0.74in
Explanation:
Given parameters:
length range of adult mosquito = 3.0 - 6.0mm
Smallest mosquito = 2.5mm
Largest mosquito = 19mm
Average mass range = 3.0 - 5.0mg
Unknown:
Length of largest known mosquito in inches = ?
Solution;
The length is the longest dimension. It is how long a body is.
The problem here is converting from mm to inches;
The length of the longest mosquito which is the largest is 19mm
19mm to inches;
1mm = 0.039inches
19mm = 19mm x
= 0.74in

Answer:
A. Generator
Explanation:
An alternator which is also called a generator basically converts mechanical energy into electric energy.
An alternator is used in a vehicle to charge the battery. It supplies electric power to the automobile.It is attached to the engine and is driven by a belt system . When the alternator does not charge the battery, it can be understood that it is not working as it no longer recharges the battery, though the engine of the automobile runs.
The 4ohm resistor is not parallel to any devices, so the current through it is the same as the total current through the circuit.
Apply I = V/R
I = total current, V = battery voltage, R = total resistance
Calculate the total resistance R of the circuit first.
R will be the sum of the 4ohm resistor and the resistance of the 5&9ohm parallel resistors. To find the resistance of the pair, you apply the “sum of inverses” rule:
R = 1/(1/5 + 1/9) = 3.21ohm
Now add the 4ohm resistor:
R = 3.21 + 4 = 7.21ohm
Now let’s calculate I = V/R:
Given values:
V = 6.0V
R = 7.21ohm
Plug in and solve for I:
I = 6.0/7.21
I = 0.83A
