An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object's distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.
Answer:
new energy of the capacitor is half that of initial energy
Explanation:
As we know that the energy stored in the capacitor is given as

here we know that capacitance of parallel plate capacitor is given as

V = voltage of battery
so now we have capacitor remains connected to the same battery and the separation between the plates is doubled
so we have

so now the energy stored between the plates is

so new energy of the capacitor is half
Answer:
t=L/
Explanation:
<u>solution:</u>
Let E be an observer, and B a second observer traveling with velocity
as measured by E. If E measures the velocity of an object A as
then B will measure A velocity as
=
-
Applied here,
the walkway (W) and the man (M) are moving relative to Earth (E}, the velocity of the man relative to the moving walkway is
=
-
,

The time required for the woman, traveling at constant speed
relative to the ground, to travel distance L relative to the ground is
:
t=L/
Answer:
do you mean how? if so
Explanation:people used newspapersand still kinda do back then they had posters up as they still do and newspapers
