Explanation:
part A
series. combination of resistance
R=R1+R2
given R1=25 and R2=15
R=25+15
R=40
partB
parallel combination of resistance
given R1=220 and R2=430
R=1/R1 +1/R2
R=1/220+1/430
R=13/1892
Answer:
Nodes.
Explanation:
Nodes are a point that are on a standing wave that never move.
When all of the objects are lifted to the same height, the object
that has the most mass also has the most potential energy.
If we knew anything about the masses of the objects in this question,
then we could be more specific.
Calculation:
<em>Potential energy = (mass) x (gravity) x (height above the reference level)</em>.
Answer:
The axle is fixed to a frame or a block. The pulley is normally fixed to a support above the load. The load is tied to one end of the rope and the effort is applied at the other end. Such a pulley makes our work easier by simply changing the direction of the force, i.e. a load is lifted up using a downward effort.
