Finding the height at which the water will strike the building from the hose. At what height h does the water strike building.
The motion of a human body through space can be precisely modelled as the motion of a particle at the body's center of mass, as we will study in Chapter 8. The components of the displacement of an a
An object at rest explodes into three pieces of equal masses. One moves east at 23 m/s, even as the second piece moves northwest at 14 m/s. What is the velocity of the third piece? Suppose each piec
The speed of a wave can be calculated from its wavelength and frequency. Understanding relationships between frequency, wavelength, period and speed of a wave.
Comfortable Acceleration assumes a rocket ship in deep space moves with constant acceleration equal to 9.8 m/s2 that give the illusion of normal gravity during the flight.
Develop an equation for the change in wavelength of a scattered photon by Compton Effect.
An electron is shot upward directly perpendicular to the lower plate of a parallel plate capacitor. Its initial velocity is 3.0 x 104 m/s. What must be the potential of the upper plate if the electr
A single slit of width 0.05mm is illuminated by parallel light of wavelength 600nm. How far is the sixth dark band from the central bright band as measured on a screen 20cm from the slit.
If 720-nm and 660-nm light passes through two slits 0.58 mm apart, how far apart are second-order fringes for these two wavelengths on a screen 1.0 m away.
While red light of wavelength 620 nm falls on a single slit, it creates a central diffraction maximum that is 8.80 mm wide on a screen 2 m away. How wide is the slit? How wide will the central peak
A wedge-shaped sliver of glass viewed from above is illuminated with 436-nm light. The sharp edge is dark. What is the thickness of the glass at the fifth bright fringe.
A single-lens camera forms a clear image of a distant object when the lens is 8 cm from the film. How far the lens should be moved to focus on an object 2 m away? What is the largest object that mig
Concentration of solids from liquid waste streams involves a combination of a settling tank and a centrifuge. The settling tank produces relatively clean effluent at a solids concentration of 10 gm-
A student undergoes a first displacement of 3.50 meters at an angle of 30degrees NORTH of EAST. The student undergoes a second displacement of 5meters at an angle of 45 degrees SOUTH of EAST. The x
A highway curve has a radius of 122 m. At what angle must the road be banked so that a car travelling at 26.8 m/s (60 mph) has no tendency to skid sideways on road? [Hint: No tendency to skid means
Determine the quantities of liquid in each tank at this initial steady state. Because of a flow controller failure, the liquid flow rate into tank 1 is suddenly doubled to VN=4 m3/min.
Tabulating the z factors and ideal volumes at each pressure value and calculate the specific gas gravity of the gas.
What is the smallest particle size (density 2.65 grams per cubic cm) that will be removed in a horizontal grit chamber 10 meters long and 1.0 meter deep if the flow rate is 1000 cubic meters per hou
Presume that we are designing a cardiac pacemaker circuit. The circuit is required to deliver pulses of 1-ms duration to the heart that can be modelled as a 500-? resistance.
Work out the escape velocity for an object started at the surface of the earth, going straight up. Overlook any complications due to the earth turning.
If one has two clocks at "infinity" and makes sure they run the equal, and after that lets one fall, what speed will the falling one have as it reaches the ground relative to the one at infinity.
Figure out the relative rates at which clocks go at two different distances r1 and r2 from the center of the earth (i.e. the ratio of 1 second at each distance).
Find out how high up a GPS satellite is relative to the center of earth and from that discover the ratio of clock rates on a GPS clock in orbit and one on the surface of the earth.
Solve how fast a GPS satellite is moving relative to someone on the ground and from that how much slower time runs where it is in orbit relative to someone on ground.
Multiply the time in question 3 by the speed of light to get a distance and evaluate it to the distance you had from question 1. That gives you an idea of how far off your GPS measurements would be
