A particle has an acceleration of 6.19 m/s^2 for 0.350 s . At the end of this time the particle's velocity is 9.26 m/s What was the particle's initial velocity?
Use this technique to find formula for the intensity of a sound, in terms of sound level and the reference intensity. There will be a quantity involved in the calculations. When you enter your answer, leave off the unit.
An athlete starts at point A and runs at a constant speed of 6m/s around a round track 100 m in diameter, what is x component of this runner's average velocity between points A and B.
A charge of -2.85 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass, which has a radius of 0.105 m.
Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 = 0.100 N. Using this information, find the initial charge on each sphere, q1 and ..
A long, solid insulating cylinder of radius R = 1 mm has a uniform volume charge density and a total linear charge density of Lambda = 3:610^ -9 C/m.
A music store has jazz, classical, country-western and rock music albums on tapes and CDs in the following quantities finding the probability.
A cardinal (Richmondena cardinalis) of mass 4×10-2 kg and a baseball of mass 0.143 kg have the same kinetic energy. What is the ratio of the cardinal's magnitude p_c of momentum to the magnitude p_b of the baseball's momentum.
What will be the equilibrium temperature when a 223 g block of copper at 258 C is placed in the 178 g aluminium calorimeter cup containing 874 g of water at 13.2 C.
A 40 percent efficient electric power plant produces 900MW of electric power and discharges waste heat into 30 C ocean water. Suppose the waste heat could be used to heat homes during the winter instead of being discharged into the ocean. A typical A..
A 78-kg base runner begins his slide into second base when he is moving at a speed of 4.2 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches base.
a) Determine the magnitude and direction of the electrostatic force acting on particle A in the figure given below due to particles B and C . The values of the charge on these particles are indicated in the figure.
Paul is what most people consider a "jock." He is the captain of both the football and wrestling team and he also plays hockey. Upon entering Mrs. Title's class she figured that he would not take course seriously nor would he excel in class. She p..
