Answer:van der Waals forces
Explanation:van der Waals forces are weak bond that occurs between oppositely charged molecules like in the case of a magnet
Answer:
B) R1 = 6 V and R2 = 6V
Explanation:
In series, both resistors will carry the same current.
that current will be I = V/R = 12 / (10 + 10) = 0.6 A
The voltage drop across each resistor is V = IR = 0.6(10) = 6 V
Electromagnetic and Gravitational forces are most alike because their range is not limited.
im not sure about most of this but ill try to help
so there are three formulas you need to know first: the formula for rate distance and time.
to find distance:
distance = rate * time
to find time:
time = distance / rate
and to find rate (which is what we need)
rate = distance / time
now we just use our formula and plug in the numbers
rate = distance * time
rate = 160 / 2 = 80
so our rate is 80. thats all i know i have no idea about the rest but i always use these messurments. im sure you can google most of it to get other formulas and calculators though. sorry i couldnt help much! good luck :D
Answer:
R2 = 10.31Ω
Explanation:
For two resistors in parallel you have that the equivalent resistance is:
(1)
R1 = 13 Ω
R2 = ?
The equivalent resistance of the circuit can also be calculated by using the Ohm's law:
(2)
V: emf source voltage = 23 V
I: current = 4 A
You calculate the Req by using the equation (2):
Now, you can calculate the unknown resistor R2 by using the equation (1):
hence, the resistance of the unknown resistor is 10.31Ω
