A large tub rests at the edge of a table 1m high. The tub is full, and is 2m tall with an area of 1000cm^2. If a hole 1cm^2 is made in its side 2m above the bottom:
a.) Determine the speed of the water as it leaves the side?
b.) How far along the floor it will reach when it hits the ground?
a bar magnet is dropped through a loop of wire, what is the direction of the current at the instant it is in the middle
Blocks with masses of 2 , 4 , and 6 are lined up in a row on the frictionless table. All three are pushed forward by a 56 force applied to the 2 block. How much force does the 4 block exert on the 6 block.
A nanowire is a (nearly) one-dimensional structure with a diameter on the order of a few nanometers.
Indicate the negative x direction by including a negative sign in the answer, but omit a sign for the positive x direction.
A 1.0-kg block is pushed up a rough 22° inclined plane by a force of 7.0 N acting parallel to the incline. Determine the magnitude of the force of friction acting on the block
What is the coefficient of static friction among the coin and the turntable? Express your answer using two significant figures.
Cheetahs, fastest of the great cats, can reach 45 in 2 starting from rest. Assume that they have constant acceleration throughout that time, find their acceleration (in (a) and (b) ) and the distance (in (c) and (d) ) Q2. They travel during that t..
Two spheres of mass m and a third sphere of mass M form an equilateral triangle, and a fourth sphere of mass mB is at center of the triangle.
What is the total negative charge, in coulombs, of all the electrons in a small 1.05{\rm g} sphere of carbon? One mole of C is 12.0{\rm g} , and each atom contains 6 protons and 6 electrons.
find the magnitude of the baseballs momentum.
Object A is metallic and electrically neutral. It is charged by induction so that it acquires a charge of -2.86E-6 C. Object B is identical to object A and is also electrically neutral.
