Answer:
A=50mΩ
B≅50mΩ
Explanation:
A) To answer this question we have to use the Current Divider Rule. that rule says:
(1)
Itotal represents the new maximun current, 50mA, Ix is the current going through the 100 ohms resistor, and Req. is the equivalent resitor.
We now have a set of two resistor in parallel, so:
(2)
where R1 is the resitor we have to calculate, and R2 is the 100 ohms resistor (25 uA).
substituting and rearranging (2)
(3)
Now substituting (3) in (1).
solving this, The value of R1 is: 50mΩ
This value of R1 will guaranty that the ammeter full reflection willl be at 50mA.
Given that R2 (100ohm) it too much bigger than 50mΩ, the equivalent resistor will tend to 50mΩ
If you substitude this values on (2) Req. will be 49.97 mΩ.

Answer:
Explanation:
First, define 
( electromotive force )-is the unit electric charge imparted by an energy source. In this case the generator.
The peak emf is:
=
Substituting 
and the value for peaf 
gives:
Total length=

=
Hence, wire's length is 171.43m
Answer:
The force of impact, F = 17682.18 N
Explanation:
Given,
The initial velocity of the truck and associated velocity of RV, u = 2 m/s
The height of the cliff, h = 280 ft
= 85.344 m
The mass of the RV, m = 1800 Kg
The total energy of the RV at height, 'h' with velocity, 'v', E = P.E + K.E
P.E = mgh J
= 1800 x 9.8 x 85.344
= 1505468.16 J
K.E = mv²/2
= 1800 x 2² / 2
=3600 J
Therefore total energy, E = 1509068.16 J
This is equal to the kinetic energy of RV at the impact.
The force of impact,
F = E/h
= 1509068.16 J / 85.344 m
= 17682.18 N
Hence, the force of impact of RV is, F = 17682.18 N
