The correct answer to the question is : Transverse wave.

EXPLANATION :

Before going to answer this question, first we have to understand the longitudinal and transverse wave.

LONGITUDINAL WAVE : A longitudinal wave is a mechanical wave in which the direction of vibration of particles is parallel to the direction of wave propagation. It moves in the form of compression and rarefaction.

For instance, sound wave.

TRANSVERSE WAVE : A transverse wave is a mechanical wave in which the direction of vibration of particles is perpendicular to the direction of wave propagation. It moves in the form of crests and troughs.

For instance, the wave created in a pond when a stone is dropped into it.

Hence, the correct answer of this question is transverse wave.

One of Lex Luthor's henchman attacks Superman, shooting a rapid-fire stream of 3.3 g bullets at him at a rate of 112/min. The sp

igor_vitrenko [27]

Answer:

3.2451N

Explanation:

Mass of the bullet (m) $= 3.3g = 3.3*10^{-3}Kg$

Speed of the bullet (V) $= 527m/s$

Rate of bullet (r) $= 112/min = 1.866\sec$

We can calculate with this information the average acceleration of bullets

$a=V*r = 527\frac{m}{s}\frac{1.866}{s} = 983.38m/s^2$

The force is given by,

$F=ma\\F=(3.3*10^{-3})*983.38m/s^2 = 3.2451N$

That is just because he is Superman.

The horizontal bar rises at a constant rate of three hundred mm/s causing peg P to ride in the quarter circular slot. When coord

SVETLANKA909090 [29]

Answer:

Explanation:

Given

Horizontal bar rises with 300 mm/s

Let us take the horizontal component of P be

$P_x=rcos\theta$

$P_y=rsin\theta$

where $\theta$ is angle made by horizontal bar with x axis

Velocity at y=150 mm

$150=300sin\theta$

thus $\theta =30^{\circ}$

position of $P_x=rcos\theta =300\cdot cos30=300\times \frac{\sqrt{3}}{2}$

$P_x=259.80 mm$

$P=259.80\hat{i}+150\hat{j}$

Velocity at this instant

$u_x=-rsin\theta =300\times sin30=-150 mm/s$

$u_y=rcos\theta =300\times cos30=259.80 mm/s$

What changes might you expect to see in the earth's general circulation if the earth's rotation were in the opposite direction?

Nonamiya [84]

With the earth’s current rotation, the major pressure systems of the general circulation can be correlated with the increase and decrease of air. When there is a considerable amount of air, precipitation will become present on a large scale. When there is less air, then there is an increase in chances of an area becoming dry. According to our textbook, a decrease in air on the eastern margin (west coast) creates a subsidence inversion. This causes dry weather. On the western margin (east coast) the humidity in the air rises, condenses and creates rain fall. So if the earth were to rotate in the opposite direction, we could possibly expect weather on the west coast to produce more rain and the weather on the east coastto become dry.
-I hope this helped!
