Answer:
= 19 Ω, I = 0.105 A, V1 = 1.05 V and V2 = 0.95 V
Explanation:
The correct way to solve this type of problem is to find the current or voltage values for the equivalent resistance and from here find the other values.
For a series circuit the equivalent resistance is the sum of the resistance
= R1 + R2
= 10 +9
= 19 Ω
Let's use the equation for the voltage
V = I
I = V /
I = 2/19
I = 0.105 A
In a series circuit the current is constant, so let's use the voltage equation for each resistor
V1 = I R1
V1 = 0.105 10
V1 = 1.05 V
V2 = 0.105 9
V2 = 0.95 V
Note that the sum of this voltage is the total voltage applied.
The center of the sun gets up to at least 27 million degrees Fahrenheit.
Explanation:
Method of Aristarchus. wait patiently until the moon is half full literally exactly. Then the Earth, the Moon, and the Sun form a right triangle with moon being at right angle Now we need to measure the angle between the Moon and the Sun, and with the distance of the Moon (previously found by triangulation) obtain the length of the Sun as the distance of the Moon distanced by the angle cosine. The ambiguities in that "precisely" make this a weak method. Once the correct value is nearly 400 times, Aristarchus himself got the Sun 30 times as far away as the Moon.

Hi
<u>Knwons</u>
Mass , Work and Force
a) Here we are going to use , so
a) Here we are going to use , so or approx.
A seems wrong because with 20 N the can should go more than .5 m so I would say the awnser is B
Hope I Helped :)
