Answer:
Parallel, R2, R1, series
Explanation:
From Ohm's law, V=IR hence making current the subject of the formula then
Since R1>R2 eg 4>2 then current for individual connection of R2 will be greater than that for R1 for example, assume V is 8 then if R2 we will have 8/2=4 A but for R1 we shall have 8/4=2 A.
When in parallel, the equivalent resistance will be given by for example here it will be 1/4+1/2=3/4. Still taking V of 8 then I= 8/(3/4)=10.667 A
When in series connection, equivalent resistance is given by adding R1 and R2 hence using the same figures we shall have 4+2=6 hence I=8/6=1.33A
We can conclude that the arrangement of current from greatest will be parallel, R2, R1, series
Answer:
The muscles, joints and bones are adversely affected by immobility. The bones lose calcium as a result of the lack of weight bearing activity and this can lead to disuse osteoporosis, hypercalcemia, and fractures.
Electric field strength near the surface of sphere is given by
Now we have
Q = 1 C
R = 5 cm
now electric field is given by
Part B)
Since charge on the sphere is very large to electric field near its surface is too high. So this is reasonable result near it.
Part c)
As per our assumption the charge is uniformly distributed on the surface and there is no effect of surrounding charge or surrounding electric field.
