Answer:
current in water = 0.924 A
Explanation:
Let the current in each row be i.
Thus, current in water is contributed by each row and total current in water becomes 140i.
We are given;
emf of each electroplaque = 0.15 V
Number of electroplaques = 5000
internal resistance = 0.25 Ω
resistance = 800Ω
Applying Kirchoff's Voltage Law to row and water, we have;
5000E − (5000r)i − 800(140i) = 0
Rearranging;
5000E = (5000r)i + 800(140i)
Plugging in the relevant values;
5000 x 0.15 = i((5000 x 0.25) + 112,000)
750 = 113,250i
i = 750/113,250
i = 0.0066 A
Recall earlier, the current in water is 140i.
Thus, current in water = 140 x 0.0066
= 0.924
Answer:
Option A
Explanation:
The Equation represents the displacement of the object which is represented by x
so, 
means when time is zero so we replace t with zero in the equation,
now for v which is velocity we need to differentiate the function as the formula for velocity is rate of change of displacement over time so we derivate the equation once and get,
now for 
we insert t = 0 and get
now for a which is acceleration the formula of acceleration is rate of change of velocity over time, so we differentiate the the equation of v(velocity) once or the equation of x(displacement) twice so now we get,
so Option A is your answer.
Remember derivative of a constant is always zero because a constant value has no rate of change has its a constant hence the derivative is 0
If you're referring to the different colors that usually occur at the tip of missles, rockets and some other aircraft, it either a) signifies the end of a particular plate of metal, fabricated specifically to be for the nose. Sometimes these can even be a different alloy or metal all together. or b) this shows where the curved surface begins, so in the case of damage or imperfections due to wear, they can be repaired and measured more easily. The shape of the nose is extremely important for smooth flight, and a dent or bump formed on it can make the aircraft unstable. If you can measure from where the curve starts by the difference in color, it makes repairing or re-fabricating the part much easier. Many of these curves aren't as simple as they appear.
