The electrical field within a continuous distribution of charge is given by the equation E= cxi+cyj+czk, where c= 1N/C(m) is a constant, (x,y,z) are cartesian coordinates, and (i,j,k) are the cartesian unit vectors.
a) Write the equation for E in terms of the position vector r. What kind of symmetry is associated with this funciton?
b) What is the electric flux through a spherical surface of radius 1m centered at the origin of the coordinates? How much electrical charge is located inside this sphere?
c) What is the electric flux through a cube 1 m on a side centered at the origin of the coordinates? How much electrical charge is located inside this cube?
An atomic nucleus of mass 288 u moving at 405m/s emits an alpha particle of mass 4.0 u in the direction of its velocity. If the remaining nucleus slows to 360m/s, what velocity does the alpha particle have when it is emitted.
A 20.0- projectile is fired at an angle of 60.0 above horizontal with a speed of 80. At the highest point of its trajectory, projectile explodes into two fragments with equal mass, one of which falls vertically with zero initial speed. You can ign..
An 82 kg parachutist descends through a vertical height of 350 m with constant speed. Find out the increase in entropy produced by the parachutist; assume the air temperature is 21 degrees C.

A ship sets out to sail to the point 158 km due north. An unexpected storm blows the ship to a point 134 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive an..
The height of a door is measured by four people and their measured values are 217.0 cm, 217.9 cm, 217.3 cm, and 217.6 cm, What is the standard deviation for the four measurements
A small .500 kg object moves on a frictionless horizontal table in a circular path of radius 1 m. The angular speed is 6.28 rad/s. The object is attached to a string of negligible mass that passes through a small hole in the table at the center of..
A computer disk is 8.0 cm in diameter. A reference dot on the edge of the disk is initially located at theta=45 degrees. The disk accelerates steadily for 0.50 s, reaching 2000 rpm, after those coasts at steady angular velocity for another 0.50 s.
For a damped oscillator with a mass of 380g, the spring constant 120 N/m and a damping coefficient of 76 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 28 cycles.
A 0.6410-kg ice cube at -12.40°C is placed inside a chamber of steam at 365.0°C. Later, you notice that the ice cube has completely melted into a puddle of water.
In a television, electrons shoot down the picture tube and strike fluorescent material on the screen, causing light to be emitted and producing the picture. assume that a certain set, the electrons are accelerated from rest 2.0 x 10^8 ms-1 in abou..
