Light from a monochromatic source shines through a double slit onto a screen 5.0 m away. The slits are 0.18 mm apart. The dark bands on the screen are measured to be 1.7 cm apart. What is the wavelength of the incident light?
Suppose that the air bubble is always in thermal equilibrium with the surrounding water.
A steel cable has a cross-sectional area 3.44 × 10-3 m2 and is kept under a tension of 1.53 × 104 N. The density of steel is 7860 kg/m3. Note that this value is not the linear density of the cable. At what speed does a transverse wave move along t..
A parallel-plate capacitor has an area of 2.0cm^2, and the plates are separated by 2mm.
Pretend a person can walk only at a certain pace no faster, no slower. If you time her uninterrupted walk across a room of known length, you can compute her walking speed.
An object has a kinetic energy of 303 J and the momentum of magnitude 22.9 kg·m/s. Find the speed and the mass of the object.
A neutral conductor completely encloses a hole inside of it. you observe that the outer surface of this conductor carries a charge of -12 microC. A) can you conclude that there is a charge inside the hole? b) how much charge is on the inner surfac..
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
illustrate what is the magnitude of the acceleration of the box and hanging mass.
An archer puts a 0.34 kg arrow to the bowstring. An average force of 209 N is exerted to draw the string back 1.3 m. Unless otherwise directed, assume that air resistance is negligible. plan energy bar graphs to solve the problem.
We are not normally aware of the gravitational or electric force between two ordinary objects. What is the reason in each case? Give an example where we are aware of each one and why.
A 12.0 resistor, 10.0 mH inductor, and a 50.0 µF capacitor are connected in series to a 55.0 V (rms) source having variable frequency. Find out the energy delivered to the circuit during one period if the operating frequency is twice the resonance..
