The answer is Reflection

This property of a wave is reflection.
Reflection of a wave is the process by which waves such as light, sound , infrared, or radio waves, hits and object and bounces off it. It is the change in direction of a wave front at an interface between two different media so that the wavelength returns into the medium of origin. From the law of reflection for a specular reflection the angle at which the wave is incident on the surface is equal to the angle at which it is reflected.

With a mass of 109 kg, Baby Bird is the smallest monoplane ever

OLga [1]

Total resultant velocity=5.11-3.27=1.84m/s

m_1=61.4kg
m_2=109kg
v_1=1.84m/s
v_2=?

$\\ \sf\longmapsto ∆P=P$

$\\ \sf\longmapsto m_1v_1=m_2v_2$

$\\ \sf\longmapsto v_2=\dfrac{m_1v_1}{m_2}$

$\\ \sf\longmapsto v_2=\dfrac{61.4(1.84)}{109}$

$\\ \sf\longmapsto v_2=112.976/109$

$\\ \sf\longmapsto v_2\approx 1.3m/s$

A tennis ball is thrown from a 25 m tall building with a zero initial velocity. At the same moment, another ball is thrown from

Nataly [62]

Answer:

The two balls meet in 1.47 sec.

Explanation:

Given that,

Height = 25 m

Initial velocity of ball= 0

Initial velocity of another ball = 17 m/s

We need to calculate the ball

Using equation of motion

$s=ut+\dfrac{1}{2}gt^2+h$

Where, u = initial velocity

h = height

g = acceleration due to gravity

Put the value in the equation

For first ball

$s_{1}=0-\dfrac{1}{2}gt^2+25$ ....(I)

For second ball

$s_{2}=17t-\dfrac{1}{2}gt^2+0$ ....(II)

From equation (I) and (II)

$-\dfrac{1}{2}gt^2+25=17t-\dfrac{1}{2}gt^2+0$

$t=\dfrac{25}{17}$

$t=1.47\ sec$

Hence, The two balls meet in 1.47 sec.
