The electrical resistance of a wire varies as its length and inversely as the square of the diameter.
R = (k*L)/(d^2)
where k = proportionality constant
Since the two wires have the same material, their proportionality constant is same.
Equating that
(R1*d1^2)/L1 = (R2*d2^2)/L2
Given that R1 = 10 ohms, d1 = 1.2 mm or 0.0012 m, L1 = 18 m, d2 = 1.5 mm or 0.0015 m, L2 = 27 m, and R2 is unknown.
Therefore
[10*(0.0012^2)]/18 = [R2*(0.0015^2)]/27
R2 = 9.6 ohms
35 is greater than
36 is equal to
Answer:
They have the same rate of change.
Step-by-step explanation:
Well the graph of Function B is y = 1 / 3x + 2
So they have the same rate of change, since they have the same slope.
Answer:
Step-by-step explanation:
We are given that velocity vector of a particle
When t=0 then the particle is at the point (0,-1,1).
We have to find the position of particle at time t.
We know that
Velocity =
Therefore,
Integrate on both sides then we get
Substitute the value of point at time t=0 then we get
C=
Substitute the value of C then we get
Therefore, the position of particle at time t
