Answer:
a) 
b) 
Explanation:
a)
In order to solve this problem, we need to start by remembering how the acceleration is related to the velocity of a particle. We have the following relation:
in other words, the acceleration is defined to be the derivative of the velocity function with respect to time. So let's take our speed function:
u=20-2x
if we take its derivative we get:
du=-2dx
this is the same as writting:
we also know that velocity is defined to be:
so we get that:
a=-2u
when substituting we get that:
a=-2(20-2x)
when expanding we get:
a=-40+4x
and now we can use this equation to find our acceleration at x=3, so:
a=-40+4(3)
a=-40+12
b)
the same applies to this problem with the difference that this will be the rate of change of the temperature per m. So we proceed and take the derivative of the temperature function:
T=200-5x
so the rate of change is 
Answer:
FALSE.
Explanation:
the correct answer is FALSE.
Projection is the process of representing the 3 D object on the flat surface.
there are four ways of representing the projection
1) First angle projection
2) second angle projection
3) third angle projection
4) fourth angle projection.
Generally, people prefer First and third angle projection because there is no overlapping of the projection take place.
In USA people uses the third angle of projection.
Answer:
36V, 100A-hr
Explanation:
Since the batteries are connected in series;
i. the output voltage will be the sum of the individual voltages
ii. the current rating (A-hr) will be the same as their individual current rating (A-hr). And this is because the same current flows through the batteries.
From i,
The output voltage, V, is given by the sum of the voltages of the three batteries;
V = 12V + 12V + 12V
V = 36V
From ii,
The A-hr capacity of the connection is the same as that of the individual batteries;
100 A-hr
Therefore, the output voltage and A-hr capacity of this connection is:
36V, 100A-hr
