use bernoulli's equation (P+1/2pv^2+pgy=constant) to explain why a house roof is easily blown off during a...
1. Usually blood pressure is measured on the arm at the same level as the heart. Why? How would the results differ if the measurement were made on the leg instead? 2. Use Bernoulle’s equation to explain why a house roof is easily blown off during a tornado or hurricane.
Part 1 Roofs of houses are sometimes “blown off” during a tornado or hurricanes. Explain this using Bernoulli’s principle. Part 2 Why can one say that airplane wings and race car spoilers are inverses of each other? What is the use for each of them and how do each work here? Please no hand wrriting
Can someone explain what is happening in this diagram why are
there two exits for pressure P in the actual tube.

3(b) Bernoulli's equation states that P+ pgh-const (i) Explain what each of the three terms on the left hand side of the equation represents. What is the physical interpretation of this equation? 151 The surface pressure on Venus is 92 atm, and the acceleration due to gravity is 0.894g. A space mission leaves a cylindrical tank of benzene standing upright on the planet's surface. The tank is sealed and is pressurised so that the pressure inside the tank at its...
If a is a square mod p . Then explain why “a^(p-1)/2≡1 (mod p)” is this true.
Laguerre's equation ty" + (1 – 2)y' + py=0) where p is a constant, is a confluent hypergeometric equation. (a) Show that the equation has x = 0) as a regular singular point with indicial root 0; (b) Show that one solution of the equation is 1+ Ž (–1)n-P(p – 1) ...(p+1-n) n=1 (n!) (©) Show that the only solutions bounded near the origin are constant multiples of the solution in (b).
2. An airplane is heading due north at an airspeed of 950 km/h, but there is a constant wind blowing from the northeast at 100 km/h. We will use vectors to work out how far off course the plane is blown, and what its ground speed is. (a) Write down a vector, p, that represents the intended flight path of the plane in one hou. (b) Write down a vector, w, that represents the movement of a particle caught in...
Can anyone explain to me why I've seen the equation Bias= 2^exponentbits -1 and Bias= (2^exponentbits -1)-1 I'm confused on what equation to use. Can you please clarify? Thanks
1) Ben Bitdiddle is building a house. Explain how he can use the principles of hierarchy, modularity, and regularity to save time and money during construction. 2) Convert the following two’s complement binary numbers to decimal. (a) 1010 (b) 110110 (c) 01110000 (d) 10011111
1. Calculation: Using the Henderson-Hasselbalch equation, explain mathematically why a solution is at a pH below the pKa for an acid that more than 50% of the molecules have the proton on (not off). 2. Calculation: If you have a pH of 5.5 for a weak acid with a pKa of 4.76, then is there more A- or more HA in the solution? Explain why in words using your knowledge of positive or negative log numbers.
