Compare the kinetic energies of two objects, A and B, identical in every respect except one. Assume that the single difference is: Object A has twice the velocity of B. Object A moves north, B south. Object A moves in a circle, B in a straight line. Object A is a projectile falling vertically downward; B is a projectile moving vertically upward at the same speed. Object A consists of two separate pieces attached by a light string, each equal in...
Two capacitors are identical, except that one is empty and the other is filled with a dielectric (k = 3.7). The empty capacitor is connected to a 12 -V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric so that it stores the same amount of electrical energy as the empty capacitor?
Two capacitors are identical, except that one is empty and the other is filled with a dielectric (k = 4.1). The empty capacitor is connected to a 16-V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric so that it stores the same amount of electrical energy as the empty capacitor? V2 = the tolerance is +/-2%
Two capacitors are identical, except that one is empty and the other is filled with a dielectric (κ = 3.61). The empty capacitor is connected to a 16.0-V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric so that it stores the same amount of electrical energy as the empty capacitor? V2 = ---Select--- F C J V
7 Two capacitors are identical, except that one is empty and the other is filled with a dielectric (κ = 3.22). The empty capacitor is connected to a 14.0-V battery. What must be the potential difference across the plates of the capacitor filled with a dielectric so that it stores the same amount of electrical energy as the empty capacitor? V2 = ---Select--- V C F J
Two objects are maintained at constant temperatures, one hot and one cold. Two identical bars can be attached end to end, as in part a of the drawing, or one on top of the other, as in part b. When either of these arrangements is placed between the hot and the cold objects for the same amount of time, heat Q flows from left to right. Find the ratio Qa/Qb. (b) Qa/Qb= Number i Units
Two identical objects (such as billiard balls) have a one-dimensional collision in which one is initially motionless. After the collision, the moving object is stationary and the other moves with the same speed as the other originally had. Show that both momentum and kinetic energy are conserved.
Consider two data sets A and B. The sets are identical except the high value of the data set B is three times greater than the high value of data set A. (a) How do the median of the two data sets compare? (b) How do the means of the two data sets compare? (c) How do the standard deviations of the two data sets compare? (d) How do the box- and –whisker plots of the two data sets compare?...
A company issues two bonds that identical in all ways except one is callable and the other is not. Which one will investors pay more for (i.e., accept a slightly lower return)? Explain why.
Two identical objects are in thermal contact. One is at a high temperature (T-hot) and the other is at a cool temperature (T-cool). Assume that this system is isolated, i.e. there is no interaction with the surroundings. Using the thermodynamic definition of entropy, explain why heat always flows from T-hot to T-cool, and never the other way around.
