This bear needs a break, so he climbs aboard a passing iceberg. The density of ice is 917 kg/m^3 and then density of sea water is 1025 kg/m^3. The iceberg has a volume of 5.2m^3.
a) What happens to the metacenter, the center of buoyancy, and the center of gravity when the bear gets on the iceberg (assuming the bear moves to the center of the iceberg)?
b) Can another animal get into the iceberg with the bear?
An alpha particle is moving at a speed of 5.0 × 105 m/s in a direction perpendicular to a uniform magnetic field of strength 0.040 T. What is the radius of the path of the alpha particle

A horizontal power line carries a current of 4880 A from south to north. Earth's magnetic field (75.1 µT) is directed toward the north and is inclined downward at 52.0° to the horizontal. Discover the magnitude of the magnetic force on 110 m of the l..
A telescope on earth uses a circular mirror of diameter 10 m (that is the aperture diameter). how close to each other could two stars, that are 20 light years away from the earth, be in order for the telescope to resolve them using a wavelength of..
An alpha particle (m = 6.7 x 10^-27kg, q = +3.2 x 10^-19C) has a speed of 30km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle throughout this motion. Find out the electric potential difference.
