What is the output voltage from a step up transformer with 25 turns in the primary coil and 75 turns in the secondary coil if th
Greeley [361]

Answer:

360 V

Explanation:

We can use the transformer equation:

\frac{V_p}{N_p}=\frac{V_s}{N_s}

where

V_p is the primary (input) voltage

N_p is the number of turns in the primary coil

V_s is the secondary (output) voltage

N_s is the number of turns in the secondary coil

In this problem,

V_p = 120 V\\N_p = 25\\N_s = 75

Substituting into the equation, we can find the output voltage:

V_s = N_s \frac{V_p}{N_p}=(75)\frac{120}{25}=360 V

A sample of gas has an initial volume of 4.5 L at a pressure of 754 mmHg . Part A If the volume of the gas is increased to 8.5 L
Firdavs [7]

Answer:

The pressure will be of 399.17 mmHg.

Explanation:

p1= 754 mmHg

V1= 4.5 L

p2= ?

V2= 8.5 L

p1*V1 = p2*V2

p2= (p1*V1)/V2

p2= 399.17 mmHg

Sphere A has a charge of +2 x 10 to the power of -6 coulomb and is brought into contact with a similar sphere, B which has a cha
Setler [38]
When sphere A and B are brought in contact and separated, charge on each sphere becomes [2x10^-6 + (-4x10^-6)]/ 2 = -1x10^-6 C.

That is, charge is equally separated and is the average of charges on both spheres. The reason behind equal charge on both spheres after separation is, when they are kept in contact, their potential difference becomes same.
