elcise .1S.3 pp69i-698. Figure 8.85 shows an old cylindrical bore- hole that has been filled in part with silt and in part with water. Before the hole can be redrilled the water has to be pumped to the surface. We wish to estimate the work (en- ergy) required for this purpose water? Ground level 50 mAy Silt Figure 8.83 (a) As a first approximation, assume that the silting has been uniform - as indicated in Figure 8.85 and that the...

please explain the answer
1) Up until now we have always ignored air resistance. We should now add it. Let us just think of simple 1-dimensional problem, dropping a ball of mass m from a height H but 2 with air resistance. We can model the air resistance as a force proportional to the velocity, fair = bv. The coefficient bis a constant. (For this problem you can use calculus textbooks or wolfram alpha to do the calculus.) What are...

Newton's version of Kepler's Law Force Example Use what we know about the earth's orbit to estimate the mass of the sun. For this problem we can use Newton's form of Kepler's law Solving for the sum of the masses we get to use this law we need all our values to be kilograms, meters, and seconds. a 1AU-149.6x10P m and p- 1 year (365.25 days/year)(24 hours/day)(3600 seconds/hour)-3.15x 10" sec. Placing these values in to our equation we get M+...

Please help with Q1 a)b)c).
Question 1: In the lectures we considered simple projectile motion. Here we extend the description to include air resistance. For macroscopic objects in air, the dynamics equations including air resistance may be written V and ^- where m is the mass of the object, g is the acceleration due to gravity, y is the vertical direction, C is a dimensionless drag coefficient, A is the cross-sectional area of the object, pa 1.2kg/m3 is the density...

5. (30 points) We use rockets to launch sattelites into orbit, and lightening strikes can destroy both. In 1987, exactly this happened with an Atlas/Centaur rocket (it was an unmanned rocket; no one was injured). In this problem, we'll look at how an existing electric field caused an even stronger electric field to develop near the rocket's nose, causing lightening. If you wish to read more...

QUESTION: You are given a meterstick and asked to drill a small hole through it so that, when the stick is pivoted about a horizontal axis through the hole, the period of the pendulum will be a minimum. Where should you drill the hole?(give the distance from the end of the meterstick) Hint: The rotational inertia I of the pendulum can be calculated using the parallel axis theorem.
