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
If the object is located between the focal point and the mirror surface where is the object to be located if it is virtual, upright, and magnified.
Determining position of an object in front of a screen to obtain a image of size twice larger than its original size on the screen.
In a die-casting operation 0.1 kg charges of molten zinc alloy at 410 degrees C are injected at a rate of 120 charges per hour. The liquid metal has the specific heat of 500 J kg-1 K-1 and a freezi
The original angular velocity of the blade is ω0 = 0.5 rad/s. After 3 seconds, blade is turning with an angular velocity of ω = 2 rad/s as shown in the diagram. Conclude the distance po
Determining the maximum vertical acceleration given to a pipe, and the normal reactions acting on the wheels.
Estimate the gravitational force exerted by a shuttle on Earth.
The purposes of this lab are to learn the use of a vernier caliper, make some basic length measurements and to use these measurements to calculate volumes and densities.
Develop a formula for finding the time constant of the liquid level system shown in the below figure. When the average operating level is h0. The resistance R is linear.
Make the following unit conversions for parts (a) through (e) in table below. Show the work using a step-wise approach (e.g., show the conversions of the numerator and denominator separately).
Determining the surface tension (adhesion) force on water inside a tube and height to which the water rises in the tube.
What is the ratio of the dynamic viscosity of air to that of water at standard pressure and a temperature of 20 o C? What is the ratio of the kinematic viscosity of air to that of water for the equa
