Answer:
C. Technician B
Explanation:
Excessive Galvanic activity:
To check for excessive galvanic activity, voltmeter is used to check the coolant. If the voltmeter is giving a reading greater than 0.5 V, there is excessive galvanic activity. Excessive galvanic activity is solved by flushing the coolant fluid from engine and refiling it.
Electrolysis problem:
When the system is not properly ground, the cooling system accepts stray current and the coolant becomes an electrolyte which might eat up the radiator. To test for excessive electrolysis, start the engine and turn on all electrical accessories, if the reading is more than 0.5 V, there is electrolysis problem. Ground wires and connections should be checked at this point to stop stray current.
In our case, the first reading is 0.2 V(engine turned off) which is normal and there is no excessive galvanic activity. This means that Technician A is not correct. The second reading is 0.8 V when the engine and all electrical accessories are turned on. This reading is greater than 0.5 V which means there is an electrolysis problem. This means that Technician B is correct and ground wires and connections should be inspected and repaired.

Answer:
Mutual inductance, 
Explanation:
(a) A toroidal solenoid with mean radius r and cross-sectional area A is wound uniformly with N₁ turns. A second thyroidal solenoid with N₂ turns is wound uniformly on top of the first, so that the two solenoids have the same cross-sectional area and mean radius.
Mutual inductance is given by :
(b) It is given that,
Radius, r = 10.6 cm = 0.106 m
Area of toroid, 
Mutual inductance, 
or
So, the value of mutual inductance of the toroidal solenoid is 
. Hence, this is the required solution.
Answer:
A large area of a forest will likely have higher biodiversity than a smaller area of the same forest.
A half acre of rainforest would likely have greater biodiversity than a full acre of desert.
Explanation:
biodiversity of an ecosystem can be simply explain as the variability that exist in the ecosystem. These are difference that exist between living organism in terms of their habitat, their species and so on. However there exist different relationship between the area of ecosystem and the biodiversity of an ecosystem such that An ecosystem with large area of a forest will likely have higher biodiversity than a smaller area of the same forest.
Another one is that A half acre of rainforest would likely have greater biodiversity than a full acre of desert.
