s

According to the law of conservation of momentum,

MV + mv = (M + m)u

v = [(M + m)u - MV] / m

Substituting the given values,

v = [(47 + 8)4.2 - 47(-1.3)] / 8

= 36.5 m/s

Hence, the velocity of the skateboard, v = 36.5 m/s

The time taken for an object to fall from a height of h m from the earth'fs surface is t s.

telo118 [61]

Answer:

B. Longer than t s,

Explanation:

Gravitational accln on earth is 9.8 m/s^2,

and one you provided as on moon is 1.6 m/s^2

that mean on moon gr. accl. is lesser!

now the time taken on earth will be lesser cuz from the same height if you drop the object from rest!

since accln on earth is higher,the object will attain higher velocity as compare to that of on moon!

Which of the following is not an example of convection? Warm air rising from heated pavement The rolling motion of boiling water

Romashka-Z-Leto [24]

Answer: The handle of a frying pan on the stove

Explanation: Convection is the heat transfer done by the movement of a fluid, or the molecules on it. This can happen by the change on density from fluids, when a fluid tempeture rise, it expands, rising his volumen and decreasing his density. When this happens the fluid becomes lighter, so it moves.

The handle of a frying pan gets hotter but no molecular movement is done. It is between the same material there is a energy transfer from the source to the rest of the pan. This is called Conduction.
