3.) If you were somehow able to stand on the surface of a neutron star, you would experience acceleration due to gravity of about 1.3 x 10^12 m/sec^2. [If you dropped a ball while standing there, the ball would quickly approach the speed of light in less than one second!] What is the acceleration due to gravity on the surface of a neutron star in \english" units of miles/hr^2? Explicitly show how you converted the units. 4.) There are three...

Dimensional Analysis: Often, we can almost derive formulas (up to an overall constant) just by knowing the units of the relevant quantities. Under the assumption that the pendulum's period can only depend on the pendulum's length L, m, maximum angle 0, and the strength of gravity g (with units [g]=m/s2), explain why we must have a relation like mass L T f(0) (Note that 0 counts as a unitless parameter here.) Asserting f(0)~ f(0) in this formula is the small...

A pendulum consists of a string of length L and a mass m hung at one end and the mass oscillates along a circular arc. Part a) Familiarize yourself with the derivation of omega = Squareroot g/L to hold. i) Explain succinctly how the angular frequency of oscillation omega = Squareroot g/L comes about from Newton's Law, where g is the gravitational acceleration. ii) One assumption required is the small angle approximation: sin theta = theta and cos theta =...

6. Use dimensional analysis to show that in a problem involving shallow water waves (Fig. P7- 87), both the Froude number and the Reynolds number are relevant dimensionless parameters. The wave speed c of waves on the surface of a liquid is a function of depth h, gravitational acceleration g, fluid density r, and fluid viscosity m. Manipulate your P's to get the parameters into the following form: pch Fr f(Re) where ReD gh ?, ?

Example 1 A star undergoes some mode of oscillation. Scientists/engineers have hypothesized that the oscillation frequency (cycles per second), o, is dependent on the density p and the radius R and the gravitational constant G which appears in Newton's law of universal gravitation. If you are not familiar with the gravitational constant, read the section on mass and weight in Chapter 4 (Dimensions/units) of the text. Therefore, w has dimensions (T), and P, R, Gare the governing parameters, with dimensions...

Sam is trying to move a dresser of mass m and dimensions of length L and height H by pushing it with a horizontal force F⃗ applied at a height h above the floor. (Figure 1) The coefficient of kinetic friction between the dresser and the floor is μk and g is the magnitude of the acceleration due to gravity. The ground exerts upward normal forces of magnitudes NP and NQ at the two ends of the dresser. Note that...
