Scientists have recently shown that a sample of cocaine can be traced to its country of origin by measuring the ration of carbon-13 to nitrogen-15 (both naturally occuring, stable nuclides) in the cocaine sample. Carbon-14 and Nitrogen-16, however, do not occur naturally and both of these nuclides undergo radioactive decay by the same process. Which type of radioactive decay is the most likely for carbon-14 and nitrogen-16?
A platform moves up and down in SHM, with amplitude 0.050 m. Resting on top of the platform is a block of wood. What is the shortest period of motion for the platform so that the block will remain in constant contact with it?
For a double-slit experiment with slit spacing 0.2 and wavelength 600, at what angular position is the path difference equal to one-fourth the wavelength.
A source emits sound uniformly in all directions. A radial line is drawn from this source. On this line, determine the radial positions of two points, 0.786m apart, such that intensity level at one point is 1.72 dB greater than that at the other.
Calculate the magnitude of B when the force on wire. The time constant of an RC circuit is 5.5 s. How much time t is required for the capacitor (uncharged initially) to gain one-half of its full equilibrium charge.
A stone is thrown upward with an initial speed of 20 m/s. What is its acceleration at the highest point of its trajectory?
A 0.65 percent C hypoeutctoid plain carbon steel is slowly cooled from about 950°C to a temperature just slightly above 723°C. calculate the weight percent austenite and weight percent proeutectoid ferrite in this steel. Explain it.
One tire is inflated to a pressure of 40 and goes a distance of 18.0 ; the other is at 105 and goes a distance of 93.4. Assume that the net horizontal force is due to rolling friction only and take the free-fall acceleration to be = 9.80.
Vector and scalar quantities. Part (a) Which of the following below is a scalar quantity? Part (b) What information do vectors quantities convey? Part (c) Which of the following is a vector quantity?
A rifle bullet is fired horizontally off the top of an ocean-based drill site. If the air resistance is negligible and the vertical distance to the water is 35 m, what additional information is needed to determine the time required for the bullet ..
The Achilles tendon inserts on the calcaneus at a distance of 8cm from the axis of the ankle joint. The force generated by the muscles attached to the Achilles tendon is 3000N, and the moment arm of this force is 5cm. a) Draw a free body diagram o..
A long, straight wire runs along the y-axis. The wire carries a current in the positive y-direction that is changing as a function of time according to i = 8 A + (0.2 A/s)t. A loop of wire is placed in the xy-plane near the y-axis. The loop has di..
