The figure on the right illustrates a ball which is a uniform solid sphere having mass M and radius R. The ball is initially traveling in the positive direction with pure translational motion along a friction-less region of a horizontal surface (i.e. it slips with angular speed ω0-0). The initial translational speed of the ball is Vo. The friction-less region extends to a region having coefficient of kinetic friction Figure for WAH #10 V. Friction Friction-less No longer slipping '...
A positron (the electron's antiparticle) has mass 9.11 x 10-31kg and charge q0 = +e = +1.60 x 10-19 C. Suppose a positron moves directly away from an alpha particle, which has charge q = +2e. The alpha particle is stationary. When the positron is 1.00 x 10-10 m from the alpha particle, it is moving directly away from the alpha particle at 3.00 x 106 m/s. (a) What is the positron's speed when the particles are 2.00 x 10-10 m...

As shown in the figure, a wooden ball with mass m2 is initially at rest on a horizontal, frictionless table. A second wooden ball with mass my moving with a speed 2.00 m/s, collides with my. Assume my moves initially along the +x-axis. After the collision, my moves with speed 1.00 m/s at an angle of e = 53.0° to the positive x-axis. Assumem, -0.2009 and m, -0.300 kg) After the colon Before the collision (a) Determine the speed...
A. An α-particle has a charge of +2e and a mass of 6.64
× 10-27 kg. It is accelerated from rest through a
potential difference that has a value of 1.67 × 106 V
and then enters a uniform magnetic field whose magnitude is 2.49 T.
The α-particle moves perpendicular to the magnetic field at all
times. What is (a) the speed of the α-particle,
(b) the magnitude of the magnetic force on it, and
(c) the radius of its...

a) The initial ratio of deuterium (D) to hydrogen (H) in a planet's atmosphere was 175000; however, the present ratio is 1/1500 and the initial and final abundances of D are 5 x 10° atoms per m3 and 9 x 106 atoms per m2, respectively. What fraction of deuterium has been lost, and what fraction of hydrogen has been lost in this...
