You should back-up your computer every few weeks (or as often as needed).
As soon as you suspect that your computer (or any other backup-able device) is too slow or "glitch-y" you should back-up your device before you lose any important files or data.
PREVENTING MALFUNCTION:
→ Always set your computer on a hard & flat surface.
→ Avoid downloading programs from unknown or non-trusted sources.
→ Avoid using your computer in a hot area.
→ Consider installing a virus/malware protection software on your computer.
Answer:
Ex(P) = -3.602 x 10^6 N/C
Explanation:
- q2 = 2.6 μC = the net charge on the conducting shell
- inner radius of conducting shell = a = 2.2 cm =0.022m
- outer radius of conducting shell = b = 4.5 cm = 0.045m
1) To get Ex(P), the value of the x-component of the electric field at point P, located a distance 8.8 cm along the x-axis from q1 ;
Ex(P) = k(q1+q2)/r^2
= 9 x 10^9 (-5.7 + 2.6) x 10^-6 /0.088^2
Ex(P) = -27.9 x 10^3/ 0.007744
Ex(P) = -3.602 x 10^6 N/C
Answer:
D. two positively charged objects
Actually, two of the statements can be argued to be true:
1)Changing several different factors in an experiment takes too many controls.
This means that for every factor that is changed you need a control which has all the other factors stable - but with many factors, this might be undoable.
2) - and this is the best answer:
When only one factor is changed, you can be more certain that it caused the results.
If this factor is the only thing that changes, you can safely assume that it caused the results!
Not the answer but the answer will nit be B. hope yall find the answer
