<Solve using the formula which is:
Mass=Density×Volume

3)
(Length × Width × Height)
(Answer=7.5)
Using Ohm's Law, we can derived from this the value of resistance. If I=V/R, therefore, R = V/I
Substituting the values to the given,
P = Power = ?
R = Resistance = ?
V = Voltage = 2.5 V
I = Current = 750 mA
R = V/I = 2.5/ (750 x 10^-3)
R = 3.33 ohms
Calculating the power, we have P = IV
P = (750 x 10^-3)(2.5)
P = 1.875 W
The power consumption is the power consumed multiply by the number of hours. In here, we have;
1.875W x 4 hours = 7.5 watt-hours
1. 2700 joules
2. im not sure about this one give me a sec
I would say C. if im wrong, im sorry. but if im right your welcome. i didnt guess tho.
