if k = 1.0012, by what factor will the neutron population be increased after 10 generations?

An electron and a neutral carbon atom of polarizability are at a distance r apart (r is much greater than the diameter d of the atom). Due to polarization of the atom by the electron, there is a fo

A charge of +1.62 10 9 C is placed at the origin, and another charge of +6.27 10 9 C is placed at x = 2.4 m. The value of the Coulomb constant is 8.98755 109 N m2/C2. Find the point (coordin

Part 1 Two identical conducting spheres are placed with their centers 0.48 m apart. One is given a charge of +1.1 10 8 C and the other a charge of 1 10 8 C. The Coulomb constant is 8.98755 10

determine the algebraic sign (+, , or 0) of the velocity and acceleration of the object at the time specified. For this motion, the positive y axis is upward. An elevator is moving downward when som

A particle of mass M moves in one dimension along the positive x axis, under the influence of two forces. The first force is a constant force, with magnitude B and direction toward the origin. The sec

show directly that the time rate of change of the angular momentum about the origin for a projectile fired fromthe origin(constant g) is equal to the moment of force(or torque) about the origin.

1. A particle leaves the origin with an initial velocity = (6.87) m/s and a constant acceleration = (  2.48  4.29) m/s2. When the particle reaches its maximum x coordinate, what are (a) its velo

At time t = 0, a projectile is launched from ground level. At t = 2.00 s, it is displaced d = 41 m horizontally and h = 67 m vertically above the launch point. At the instant it reaches its maximum he

In Fig. 434, a stone is projected at a cliff of height h with an initial speed of 45.0 m/s directed at an angle 0 = 62.0 above the horizontal. The stone strikes at A, 5.37 s after launching. Find (

Tips for Asking Questions
 Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
 Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price speeds up the process by avoiding any unnecessary price negotiations.
Sample Questions
 The Earth’s rate of rotation is constantly decreasing, causing the day to increase in duration. In the year 2000 the Earth takes about 0.548 s longer to complete 365 revolutions than it did in the year 1900.
 (a) What is the average angular acceleration of the Earth?
 (b) If this average acceleration remains constant, in what year will the Earths rotation come to rest?
1. Can you show me step by step how to solve this problem?:
 A spherical balloon is made from a material whose mass is 3.00kg. The thickness of the material is negligible compared to the 1.5m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19kg/m^3. Find the absolute pressure of the helium gas
