Three 9W -3 V bulbs is to be lighted by a suppy of 12 Volt.For this,a wire is to be connected in series with it.Th resistance of the wire should be:A) 1
B) 2
C) 3
D) 4

Answers

9W 3V bulb need current flow
I = P/V = 9/3 = 3A

connected serially, voltage drop on the wire will be = Vsupply - 3(Vbulb) = 12 - 3(3) = 3V.

resistance of the wire ,with I=3 and V=3, = V/I = 3/3 = 1 Ohm.
In order for a 3V bulb to dissipate 9W, the current through it must be 3A.
R = E/I = 3v/3A .  The resistance of such a bulb is 1 ohm.

There are two correct answers to the question, since the question itself
is ambiguous and may be understood in two different ways (at least) ...
series and parallel.

If the three bulbs are in series and the mystery wire will be placed
in series with them, then . . . . .

-- The current everywhere in the series circuit is 3 A .
-- The resistance across the supply is  R = E/I = 12v/3A  =  4 ohms.
-- 3 of the total 4 ohms is in the bulbs.
-- The additional wire must provide the additional 1 ohm .

If the three bulbs are in parallel and the mystery wire will be placed
in series with them, then . . . . .

-- The three bulbs in parallel form an effective resistance of 1/3 ohm.
-- The voltage across the parallel section of the circuit is 3v.
-- The additional wire must drop 9 volts across itself. 
-- The total current through the 3 branches of the parallel section,
    as well as through the additional piece of wire in series with it, is 9 A.
--  The resistance of the wire must be  R = E/I  =  9v/9A = 1 ohm.

Verrry interesting ! 
Whether the bulbs are in series or in parallel,
the same 1-ohm piece of wire does the job.

Avg velocity definition | Problem Average velocity vectors… show how fast something is going at a given instant.
show the average speed of something.
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
are everything you need to determine the displacement of something.

Answers

Answer:

point in the same direction as the change in position.

require knowing the initial and final position, along with the elapsed time.

Explanation:

As we know that average velocity is defined as the ratio of change in position and the time interval of the object

It is given as

v_(avg) = (\Delta x)/(\Delta t)

so we will have

\Delta x = displacement

\Delta t = time interval

the direction is this average velocity is always along the direction of the displacement

so correct answer will be

point in the same direction as the change in position.

require knowing the initial and final position, along with the elapsed time.

A particle moves in a straight line with constant speed of 4 m/s for 2 s, then with 6 m/s for 3 s. The average speed of the particle in the given time interval be v. Find [v].(where, [ ] is step integer function)

Answers

Answer:

Explanation

Total time, T=2+3=5 s

Total distance, D=4×2+6×3=26 m

Thus, average speed=D/T=26/5=5.2

Thus, [x]=5
