In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance. What is the total resistance?
Sauron [17]

Answer:

17 ohms

Explanation:

Given that,

In a series circuit there are 17 light bulbs, each providing 1 ohm of resistance.

We need to find the total resistance of the circuit.

The equivalent resistance for series combination is given by :

R_{eq}=R_1+R_2+....

For 17 light bulbs, the equivalent resistance is given by :

R_{eq}=R+R+....\text{upto 17 terms}\\\\R_{eq}=17R\\\\=17

Hence, the total resistance is 17 ohms. Hence, the correct option is (d).

8. How much heat is released when 85.0 g of steam condense to liquid water?
sergeinik [125]

Answer:

199920J

Explanation:

Given parameters:

Mass of steam  = 85g

Unknown:

Heat released when the liquid is condensed  = ?

Solution:

The heat released by the substance is given as;

         H  = mL

H is the heat released

m is the mass

L is the latent heat of steam  = 2352J/g

Heat released  = 85 x 2352  = 199920J
