A rectangular fish tank measures 30 cm by 65 cm by 40 cm high.
(a) If the tank is filled with water to a depth of 37 cm, what is the pressure at the bottom due to the water?
(b) What is the total force of the water on the bottom?
A cart of mass M1 = 5.00 kg and initial speed = 4.00 m/s collides head on with a second cart of mass M2 = 3.00 kg at rest. find the speed of M2 after the collision
Calculate the Q-value, recoil energy of the daughter nucleus and the kinetic energy of the alpha particle in the following alpha decays
A wooden raft has a mass of 59 kg. When empty it floats in water (density 1000 kg/m3) with 59 percent of its volume submerged. What mass of sand can be put on raft without it sinking.
A massless spring with spring constant 22.10 N/m hangs vertically. A body of mass 0.280 kg is attached to its free end and then released. Assume that the spring was unstretched before body was released. How far below the initial position does the ..
A total charge of Q is deposited on a solid metal sphere of radius R. This charge distributes itself uniformly over the surface, yielding an electrostatic field E~ perpendicular =(sigma / e0) n^ just outside the sphere and E~ = 0 everywhere insid..
The first puck is deflected 38 below the +x axis and moves off at 0.37 m/s. Find out the speed and direction of the second puck after the collision.
You are asked to design a parallel-plate capacitor having a capacitance of 1 F and a plate separation of 1.00 mm. compute the required surface area of each plate. Is this a realistic size for a capacitor.
Why is it better for some purposes to use a medium size telescope on a mountain instead of a telescope in space?
Two concentric hollow metal spheres have radii r1=1.50E-2 m and and r2=6.80E-2 m. At a point 9.80E-2 m from the center of the spheres, the electric field is directed outward and has a magnitude 2.08E+2 N/C. At a distance 5.80E-2 m from the center,..
A ball is tossed from an upper story window of a building. Compute the height from which the ball is thrown.
A small metal particle passes downward through a fluid medium while being subjected to the attraction of a magnetic field such that its position is observed to be s = (15t3 - 3t) mm, where t is measured in seconds. Determine (a) the particle's dis..
