Which statement about average stream velocity is trueVelocity is
Which statement about average stream velocity is true? 
Velocity is higher in the upper reaches where gradients are steeper. 
Velocity is constant along the rivera. 
Velocity is higher in the upper reaches where gradients are steeper.b. 
Velocity is constant along the river 
 
Solution 
 
option c is the right answer because the velocity decreases downstream as the gradient is less the 
slope decrease and hence causes the loss in velocity

Use the shell method to find the volume of the solid generated by revolving the plane region 
about the given line. 
 
 y=x^2, y=4x-x^2, about the x=4 
 
Solution 
 when you draw the curves and the axis of rotation, you'll notice there are two 
regions being rotated: one from x = 0 to x = 2 (from x^2 = 4x - x^2), and from x = 2 to x = 4 (the 
axis of rotation). at any point x, take an infinitesimal shell of thickness dx parallel to the axis of 
rotation. the height of t...

Calculate how much glucose (C6H12O6) you would need to make a 0.5 Li
Calculate how much glucose (C6H12O6) you would need to make a 0.5 Liter solution which is 
0.3 molar. ? 
 
Solution 
 
Molarity(M) = moles of solute / volume of solution 
volume = 0.5l 
let x gms of glucose be needed 
moles of glucose = x / 180 (molecular weight = 180) 
M= x/180/0.5 
0.3=0.5x/180 
0.5x=54 
x = 54/0.5 
= 108gms 
glucose required = 108gms

How do you program a DA converter in the HCS12 microcontroller
How do you program a D/A converter in the HCS12 microcontroller? 
 
Solution 
 Many of the HCS12 family of 16-bit microcontrollers include support for Analog- 
to-Digital conversion. The HCS12 ATD converter is modular in design. At the time of 
publishing 8- channel and 16-channel implementations exist. The ATD is available on devices 
with automotive, industrial and consumer temperature ranges. All of the examples in this 
document are based on VDDA = 5V but the mo...
