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 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 many transcontinental flights would a person have to take in a year to raise the annual radiation dosage to 0.2Sv How many transcontinental flights would a person have to take in a year to raise the annual radiation dosage to 0.2Sv Solution Average person receive around 0.08 mSv radiation dosage in a transatlantic flights , so doing the maths 2.5 flights

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...
