Answer:
A chain
Explanation:
A series circuit is a circuit, where the resistors are arranged in a chain. They are aligned like this so the current only has one path to take. The current quantity is the same through each resistor.
If you ever have trouble remembering this you can think of a movie series which goes on and on and on. And remembering a parallel circuit is simpler because everything in the circuit will be parallel!
A :-) for this question , we should apply
a = v - u by t
Given - u = -2 m/s
v = -10 m/s
t = 16 sec
Solution -
a = v - u by t
a = -10 - -2 by 16
a = -12 by 16
( cut 12 and 16 because 2 x 6 = 12 and
2 x 8 = 16 )
( cut 6 and 8 because 2 x 3 = 6 and
2 x 4 = 8 )
a = 3 by 4
a = 0.75 m/s^2
.:. The acceleration is 0.75 m/s^2.
Answer:
Part(a): The value of the spring constant is 
.
Part(b): The work done by the variable force that stretches the collagen is 
.
Explanation:
Part(a):
If '
' be the force constant and if due the application of a force '
' on the collagen '
' be it's increase in length, then from Hook's law
Also, Young's modulus of a material is given by
where '
' is the area of the material and '
' is the length.
Comparing equation (
) and (
) we can write
Here, we have to consider only the circular surface of the collagen as force is applied only perpendicular to this surface.
Substituting the given values in equation (
), we have
Part(b):
We know the amount of work done (
) on the collagen is stored as a potential energy (
) within it. Now, the amount of work done by the variable force that stretches the collagen can be written as
Substituting all the values, we can write
The total resistance of an electric circuit with resistors widener series in the sum of the individual resistances:
Each resistor in a series circuit has a same amount of current flowing through it.
Each resistor in a parallel circuit has the same for voltage of the source applied to it.
When was this is are connected in parallel, the supply current is equal to the sum of the current through each resistor. In other words the currents in the branches of a parallel circuit add up to the supply current. When resistors are connected in parallel they have the same potential differences across them.
