a block of mass 1500kg lying steady on horizontal surface of a table needs 200N horizontal force to come in motion.
What is coefficient of static friction between the block and the surface of table
Water (which can be considered to be an ideal fluid for this question) flows at a rate of 25L/min through a pipe of diameter7.0cm at a pressure of 6.0Pa. At one point in the horizontal pipe, calcium deposits reduce the cross-sectional area to 30cm2. ..
he rolling resistance for steel on steel is quite low; the coefficient of rolling friction is typically r=0.002. How far will the locomotive move during this time
Use Maxwell-Ampère's equation to calculate the maximum strength of the B-field on the perimeter of the plates; when is the B-field maximum
A meteor of mass 575 kg has speed 90.0 m/s when it is 800 km above the surface of the Earth. It is falling vertically and strikes a bed of sand. What is the average force exerted by the sand on the meteor
A 5.34kg object moving at a speed of 1.3m/s in the postive x-axis collides wth a 3.20kg moving at 2.5m/s in the opposite direction, sticking together as a result
A planet of mass m = 7.85 × 1024 kg is orbiting in a circular path a star of mass M = 4.35 × 1029 kg. The radius of the orbit is R = 8.15 × 107 km. What is the orbital period (in earth days) of the planet Tplanet?
Blood contains both negative and positive ions. In a certain patient being tested, the speed of these ions in a large artery is gauged at 0.60m/s. The patient is placed in a uniform magnetic field of magnitude 0.20T .If a potential dissimilarity of 1..
The attractive electrostatic force between the point charges 7.14×10?6 and has a magnitude of 0.825, find the sign and magnitude of the charge Q
q1. at one point in a pipeline waters speed is 3.30 ms and the gauge pressure is 4.00times104 pa. find out the gauge
A tennis ball collides with an identical ball at rest. The collision occurs in such a way that one-fourth the initial kinetic energy is lost in deformation of the balls. The outgoing balls go away the impact point making equal angles θ with respect t..
My professor today stated that if a ball was to fall a certain height, then the work done by gravity on the ball would equal the work done by the ball's equal and opposite gravitational pull. By W=F*d, this means that the earth must travel the ..
A disk of radius has a total charge uniformly distributed over its surface. The disk has negligible thickness and lies in the xy plane. What is the electric potential V (z) on z axis as a function of z, for z>0.
