An alpha particle (a He nucleus, containing two protons and two neutrons and having a mass of 6.56×10?27kg ) traveling horizontally at 35.0km/s enters a uniform, vertical, 1.10Tmagnetic field.
1) What is the diameter of the path followed by this alpha particle?
2) What effect does the magnetic field have on the speed of the particle?
3) What are the magnitude of the acceleration of the alpha particle while it is in the magnetic field?
4) Explain why the speed of the particle does not change even though an unbalanced external force acts on it.
A bat strikes a 182g ball with a force of 109-N at an angle of 57° above the horizontal. What is the ball's vertical acceleration (positive for upward, negative for downward).
Determine the maximum percent uncertainty it will produce in this experiment if we did not align the apparatus to minimize its effects
Consider the following vector fields: C=2x(x-direction), D=5x(y-direction), F=4s(phi-direction), G=3s(s-direction), For each field which could be magnetic, calculate the current density at the origin in two different ways
A man is running at speed c (much less than the speed of light) to catch a bus already at a stop. At t=0, while he is a distance b from the door to the bus, the bus starts moving with the positive acceleration a.
An electric motor rotating a workshop grinding wheel at a rate of 9.90 x 10^1 rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 1.70 rad/s2.
Two sound sources radiating in phase at a frequency of 485 Hz interfere such that maxima are heard at angles of 0 and 22° from a line perpendicular to that joining the two sources. Find out the separation between the two sources.
What is the attractive force between the protons. A rocket rises vertically, from rest, with the acceleration of 3.0 m/s2 until it runs out of fuel at an altitude of 1100 m. After this point, its acceleration is that of gravity, downward.
illustrate a diagram to show the forces acting on the aircraft while it is flying in a horizontal circle with its wing banked at an angle to horizontal.
An iron bolt of mass 79.0 g hangs from a string 32.4 cm long. The top end of the string is fixed, Find the tension in the string and Find the magnetic force on the bolt
A spring has a force constant of 100 N/m and an unstretched length of .07 m. One end is attached to a post that is free to rotate in the center of a smooth table.
A swimming pool has dimensions 32 m 9 m and a flat bottom. The pool is filled to a depth of 1.50m with fresh water. What is the force exerted by water on the bottom.
If a 2.00{rm kg} mass is now attached to the end of the spring, where will the end of the spring line up with the ruler marks?
