Answer:
Explanation:
When a substance is supplied with a certain amount of heat energy, the temperature of the substance increases according to the equation
where
m is the mass of the substance
Q is the amount of energy supplied
C is the specific heat of the substance
is the temperature change
In this problem:
Q = 758 J is the energy supplied
m = 0.750 kg is the mass of the sample
is the specific heat of copper
Re-arranging the equation, we can find the increase in temperature:
Answer: a) 0.11 Amp b) 0.000429 Joules c) 0.000514 watt
Explanation:
a)current
I=V/r I=6.0/550 =1.1*10^-2 A
b) energy
E= 1.1*10^-2 x (6.0) x 0.00065s(<-- remember to convert ms to seconds) = 0.000429J
C) Average power
P = (0.000429 x 72) / 60
P = 0.000514 W
Answer:
b
Explanation:
this is because inoder. for combustion or burning to take place oxygen must be available
