Q. A particle with a mass of 2.00e-16 kg and a charge of 29.0 nC starts from rest, is accelerated by a strong electric field, and is fired from a small source inside a region of uniform constant magnetic field 0.710 T. The velocity of the particle is vertical to the field. The circular orbit of the particle encloses a magnetic flux of 15.0 µWb.
Automobile engine slows down from 4500 rpm to 1200 rpm in 2.5 s. compute (a) its angular acceleration, assumed constant and (b) total number of revolutions the engine makes in this time.
Six artificial satellites complete one circular orbit around a space station in the same amount of time. Each satellite has mass and radius of orbit. The satellites fire rockets that provide force needed to keep a circular orbit around the space stat..
Two crates, of mass 75 kg and 105 kg, are in contact and at rest on a horizontal surface. A 732 N force is exerted on the 75.00 kg crate.
Intuitively, the man will not catch the bus unless he is running fast enough. In mathematical terms, there is a constraint on the man's speed so that the equation above gives a solution for that is a real positive number.
A body travels a distance of 3km towards east and 4 km towards north and finally 9 km towards east. what is the total distance travelled and displacement of body.
Certain stars at the end of their lives are thought to collapse combining their protons and electrons together to form a neutron star. Such a star could be thought of as a giant atomic nucleus.
At some automobile toll-collecting stations, the thin metal wire sticks up from the road and makes contact with cars before they reach the toll collector. What is the reason of this wire.
The specific heat of mercury is 138 J/kg Co Determine the latent heat of fusion of mercury using the following calorimeter data: 1 kg of solid Hg at its melting point of -39.0º C is placed in a 0.620 kg aluminium calorimeter with 0.40 kg of water ..
