What is the magnitude of the particle velocity and the acoustic
intensity at a distance of 0.25 m, 1mand 10m from a small spherical
source of radius 0.01 m and volume velocity of 0.02 m3/s operating
at a frequency of 200 Hz in air.
A particle that has a charge of 7.6 μC moves with a velocity of
magnitude 4 × 105 m/s along the +x axis. It experiences no magnetic
force, although there is a magnetic field present. The maximum
possible magnetic force that the charge with the given speed could
experience has a magnitude of 0.310 N. Find the magnitude and
direction of the magnetic field. Note that there are two possible
answers for the direction of the field.
A particle with a charge of −2.80×10−8 C is moving with an
instantaneous velocity of magnitude 42.5 km/s in the xy -plane at
an angle of 52.0 o counterclockwise from the +x axis.
Part A What is the direction of the force exerted on this
particle by a magnetic field with magnitude 2.00 T in the -x
direction?
Part B What is the magnitude of the force exerted on this
particle by a magnetic field with magnitude 2.00 T in...
An alpha particle travels at a velocity of magnitude 430 m/s
through a uniform magnetic field of magnitude 0.058 T. (An alpha
particle has a charge of charge of +3.2 × 10-19 C and a
mass 6.6 × 10-27 kg) The angle between the particle's
direction of motion and the magnetic field is 78°. What is the

An alpha particle travels at a velocity of magnitude 760 m/s
through a uniform magnetic field of magnitude 0.042 T. (An alpha
particle has a charge of charge of +3.2 × 10-19 C and a
mass 6.6 × 10-27 kg) The angle between the particle's
direction of motion and the magnetic field is 62°. What is the

The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. When grown in a uniform medium rich in salts and amino acids, these bacteria swim along zig-zag paths at a constant speed of 20 um/s. The figure shows the trajectory of an E. coli as it moves from point A to point E. Each segment of the motion can be identified by two letters, such as segment BC. What is...
when looking at the intensity of radiation (like light) as a
function of distance;
a) What power law should be used?
b) Why does the equation not work at close distances, but works
quite well at larger ones?
c) About how far away from a Geiger counter would a
Uranium-oxide glazed plate have to be in order to have the measured
count rate be indistinguishable from background?
What must the charge (sign and magnitude) of a 1.43-g particle
be for it to remain stationary when placed in a downward-directed
electric field of magnitude 690 N/C ?
What is the magnitude of an electric field in which the electric
force on a proton is equal in magnitude to its weight?
On May 12, 2008, a certain country had a 7.8 magnitude
earthquake. What was the intensity of that earthquake? (Round your
answer to two decimal places.)
