Q. Four charges Aq,Bq,Cq, and Dq (q = 3.00 × 10-7C) sit in a plane at the corners of a square whose sides have length d = 84.0 , as shown in the diagram below. A charge, Eq, is located at the origin at the center of the square. DATA: A = 8, B = 6, C = 5, D = 4, E = 4. Consider the charge at the center of square. What is the net force, in the x-direction on this charge?
Q. A 13g rifle bullet traveling 150m/s buries itself in a 3.7 kg pendulum hanging on a 2.9 m long string, which makes the pendulum swing upward in an arc. Resolve the horizontal component of the pendulum's maximum displacement.
A 20.00 kg wood ball hangs from the 1.10 long wires. The maximum tension the wire can withstand without breaking is 600 N. A 0.710 kg projectile travelling horizontally hits and embeds itself in the wood ball. What is the largest speed this projectil..
find the work done to move the particle from x = 0 to x = 10.0 m by graphically determining the area under the F versus x graph. (Do this on paper. Your instructor may ask you to turn in this graph.)
A particle has an acceleration of 6.39 for 0.28. At the end of this time the particle's velocity is 9.31 .What was the particle's initial velocity.
Many communications satellites orbit the earth in geostationary orbits. (They appear to remain in the same positions in the sky for observers on the earth's surface.) If such a satellite orbits at a height of 40,000 km, estimation the time delay in a..
In daily life we see many cases of people who are caught misrepresenting things who soon thereafter are excused and accepted by their contemporaries. How is This different in science.
An ice block is pushed horizontally on a frictionless surface with initial velocity v0. At some point, it comes to the nearly semicircular bump with a radius R=0.42m and the height h=0.33m above the ground.
A 200 g ball on a 60 cm long string is swung in a vertical circle about a point 200cm above the floor. The tension in the string when the ball is at very bottom of the circle is 4.4 N.
What is the average induced emf in the coil in mV. If he is crossing a river where the current is 1.60 km/h, in what direction should his boat be headed if he wants to reach the point directly opposite his starting point.
