A parallel circuit is shown in the diagram above. In this case the current supplied by the battery splits up, and the amount goi

ng through each resistor depends on the resistance. If the values of the three resistors are: R1 = 82, R2=82, and R3 = 42, the total resistance is found by: 1/R = 1/8+1/8+ 1/4 = 1/2. This gives R = 22. With a 10 V battery, by V = 1 R the total current in the circuit is: I = V/R = 10/2 = 5 A. The individual currents can also be found using I = V/R. The voltage across each resistor is 10 V, so the resistance across R1 : 2.5A 1.25V 2.5V 1.25A​

A double-slit diffraction pattern is formed on a distant screen. If the separation between the slits decreases, what happens to
STALIN [3.7K]

Answer:

The distance between interference fringes increases.

Explanation:

In a double-slit diffraction pattern, the distance of the n-order fringe from the centre of the pattern is

y=\frac{n \lambda D}{d}

where \lambda is the wavelength of the light, D the distance of the screen, and d the separation between the slits.

If we take two adjacent fringes, n and (n+1), their distance is

\Delta y = \frac{(n+1)\lambda D}{d}-\frac{n\lambda D}{d}=\frac{\lambda D}{d}

so, we see that it is inversely proportional to the slit separation, d.

Therefore, if the separation between the slits decreases, the distance between the interference fringes increases.

A coin is placed on a vinyl stereo record that is making 33 1/3 revolutions per minute on a turntable. (a) In what direction is
mamaluj [8]

Answer: a) The acceletarion is directed to the center on the turntable. b) 5 cm; ac= 0.59 m/s^2; 10 cm, ac=1.20 m/s^2; 14 cm, ac=1.66 m/s^2

Explanation: In order to explain this problem we have to consider teh expression of the centripetal accelartion for a circular movement, which is given by:

ac=ω^2*r where ω and r are the angular speed and teh radios of the circular movement.

w=2*π*f

We know that the turntable is set to 33  1/3 rev/m so

the frequency 33.33/60=0.55 Hz

then w=2*π*0.55=3.45 rad/s

Finally the centripetal acceleration at differents radii results equal:

r= 0.05 m  ac=3.45^2*0.05=0.50 m/s^2

r=0.1  ac=3.45^2*0.1=1.20 m/s^2

r=0.14 ac=3.45^2*0.14=1.66 m/s^2

Korolek [52]

Answer:

2C  charge will flow from ground and cloud

Explanation:

We have given rate rate of flow of charge \frac{dq}{dt}=20000C/sec

Time is given as t=100\mu sec=100\times 10^{-6}=10^{-4}sec

WE have to find the how much charge flows between the ground and cloud in this time

So the charge flow is given by \frac{dq}{dt}\times t=20000C/sec\times 10^{-4}=2C

So 2C  charge will flow from ground and cloud
