On planet X, the alien residents use a temperature scale in which they define 0 degrees X to be the melting point of nitrogen and 100 degrees X to be the boiling point of nitrogen.
In the same way that we related the Fahrenheit and Celcius scales, derive an expression that relates the temperature in degrees X to the temperature in degrees C.
1.) What temperature difference in X degrees does a temperature change of 1 C degree correspond to?
2.) What temperature in degrees X does water freeze?
3.) What tempeture in degrees X does absolute zero correspond to?
To measure the static friction coefficient between a 4.33-kg block and a vertical wall, the setup shown in the drawing is used. A spring (spring constant = 461 N/m) is attached to the block.
A circular-motion addict of mass 90 kg rides a Ferris wheel around in a verticalcircle of radius 10 m at a constant speed of 6.3 m/s. What is the period of the motion?
A 0.58-kg mass is hanging from a spring with spring constant 20 N/m. Then the mass is displaced from the equilibrium by 2.9 cm and let go. estimate the resulting angular frequency of the oscillation
In a non-uniform gas, the equation of state is valid locally, as long as the density does not change too rapidly with position. Consider a column of ideal gas under gravity at constant temperature. Find the density as a function of height, by bala..
For a damped oscillator with a mass of 350 g, a spring constant 59.00 N/m and a damping coefficient of 89 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 30 cycles.
A relief airplane is delivering a food package to a group of people stranded on a very small island. What is the velocity of the plane if the pilot successfully drops the package from a horizontal distance, D, equal to 600 m from the site
A 20 liter tank of helium is at a pressure of 172kPa at a temperature of 0 C. What is the speed of the helium atoms in the tank at this new volume
A small object oscillates back and forth at the bottom of a frictionless hemipherical bowl. The radius of the bowl is R, and the angle theta is small enough that the object oscillate in simple harmonic motion.
