Answer:
Explanation:
The resistance column is correct.
I1 = I2 = I3 = I4 = 2 Amps
So all the currents are the same.
R = 110
I = 2 amps
V = ?
Vt = I * R
Vt = 2 * 110
Vt = 220
=============
V1 = 20 * 2 = 40 volts. That's 40 volts dropped from the right side of R1 to the left side.
V2 = 60 * 2 = 120 volts across the 60 ohm resistor
V3 = 30 * 2 = 60
Total voltage = 40 + 120 + 60
Total voltage = 220 which is just what it should be.
==========================
Power
P1 = V1 * I
P1 = 40 * 2
P1 = 80 watts
P2 = 120*2
P2 = 240
P3 = 60 * 2
P3 = 120
Total Power = 80 + 240 + 120
Total Power = 440

Answer:
a) The module's acceleration in a vertical takeoff from the Moon will be 
b) Then we can say that a thrust of
won't be able to lift off the module from the Earth because it's smaller than the module's weight (
).
Explanation:
a) During a vertical takeoff, the sum of the forces in the vertical axis will be equal to mass times the module's acceleration. In this this case, the thrust of the module's engines and the total module's weight are the only vertical forces. (In the Moon, the module's weight will be equal to its mass times the Moon's gravity acceleration)

Where:
thrust 
module's mass 
moon's gravity acceleration 
module's acceleration during takeoff
Then, we can find the acceleration like this:


The module's acceleration in a vertical takeoff from the Moon will be 
b) To takeoff, the module's engines must generate a thrust bigger than the module's weight, which will be its mass times the Earth's gravity acceleration.

Then we can say that a thrust of
won't be able to lift off the module from the Earth because it's smaller than the module's weight (
).
The periodic table is arranged in a way that trends are present in columns and rows. Elements belonging to the same column belongs to the same family which means they have the same properties. Elements belonging to the same row have the same number of electron shells. Example of elements with the same chemical properties are Na, Li, and K all belonging to the same group.
