The major difference between transverse and longitudinal waves is the:

Marysya12 [62]

In transversal wave particles do not oscillate along the line of the wave propagation but oscillate up and down about their mean position as the wave travels.thus transverse wave is the one in which individual particles of the medium move about their mean position in a direction perpendicular to the direction of wave propprgation.
In longitutional waves the individual particles of the medium move in the direction parallel to the direction of the propprgation of the disturbance. The particles do not move from one place to another but the simply oscillate back and forth about their position of the rest.
HOPE IT HELPS.

An ideal incompressible fluid flows at 12 m/s in a horizontal pipe. If the pipe widens to twice its original radius, what is the

grandymaker [24]

Answer:

d) 3 m/s

Explanation:

As we know by equation of continuity

$A_1v_1 = A_2v_2$

here we have

$A_1 = \pi r^2$

$A_2 = \pi (2r)^2$

$A_2 = 4\pi r^2$

now from above equation we have

$\pi r^2 v_1 = 4\pi r^2 v_2$

$v_2 = \frac{v_1}{4}$

here we have

$v_1 = 12 m/s$

$v_2 = 3 m/s$

A uniform steel rod of length 0.9 m and mass 3.8 kg has two point masses of 2.3 kg each at the two ends. Calculate the moment of

polet [3.4K]

Answer: $2.4705\ kg.m^2$

Explanation:

Given

length of the rod is L=0.9 m

Mass of the rod m=3.8 kg

Point masses has mass of m=2.3 kg

Moment of Inertia of the rod about the center is

$\Rightarrow I_o=\dfrac{1}{12}ML^2$

Moment of inertia of combined system is the sum of rod and two point masses.

$\Rightarrow I=I_o+2mr^2$

$\Rightarrow I=\dfrac{1}{12}3.8\times 0.9^2+2\times 2.3\times \left(\dfrac{0.9}{2}\right)^2\\\\\Rightarrow I=1.539+0.9315\\\Rightarrow I=2.4705\ kg-m^2$
