Although we can divide the history of the universe into many distinct "eras," sometimes it’s useful just to have a broad perspective on what events occurred in the very early universe and what events occurred later. listed following are events that occurred either before or after the first five minutes in the history of the universe. match these events to the appropriate time period.
when the compass placed near the working of electric wire, the compass needle will be redirected towards the magnetic field created by wire.
the electric wire cause the magnetic field just like a magnet causes magnetic field.
the electric currents always produces their magnetic fields. when we put the compass near the electric wire the current passes through it, and the needle of the compass will not move in north or south, instead, the needle will be pointed in the direction of magnetic field created by the wire.
answer : v = 14.28 m/s
it is given that,
mass of squirrel,
terminal velocity is given by :
where, is density of fluid which is falling and it is given by
a is the surface area of squirrel.
c is the drag coefficient.
the surface area facing the fluid is given by :
so, terminal velocity is :
so, the terminal velocity of squirrel is 14.28 m/s.
