1) If all the energy contained in a 46-gram golf ball could be used, how long could it power one 100-wattt light bulb? Hint: Think about the "Equivalence" of "mass" and "energy" Data: t= E/P, where t=time (in seconds), E= energy (in Joules), and P = power consumption in "watts" Note Reduce your final result to "meaningful terms"
2) Vectors of force question is attached
3) Hubble Law: A distant galaxy is determined to be 150 million light years distant and moving away from us; using the Hubble law determine its velocity in terms of "0.XX.C"
4) Determine the binding energy in joules of a cobalt atom. Data: # of protons in the nucleus: 27. # of neutrons in the nucleus:32. Mass of cobalt atom: 97.958205 x 10^-27 kg
5) A subatomic particle known as a "pion" has an average life span of 2.6 x 10^-8 sec. How long does the particle exist from the perspective of the laboratory observer if the pion moves pas the observer at 0.67c?
If you twirl a small 9.0-g wooden ball in a circle at 3.0 revolutions per second on a light 11-cm string, approximately how many units of angular momentum does it have
how many turns should a solenoid of cross-sectional area 0.035 m2 and length 0.39 m have if its inductance is to be 48
A string is wrapped tightly around a fixed pulley that has a moment of inertia of 0.0352 kg m2 and a radius of 12.5 cm. The string is pulled away from the pulley with a constant force of 5.00 N. As the string unwinds the pulley begins to rotate. What..
after landing a jetliner on a straight runway taxis to a stop at an average velocity of -35.0 . if the plane takes 7.00
A pulley, with a rotational inertia of3.2×10-3kg m2 about its axleand a radius of 8.0 cm, is acted on by a force applied tangentially at its rim. The force magnitude varies in time as F =0.46t + 0.32t2, where F is in newtons if t is given inseconds..
A source of sound waves of frequency 1.2 kHz is traveling during the air at 0.25times the speed of sound.What is the frequency of the sound received by a stationary observer if the source moves toward her?
A golf ball is hit on a 7.2m tall hill at 23m/s and 30° above the horizontal, what is its velocity at the peak of its flight
You are examining a flea with a converging lens that has a focal length of 3.70cm. If the image of the flea is 6.00 times the size of the flea, how far is the flea from the lens
The bungee cord acts just like a coil extension spring with constant k = 4 lbf/ft and its unstretched length is L= 6 ft. At first the cord is loosely dangling but then becomes taut and goes into tension as soon as the skaters
A 14.0 V battery is connected in series by a resistor and an inductor. The series circuit has a time constant of 600 µs, and the maximum current is 303mA. What is the value of the inductance?
Figure (a) shows an element of length ds =1.00 µm in a very long straight wire carrying current. The current in that element sets up a differential magnetic field dB at points in the surrounding space
A spaceship is visiting Planet X. While descending to the surface,its rockets produce 25 kN of upward thrust and the spaceship%u2019s speed decreases at a rate of 0.15 m/s2. What is the mass of the spaceship
