C. a lot of inertia.............................. :-)
Explanation:
An object's weight depends on the pull of the gravitating object but the object'<u>s mass is independent of the gravity. </u>
The factors which are affected will be based on the distance or range between the charged objects A and B
<u>Explanation:</u>
<u>Definition:</u>
- The force, F among the two-point size charges A and B are divided by a range r is given by Coulomb formula.
F=9x10^9 AB/r²
<u>Factors:</u>
- If the range among them is doubled the force will be decreased to 1/4 of the initial value. And if the range is split, the force will be four times.
- If the range among them is tripled, the force will be decreased to 1/9 of the initial value. If the range is decreased to one-third of the new value, the force will rise to Nine times the initial value.
Answer:
1234285.7 m or 1234.3 km
Explanation:
Let the distance be
, the time taken by P waves be
and the time taken by the S waves be
.


For the P waves,


For the S waves,


Equating the
,

Divide both sides of the equation by 500 to reduce the terms.

Since S waves arrive 2 minutes (= 120 seconds) after P waves,


Substitute this in the equation of the distance.




Substitute this in the equation for
involving
.
