(a) find the potential at point p. (q = 2.5 x 10-9c, a = 50 cm) (b) how much work by an external force is required to move a charge of – 3 µc to point p. (c) if the particle (mass = 5.0 µg) were released from rest at point p, what would be […]
What is the single most important parameter in determine the material removal rate in a machining process?
True or false the light that is emitted from a semiconductor, upon external stimulation, is longer and longer in wavelength as the particle size of the semiconductor decreases.
The gravitational acceleration on a planet’s surface is 16.0 m/s2. what is the gravitational acceleration at an altitude of one planet diameter above the surface of the planet?
At a pressure of one atmosphere oxygen boils at −182.9°c and freezes at −218.3°c. consider a temperature scale where the boiling point of oxygen is 100.0°o and the freezing point is 0°o. determine the temperature on the oxygen scale that corresponds to the absolute zero point on the kelvin scale.
The desk has a weight of 75 lb and a center of gravity at g. determine its initial acceleration if a man pushes on it with a force f = 60 lb. the coefficient of kinetic friction at a and b is mk = 0.2.
Consult concept simulation 6.1 in preparation for this problem. a golf club strikes a 0.065-kg golf ball in order to launch it from the tee. for simplicity, assume that the average net force applied to the ball acts parallel to the ball’s motion, has a magnitude of 6170 n, and is in contact with the […]
Calculate wa, the work done by the gas as it expands along path a from v0 to va=rvv0. express wa in terms of p0, v0, and rv.
68 kg tennis ball is given an angular momentum of .00272 kgm2/s when struck by a racquet. if its radius of gyration is 2 cm, what is its angular velocity
A 129-kg astronaut (including space suit) acquires a speed of 2.30 m/s by pushing off with her legs from a 1850-kg space capsule. use the reference frame in which the capsule is at rest before the push. part a what is the velocity of the space capsule after the push in the reference frame?
