They get easier once you keep doing them, It took me a little while to learn.
Do you have a exact question? I can help you
Answer:
The resistance is decreasing at a rate of 0.36 ohms/minute.
Step-by-step explanation:
The mathematical form of the Ohm's law is given by :
V = IR ...(1)
Where V is voltage, I is current and R is resistance
Given,
I = 5 A
R = 6 ohms
dI/dt = 0.3 A/min
Differentiate equation (1) wrt t:

When V is constant, dV/dt = 0

So, the resistance is decreasing at a rate of 0.36 ohms/minute.
The answer will be total green plus total red divided by all existing marbles:
(1010 + 4040) / (1010 + 4040 + 5050) = 5050 / 10100 = 1/2 = 0.5
Answer: 0.5
Step-by-step explanation:
in 2nd... one you also have to find a x and a y....if you want a deep explantion...comment me...and if tried to build two equation and use the method i taught u...let me know the answer.i will let you know whether you are right ot not
Answer:
y=(20M+30S) kwh
Step-by-step explanation:
Since each windmill generates M kwh then for ywo windmills, each year they will generate 2 M kilowatt hours
For solar panels, since each generates S kilowatts annually then for 3 of them, the power will be 3 S
Total production per year will be 2M+3S
In n years, the energy will be y(n)=(2M+3S)n
When n is 10 years then
y(10)=(2M+3S)10=20M+30S
Therefore, y=(20M+30S)kwh
