If Resistors are in series= The equivalent is the sum.
E.g R1 and R2 in series, R = R1 + R2.
If in Parallel, equivalent is Product/sum.
E.g If R1 and R2 in parallel, R = (R1*R2)/(R1+R2)
1.) 60 is parallel with 40 and both are then in series with 20.
60//40 = (60*40)/(60+40) = 2400/100 = 24
Now the 24 is in series with the 20
R = 24 + 20 = 44 ohms.
2.) 80 is in series with 40 and both are then in parallel with 40.
Solving the series, R = 80 + 40 =120.
Parallel: 120//40 = (120*40)/(120+40) = 4800/160 = 30
Equivalent Resistance = 30 ohms.
3.) 100 is in parallel with 100 and both are then in series with the parallel of 50 and 50.
The 1st parallel = (100*100)/(100+100) = 10000/200 = 50
The 2nd parallel = (50*50)/(50+50) = 2500/100 = 25.
Solving the series = 50 + 25 =75 ohms.
Cheers.
Answer:
Explanation:
Distance travelled = 600 - 500 = 100 m
Time taken = 9:03:25 a.m.- 9:03 :05 a.m.
= 20 s
average speed = distance / time taken
= 100 / 20 m /s
= 5 m /s
I need to know what potential engery is can any of you woman help me
(Google Definition) potential energy. The energy an object has because of its position, rather than its motion. An object held in a person's hand has potential energy, which turns to kinetic energy — the energy of motion — when the person lets it go, and it drops to the ground.
(Example of Potential Energy) Potential energy is mechanical or stored energy from an object that comes from factors such as its position relative to others, internal stress, electric charge or its condition rather than motion.
Examples of elastic potential energy include springs, rubber bands, and slingshots. Electric - Electric potential energy is the capacity for doing work based on the object's electric charge. Nuclear - The potential energy of the particles inside an atom.
These are examples from online to get you started
Hope that helped
