Answer:
I think the answer might be the first one
Answer:
Another very important reason why people prefer to live in valleys instead of plateaus is because of available sources of water. This conducive nature of valleys in turn accommodate factors like economic growth,social and cultural, which in turn attract more people, hence making these areas densely populated.
Answer: The angle of inclination is nearly 30°
Explanation:
For a body on an inclined plane, the coefficient of friction between the body and the plane is equal to the ratio of the moving force applied to the body to the frictional force acting on the body.
If uK coefficient of friction;
Fm is the moving force
R is the normal reaction on the body
Mathematically uK = Fm/R
Fm = WSin(theta)
R = Wcos(theta)
uK = Wsin(theta)/Wcos(theta)
uK = tan(theta)
theta = arctan(uK)
If uK is 0.58
theta = arctan0.58
theta = 30°
The angle of the inclined will be 30°
Series circuits - cpt connected so that the same current passes through each of them.
Disconnection/break in series circuit and current doesn't flow.
Current same
The total potential difference across all of the components. (the sum of the pds across the individual series elements).
The diagram in the enclosure seems to show resistors in parallel. Which is a bit confusing ...
