The light that hits the surface of it is scattered.
Answer:
time of flight of a pulse, and these most often
involve triggering of the measuring oscilloscope
with the signal that generates the sound pulse and
timing the time delay of the pulse picked up by a
conveniently placed microphone45
. Loren Winters
has reported a method similar in principle to the
present one, but which uses a completely different
detection system6

Explanation:
Answer:
The correct answer is option B)
Explanation:
Considering the given question as -
The space shuttle is located exactly half way between the earth and the moon. Which statement is true regarding the gravitational pull on the shuttle? A) The moon pulls more on the shuttle. B) The earth pulls more on the shuttle. C) Both are equal due to equal distances. D) Both are equal due to the mass of the shuttle.
We know that gravitational pull (F) between any two bodies of mass
and
is given by -
F =
where 'r' is the distance between the two bodies.
Let ,
: Mass of the earth
: Mass of the moon
m : Mass of the satellite
: Distance of satellite from earth
: Distance of satellite from moon
Given that
=
Let
=
=r
Force on satellite by the earth is -
= 
Force on satellite by the moon is -
= 
∵ Mass of earth (
) > Mass of moon (
)
∴
> 
∴ The gravitational pull of earth on satellite is more than that of the moon.
Answer:
The amount of charge at the center is -132.7 nC
Solution:
As per the question:
Electric flux from one face of cube, 
Edge, a = 19cm
Since, a cube has six faces, thus total flux from all the 6 faces = 
Also, from Gauss' law:
