Explanation:
A calorimeter has a heat capacity of 1265 J/°C
Heat capacity of calorimeter = 1265 J/°C
A reaction causes the temperature of the calorimeter to change from 22.34°C to 25.12°C
Change in temperature = 25.12 - 22.34 = 2.78°C
Heat released = Heat capacity of calorimeter x Change in temperature
Heat released = 1265 x 2.78 = 3516.7 J
Heat released in this process is 3516.7 J
Answer:
heat released is
It is given that, heat capacity of calorimeter is, H =
Also , initial temperature of calorimeter,
final temperature of calorimeter,
We know , Heat will release when it is positive.
So, heat released , Heat =.
Since it is positive. Therefore, heat released is
40 V
I will assume that the resistors are
100 and 3900 and 1000 OHMS <=====(NOT W)
In series , the resistances add together 100 + 3900 + 1000 = 5000 ohms total
V = IR
I = V / R so the total current will be 200 v / 5000 ohms = .04 amps
this is the current through all of the resistors
so for the 1000 ohm resistor V = IR .04 (1000) = 40 V
I feel it would be D. 120.00 I'm really not sure
Power lines
Generators induce that current that runs the turbines
Turbines also induce currents from water waves that is transmitted.
Transformers change A.C to D.C or vice versa.
12000 miles per hour
If skid Marx went from zero to 10 miles in 3 seconds the his speed would have been 12000 miles per hour.
