Depends on what type of mirror that is. I am going to assume this is a plain mirror (from the phrase), which means the height and width of the object and image is exactly the same.
It is important to work with a partner pay attention to your partner always ask if he needs help never take your eye off of him because in a second he could let go of that bench press because its too heavy and he could seriously be injured.
Cp shows the amount of energy needed to raise temperature by one degree for one gram of water.
Formula for calculating cp is:
Final temperature is 26.73°C.
Answer:
Explanation:
From the information given,
V = 4 volts
A = 2 amps
a)
In the first instance, one light on the sting goes out and the whole string of lights no longer turns on. This means that the circuit is a series circuit.
b) Total voltage = 4 x 100 = 400 V
The current passing through each bulb is the same. Thus
Total Current = 2 Amps
Recall, V = IR
R = V/I
Thus,
Resistance = 400/2
Resistance = 200 ohms
c) In this case, one light goes out on the string all other lights still turn on. This means that the circuit is a parallel circuit
d)
The voltage is the same
Total voltage = 4 volts
Total current = 2 x 100 = 200 amps
Total resistance = 4/200
Total resistance = 0.02 ohms
