Answer:
15"
Explanation:
Let x be the length of the longer part, then the length of the shorter part is 3x/5, or also x - 6
therefore we have the following equation:
3x/5 = x - 6
We can multiply both sides by 5
3x = 5x - 6*5
2x = 30
x = 30/2 = 15"
So the length of the longer part is 15"
Answer:
Repulsion
Explanation, due to this repulsion with the proton and the electron, each electron experiences a nuclear charge that is somewhat less than the actual nuclear charge.
For item#1 , see attached picture, there is a voltage source, a resistor and wire (where current flow).
For item#2, we use the formula V=IR where "V" is for the voltage, "I" is for the current and "R" for the resistance
Solving for I:
I = v/r
I = 45volts/15k ohms
I=3 mA
For item#3, power is P=VI
p = 45volts * 3ma
P = 0.135 Watts
The answer is C because carbon dioxide is trapped in a thick atmosphere.
