11- Einteins theory concludes that at lower temperature, the specific heat: a. drops linear with increase of temerature , b drops linearly with decrease of temperature. C drops
exponentially with decrease of temperature
d remains constant

In order of decreasing light-transmitting capabilities of materials, which is the correct sequence? a. transparent -> translucent -> opaque b. opaque -> transparent -> translucent c. opaque -> translucent -> transparent d. translucent -> transparent -> opaque

Abeam of electrons moves at right angles to a magnetic field of 4.5 × 10-2 tesla. if the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? the value of q = -1.6 × 10-19 coulombs.

When solid surfaces slide over each other the kind of friction that occurs is called friction
