An electron in the beam of a cathode-ray tube is accelerated by a potential difference of 2.00 kV. Then it passes through a region of transverse magnetic field, where it moves in a circular arc with a radius of 0.180 m. What is the magnitude of the field?

Calculate the velocity of a car traveling in a straight path due east with a distance of 16 meters in 2 seconds. question 1 options: a)32 m/s b)32 m/s e c) 8 m/s e d) 8 m/s

What happens to the vapor pressure of a substance when its surface area is increased at constant temperature?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
