Answer:1.2 m/s

Explanation:

mass of ball`(m_1)=2 kg`

initial Velocity of m_1=3 m/s`

mass of another ball (m_2)=2 kg`

initial velocity of m_2=0`

Conserving momentum

m_1u_1+m_2u_2=(m_1+m_2)v`

2\times 3+2\times 0=(2+3)v`

v=\frac{6}{5}=1.2 m/s`

A brick is 32cm long and 10cm wide. It weighs 16N and is lying on the ground. Find the pressure exerted by the brick on the grou
Vaselesa [24]

Answer:

Below

Explanation:

First, we need to convert the dimension from cm to m before plugging it into the equation:

     32 / 100 = 0.32 m

     10 / 100 = 0.1 m

You can use this equation to find the pressure exerted on the ground

     Pressure = Force / Area

Plugging our values in.....

     Pressure = 16 Newtons / (0.1)(0.32)

                     = 16 Newtons / 0.032

                    = 500 N/m^2

Hope this helps! Best of luck <3

A source emits monochromatic light of wavelength 495 nm in air. when the light passes through a liquid, its wavelength reduces t
Katyanochek1 [597]
By definition, the refractive index is
n = c/v
where c =  3 x 10⁸ m/s,  the speed of light in vacuum
v = the speed of light in the medium (the liquid).

The frequency of the light source is
f = (3 x 10⁸ m/s)/(495 x 10⁻⁹ m) = 6.0606 x 10¹⁴ Hz

Because the wavelength in the liquid is 434 nm = 434 x 10⁻⁹ m, 
v = (6.0606 x 10¹⁴ 1/s)*(434 x 10⁻⁹ m) = 2.6303 x 10⁸ m/s

The refractive index is (3 x 10⁸)/(2.6303 x 10⁸) = 1.1406

What is inside of a blackhole ?
horsena [70]
We don't know. A black hole is a star that has collapsed into its own gravity. The gravity in fact, is so strong that even light cannot get through it. That's why it looks black to us.
