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
The appropriate hypothesis test for this question is the two proportions test. As the name implies, it is often used to compare existing percentages between two groups. The raw data behind the percentages must be available as the sample size becomes crucially important in determining the test statistics.
The test statistic of the two-proportion test is the Z value. When the sample becomes very large, the Z value is governed under a normal function and is commonly known as the standardized Z value
Answer:
<h2>50
°</h2>
Explanation:
Angle of rotation of the flat polished surface = 15°
angle of incidence i = 20°
Since the polished surface is turned at an angle of 15°, the angle of reflection
r = 2 (Note that the angle of rotation only have effect of the angle of reflection)
r = 2*15 = 30°
The angle between the reflected ray and the incident ray will be equal to the sum of the angle of incidence and the angle of reflection i.e i+r
The angle between the reflected ray and the incident ray = 20°+ 30° = 50°
Answer:
All the hairs on the child's head must gain the same type of charge. Like charges repel so the strands of hair experience a force that pushes them away from each other.

The orbiting spacecraft are put in the atmosphere to gain information about the weather conditions, for satellite communications, for measuring changes in the atmosphere. These crafts are put in the outer atmosphere, where the atmosphere is very thin and the craft can stay its specified orbit.
