Given R2’s resistance and voltage we can find the current through it of 1.5 amps. Due to Kirchhoff’s junction rule the current going in must match the current going out so the current through them all is 1.5 amps. Using this we can find the voltage through R1 of 15v. Then we subtract V1+V2 from 120 to find that R3 has a voltage of 60v. Next we find that R3 has a resistance of 40 ohms
The final answer is 51.6 microC which is answer choice b:
There is no (gap) in time between the action and the reaction

#6). The tangent of an angle in a right triangle is
(opposite side) / (adjacent side) .
The side opposite the marked angle is 4cm.
The side adjacent to the marked angle is 12cm.
The tangent of the marked angle is (4cm / 12cm) = 1/3 .
The marked angle is the angle whose tangent is 1/3 .
You can find that online, or with your calculator, slide rule, Curta, or book.
#7). The cosine of an angle in a right triangle is
(adjacent side) / (hypotenuse) .
The side adjacent to the marked angle is 15m.
The hypotenuse is 19m.
The cosine of the marked angle is (15m / 19m) = about 0.78947...
The marked angle is the angle whose cosine is 0.78947... .
You can find that online, or with your calculator, slide rule, Curta, or book.
Answer:
Temperature is simply a measure of energy present. The heating and cooling of the atmosphere cause currents as cold air moves towards warmer air.
Explanation:
The most basic thing to understand is that warm air wants to rise while cold air wants to sink. Hot air contains fewer molecules per cubic meter while cold air contains more, hence the warm air will rise up over colder air. The most common example of this is the existence of a hot or cold front. These fronts are simply boundaries between hot and cold air.
