When light strikes a black surface, it is reflected by the surface and

nothing is absorbed    This would be False because black absorbs the light not reflect

Mirrors are used in telescopes because they have the ability to reflect

True? Telescopes designed with mirrors avoid the problems of refracting telescopes. Because the light is reflected from the front surface only, flaws and bubbles within the glass do not affect the path of the light

Transmission in the passing of light through some materials​

False? Some materials allow much of the light that falls on them to be transmitted through the material without being reflected. Materials that allow the transmission of light waves through them are called optically transparent. ... Materials which do not allow the transmission of any light wave frequencies are called opaque.

A certain sound is recorded by a microphone. The same microphone then detects a second sound, which is identical to the first on
katrin [286]

Answer:

Loudness of the second sound is more than the first one.

Explanation:

There are two sounds, the second sound is identical to first but the loudness of second is more than the first one.

As the frequency is same so the itch is same for both the sounds.

As the loudness depends on the amplitude of the sound so the loudness of the second sound is more than the first sound.

Two positive charges ( 8.0 mC and 2.0 mC) are separated by 300 m. A third charge is placed at distance r from the 8.0 mC charge
WINSTONCH [101]

Answer:

r=200m

Explanation:

From the question we are told that:

Charges:

Q_1=8.0mC

Q_2=2.0mC

Q_3=8.mC

Distance d=300m

Generally the equation for Force is mathematically given by

F=\frac{kq_1q_2}{r^2}

Therefore

F_{32}=F_{31}

\frac{q_2}{(300-r)^2}=\frac{q_1}{r^2}

\frac{2*10^{-3}}{(300-r)^2}=\frac{8*10^{-3}}{r^2}

r=2(300-r)

r=200m
