Question

Q2. The resistor R₁,R2 and R3 have the values of 30ohm,20ohm and 60 ohm respectively, which have been connected in a parallel connection to a battery of 12V.​

Answer 1

GIVEN:

V=12V

R1=30 ohms

r2=20 ohms

r3=60 ohms

(connected in parrallel)

i am supposing that you have asked for total resistance i.e. R in this question

$\frac{1}{r} = \frac{1}{r1} + \frac{1}{r2} + \frac{1}{r3}$

$\frac{1}{r} = \frac{1}{30} + \frac{1}{20} + \frac{1}{60}$

$\frac{1}{r} = 0.1ohms$

$r = 10 \: ohms$

Answer 2

Answer:

Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. ... Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.
