Answer:

When photons - rays of light - coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image.... If a smooth surface absorbs the photons, they can't bounce back and there will be no reflection.

The A string of a violin is a little too tightly stretched. Beats at 4.00 per second are heard when the string is sounded togeth

Basile [38]

Answer:

$T=2.5*10^{-3}s$

Explanation:

From the question we are told that:

Beat frequency $F_b=4$

Frequency $F=400Hz$

Generally the equation for Frequency of the violin is mathematically given by

$f_v=F_b+F$

$f_v=4+400Hz$

$f_v=404Hz$

Therefore the period of the violin string oscillations is

$T=\frac{1}{f_v}$

$T=\frac{1}{404}$

$T=2.5*10^{-3}s$

4. A disobedient student dropped his Physics textbook (mass 0.1kg) from the window (15m above the ground). How fast was it going

vaieri [72.5K]

Answer:

v= 17.15 m/s

Explanation:

mass of the book=0.1 Kg

height above ground, h= 15 m

Using conservation of energy

Potential energy is converted into kinetic energy

$mgh = \frac{1}{2}mv^2$

$v=\sqrt{2gh}$

$v=\sqrt{2\times 9.8\times 15}$

$v=\sqrt{294}$

v= 17.15 m/s

Hence, the book will hit the ground at the speed of 17.15 m/s.
