The milky way Galaxy is our own Galaxy in which our planet earth along with other planets and the Sun comprising the Solar system, exists.

You hold a small metal ball of mass a height above the floor. You let go, and the ball falls to the floor. Choose the origin of
baherus [9]

Answer:

yᵢ = h

vᵢᵧ = 0

Explanation:

Let initial velocity = u

     final velocity = v

     height = h

     acceleration due to gravity = g

Therefore fro equation of motion,

v^{2}=u^{2}+2gh

Here initial velocity is zero.

Hence, v^{2}=2gh

v = \sqrt{2gh}

but since it points downward and you positive is taken in the up direction

v = -\sqrt{2gh}

Why do you think sound travels faster in steel than it does in wood? (Hint: Think about the densities of the two materials, and
Crazy boy [7]

Answer:

If sound waves of the same energy were passed through a block of wood and a block of steel, which is more dense than the wood, the molecules of the steel would vibrate at a slower rate. Sound moves faster through denser air because the molecules are closer together in dense air and sound can be more easily passed on.

Light with a wavelength of λ = 689 nm. is incident on a single slit of width w = 3.75 micrometers. A screen is located L = 0.65
rodikova [14]

Answer:

119.42 x 10⁻³ m

Explanation:

The distance of first dark fringe from central bright spot will be equal to the width of fringe .

Fringe width = λL /w

where λ is wavelength of light, w is slit width , L is distance of screen .

So required distance

= \frac{689\times10^{-9}\times0.65}{3.75\times10^{-6}}

= 119.42 x 10⁻³ m
