Answer:
C
Explanation:
Rt= total resistance
we know that 1/Rt=1/R1+1/R2(from ohm's law)
Since, Rt=4 and R1=R2
we will get,
1/4=2/R2
R2=8
when in series Rt=R1+R2,
So, Rt=8+8=16 ohm's
The answer is diffraction or interference
Inertia is the resistance of any physical object to any change in its state of motion. inertia exists due to the mass of the object
Answer:
a = 0.77 m/s^2
Explanation:
The centripetal acceleration is given as

The velocity of the car can be calculated using the circumference of the track and the period of the car.

So, the acceleration is
