Q. A uniform electric field of magnitude 290 V/m is directed in the negative y direction as shown in the figure below. The coordinates of point A are (-0.200, -0.300) m, and those of point B are (0.400, 0.500) m. Calculate the potential difference VB - VA, using the blue path.
Q. A 231- projectile, fired with a speed of 105 at a 57.0 angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally. Determine the energy released in the explosion.
Nitrogen and oxygen in their liquid states have densities only 0.80 and 0.90 that of water. Atmospheric pressure is due primarily to weight of nitrogen and oxygen gas in the air. If atmosphere liquefied would its depth be greater or less than 10.30 m..
A brick is thrown vertically upward with an initial speed of 4.90 m/s from the roof of a building. If the building is 98 m tall, how much time passes before brick lands on the ground.
A horizontal force of 213 N is exerted on a 1.90 kg discus as it rotates uniformly in a horizontal circle (at arm's length) of radius 1.60 m. determine the time for one revolution of the discus. Round the answer to 2 decimal places.
wheel A of radius rA = 11 cm is coupled by belt B to wheel C of radius rC = 20 cm. The angular speed of wheel A is increased from rest at a constant rate of 1.6 rad/s2. Find out the time needed for wheel C to reach an angular speed of 100 rev/min,..
A 10 μF capacitor is charged to 15 V. It is next connected in series with an uncharged 5.00-μF capacitor. The series combination is finally connected across a 50.0-V battery, as diagrammed. Find out the new potential differences across the 5-μF an..
What is the kinetic energy of a 1,500 kg car with velocity of 72.0 km/hr? How much work must be done on the car to bring it to a complete stop.
A man pushes a lawn mower on a level lawn with a force of 186 N. If 35 percent of this force is directed downward, how much work is completed by the man in pushing the mower 6.5 m.
A proton starting from rest is accelerated in a cyclotron to a speed of 3.0•106 m/s. Find the work done on a proton by the electrical force of the cyclotron.
The electricity received at an electric substation has a potential difference of 2.80 10^5V. If the requires output is 440V, what must be the ratio of the turns of the step-down transformation.
Two objects with masses 5.60 kg and 1.40 kg hang 0.500 m above the floor from the ends of a cord 6.80m long passing over a frictionless pulley. Both objects start from rest. Find the maximum height reached by the 1.40kg object.
What are the velocities of the two people after the snowball is exchanged? Disregard friction between skate and the ice.
Vector A has a magnitude of 9.10 units and makes an angle of 54.0° with the positive x-axis. Vector B also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods find the following.
