How does destructive interference affect the amplitude of a wave?

1 answer:

4 0

the displacement of a trowel is equal in magnitude to that of a peak but it is negative so the sum of the displacement will be 0 the amplitude is reduced to zero so the answer is B the amplitude can decrease. Hope this helps my friend :)

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, t

bekas [8.4K]

Answer:

0.13 m/s

Explanation:

$m_1$ = Mass of first car = 140000 kg

$m_2$ = Mass of second car = 95000 kg

$u_1$ = Initial Velocity of first car = 0.3 m/s

$u_2$ = Initial Velocity of second car = -0.12 m/s

$v$ = Velocity of combined mass

For elastic collision

$m_1u_1 + m_2u_2 =(m_1 + m_2)v\\\Rightarrow v=\frac{m_1u_1 + m_2u_2}{m_1 + m_2}\\\Rightarrow v=\frac{140000\times 0.3 + 95000\times -0.12}{140000+ 95000}\\\Rightarrow v=0.13\ m/s$

Their final velocity is 0.13 m/s

A bowling ball and a soccer ball are both rolling at the same speed. Which has more kinetic energy and why?

MissTica

Ek = 1/2 mv^2

If they are travelling at the same speed the one with the larger mass will have more kinetic energy as kinetic energy and mass are proportional.

A 1.00 -kg object slides to the right on a surface having a coefficient of kinetic friction 0.250 (Fig. P8.62a). The object has

LekaFEV [45]

The distance D where the object comes to rest is 1.08.m.

<h3>What is the distance?</h3>

The separation of one thing from another in space; the distance or separation in space between two objects, points, lines, etc.; remoteness. The distance of seven miles cannot be accomplished in one hour of walking.
Learn how to use the Pythagorean theorem to get the separation between two points using the distance formula. The Pythagorean theorem can be rewritten as d==(((x 2-x 1)2+(y 2-y 1)2)
The distance between any two places is the length of the line segment separating them. By measuring the length of the line segment that connects the two points in coordinate geometry, the distance between them may be calculated.

$W_{total} =$ ΔKE ⇒ -0.25*1*9.8*D = 0-1/2*1* $2.3^{2}$

⇒ $D=\frac{0.5*2.3^{2} }{2.45}$

⇒1.08.m
