A soap film (n = 1.33) is formed in a loop of wire that is mounted vertically is not exactly uniform in thickness because of its weight, but wedge-shaped in cross section. When the film is illuminated...

The glass plates in the figure are separated by a thin round filament. When the top plate is illuminated normally with a light of wavelength 730 nm, the filament lies directly below the twelfth order...

A 100 kg mass is blown apart into a 60 kg piece and a 40 kg piece (you can assume the initial velocity to be zero). After the blast, the two masses are moving apart with a relative velocity (vbf –...

How fast (in m/s) must a 2.7-g ping-pong ball move in order to have the same kinetic energy as a 145 g baseball moving at 35.0 m/s?

a.Find the electric field at a point midway between two charges of +43.9 ✕ 10-9 C and +68.2 ✕ 10-9 C separated by a distance of 41.4 cm. N/C in a direction towards the +43...

What is the amount of work done by the person climbing the ladder

The center of mass of a person may be determined by an arrangement such as the one shown in the figure below. A light plank rests on two scales separated by a distance of d = 1.80 m and...

it is a physics question. i think figure out how to solve it. 7.5 * 10^-6

Lets say, I know total time of motion. I also know n-distances and velocity during them. So for example I can say that: total time = time1 +time2+time 3, where time1 = distance1/velocity1...

In a dc circuit, where a power supply connected into a circuit containing an amp meter, when you crank up the voltage of the power supply the reading of the amp meter also increases. With the definition...

The horizontal boom supporting the sign is of uniform construction and weighs 50 N. If the sign weighs 150 N, the angle between the force exerted by the hinge on the boom and the boom is approx...

A 4.00 kg object is moving at 5.00 m/s WEST. It strikes a 6.00 kg that is moving WEST at 2.00 m/s. The objects have a one-dimensional elastic collision in the EAST-WEST direction. The velocity of...

A car can round a banked curve at an 84 m radius and a maximum speed of 16 m/s without relying on friction. What is the angle does the car bank when it turns?

An amusement park ride consists of a vertical cylinder that rotates about its axis. The radius of the cylinder is 2.5m and rotates at a constant speed of 15 m/s. What is the minimum coefficient of...

A .25 kg object is attached to a 0.80m string. The object is pulled to a point so that the string makes an angle θ from the vertical. It is then released. At the bottom of the object's path,...

How much work does a supermarket checkout attendant do on a can of soup he pushes 0.650 m horizontally with a force of 4.90 N? Express your answer in joules and kilocalories.

In a downhill ski race, surprisingly, little advantage is gained by getting a running start. (This is because the initial kinetic energy is small compared with the gain in gravitational potential...

A radio controlled ariplane is suspended from a 0.80 m string. The plane revolves in a circle at a constant speed. The angle the string makes from the vertical is 60º. What is the speed of the plane...
