<u>Answer:</u>
1A, 2E, 3C, 4F, 5B, 6D
<u>Explanation:</u>
Tilt meter is a an equipment used to measure very small changes from vertical level. So it is a correct match for blank space in statement A.
Richter Scale is a scale of measurement of earthquake strength, So it is a correct match for blank space in statement E.
Mercalli Intensity Scale measures effect of an earthquake, like damage caused.So it is a correct match for blank space in statement C.
Seismograph is earthquake wave measuring instrument. So it is a correct match for blank space in statement F.
Correlation Spectrometer (C.O.S.P.E.C.) is used to measure sulfur dioxide content in smoke. So it is a correct match for blank space in statement B.
Moment Magnitude Scale is an earthquake measuring scale for great earthquakes. So it is a correct match for blank space in statement D.
Answer: The mountains that we observe on the moon, from earth are those rims forming the lunar mountains and mountain ranges. It has formed due to the asteroidal impact on the surface of the moon, billions of years back, resulting in the depressions and the highland areas. Due to this impact, a huge amount of heat energy generated that eroded and melted much of the materials from the moon's surface.
Answer:
A and C
Explanation:
Kinetic energy of a body is given by the expression,
, where v is the velocity and m is the mass of body.
In case of a simple pendulum the maximum velocity is at it's stationary position.
So maximum velocity i at position C, which means maximum kinetic energy is at position A.
The velocity of pendulum reduces as the angle between vertical stationary and current position increases.
So, velocity at E and A are the minimum, so at A and E the kinetic energy value is minimum.
Now examining the options given, we will understand the kinetic energy increase is maximum in case of A and C.
Answer:
The force between two charges when they are separated by distance 12 cm is
Explanation:
Here lets us consider two charges
and
.
Let
be the force between them when they are separated by distance 6 cm
be the force between them when distance between them = 12 cm
=20 N ..................1
...................2
Dividing both equations , we get

.
Here we need not to know the values of charges , since they get cancelled while dividing.
