A refrigerator receives 240 V of electricity. If it uses 32 A of current, what is the resistance of the refrigerator?
Leokris [45]

\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Ohms Law,

According to the Ohms law,

V = I*R, where, V = Voltage, I = Current, R = resistance,

so here given as, V = 240 V, I = 32 A,

so we get as, R = 240/32

R = 7.5 ohms,

===> The resistant R is ==> 7.5 ohms.

How much heat Q2Q2 is transferred to the skin by 25.0 gg of steam onto the skin? The heat of vaporization for steam is L=2.256×1
astraxan [27]

Answer:

56400Joules

Explanation:

The quantity of heat required is expressed as;

Q = mL

m is the mass = 25g = 0.025kg

L is the latent heat of vaporization for steam = 2.256×10^6J/kg

Substitute into the formula as shown;

Q = 0.025×2.256×10^6

Q = 56400Joules

Hence the quantity of hear required is 56400Joules
