Q. A planet moves in an elliptical orbit around the sun. The mass of the sun is Ms. The minimum and maximum distances of the planet from the sun are R1 and R2, in that order.
Using Kepler's 3rd law and Newton's law of universal gravitation, find the period of revolution of the planet as it moves around the sun. Suppose that the mass of the planet is much smaller than the mass of the sun. Use for the gravitational constant. Articulate the period in terms of G, Ms, R1, and R2.
Two points are located on a rigid wheel that is rotating with an increasing velocity about fixed axis. The axis is perpendicular to the wheel at its center. Point 1 is located on the rim and point 2 is halfway between rim and axis .at any given insta..
What is the focal length of this mirror. If the object is 25 cm in front of the mirror, what is the image distance.
Then find the force between them as a function of distance h. describe why the sign of the force does (or does not) make sense to you.
What is the frequency of ultrasound in a medium if he wave length is 3.0 x 10^-3 m and velocity is 1300 mm/ms.
Sea Launch mission planners are going to launch their Russian launch vehicle from a Lo = 3 degrees into LEO with an inclination of 34 degrees and the longitude of ascending node of 124 degrees. Current LST at the launch site is 1140.

110 grams of boiling water (temperature 100° C, heat capacity 4.20 J/gram/K) are poured into an aluminum pan whose mass is 1000 grams and initial temperature 24° C (the heat capacity of aluminum is 0.9 J/gram/K).
How much work is completed by the system in this process. Determine the increase in entropy produced by the parachutist; assume the air temperature is 21 degrees C. How much work is completed by the system in this process.
A fully loaded station wagon has a mass of 1690 kg. If each of its four tires is inflated to a gauge pressure of 211 kPa, what is the total tire area in contact with road.
A little cat, Bella, walks in a straight line, which we shall call the x axis, with positive direction to the right. As an observant scientist, you make measurements of her motion and construct a graph of the little feline's velocity as a function..
An object of mass 555 grams sitting on a plane inclined at 35 degrees doesn't slide. Now the plane is lifted to the angle of 50 degrees and the object slides down plane knowing that the coefficient of kinetic friction is 0.44, find out the coefficien..
For a rough calculation, we shall assume that the doctor is 50 from the baby (she is likely to be even closer at delivery), has a mass of 75.00, and can be modelled as a uniform sphere.
