Q. A very long solenoid of circular cross section with radius r= 5.4cm has n= 86.0 turns/cm of wire. An electron is sitting outside the solenoid, at a distance r= 5.90 cm from the solenoid axis. What is the magnitude of the force on the electron while the current in the solenoid is ramped up at a rate of 27Amps/second?
find out the change in electric potential energy. For lengths of 1.000 m, 0.750 m, and 0.500 m, total time.
A crate of 31.9- tools rests on a horizontal floor. You exert a gradually increasing horizontal push on it and observe that the crate just begins to move while your force exceeds 345. After that you must reduce your push to 247 to keep it moving at a..
Quarks carry spin 1/2. Three quarks bind together to make a baryon (such as the proton or neutron); two quarks (or more precisely a quark and an anti-quark) bind together to make a meson (for example the pion or the kaon). Suppose the quarks are i..
A student throws a set of keys vertically upward to her sister in a window 4.0 m above. The keys are caught 1.5 s later by the sister’s outstretched h&. Find initial speed were the keys thrown?
You pull with a force of 295 N on a rope that is attached to the block of mass 20 kg, and the block slides across the floor at a constant speed of 1.2 m/s. The rope makes an angle of 35 degrees with the horizontal.
When the plunger is pushed, contents of the syringe are forced throughout a hollow needle (also of circular cross-If a 4.0 N force is applied to plunger and diameters of the plunger and the needle are 1.20 cm and 2.50 mm, correspondingly, what force ..
A major-league pitcher can throw a baseball in excess of 44.2m/s. If a ball is thrown horizontally at this speed, how much would it drop by the time it reaches the catcher who is 16.10 m away from the point of release.
How much work did movers do (horizontally) pushing a 140{rm kg} crate 10.60 m across a rough floor without acceleration, if the effective coefficient of friction was 0.700.
A ship's anchor weighs 5000 N. Its cable passes over a roller of negligible mass and is wound around a hollow cylindrical drum of mass 380kg and radius 1.10m. The drum is mounted on a frictionless axle. The anchor is released and drops 16 m to water.
What is an average velocity of the train throughout run
Assume the helmholtz coil consists of two sets of coaxial wire loops with 15 turns of radius R=75.00 cm, that are separated by R, and each coil carries the current 0.123A flowing in the same direction. Compute the magnitude and direction of magnetic ..
A 2.50 syringe has an inner diameter of 4 , a needle inner diameter of 0.24 , and a plunger pad diameter (where you place your finger) of 1.2 cm. A nurse uses syringe to inject medicine into a patient whose blood pressure is 140/100.
