b)What is the difference between elastic and inelastic Collison in terms of total momentum and total kinetic energy ?

At a rock concert, a dB meter registered 130 dB when placed 2.2 m in front of a loudspeaker on the stage.

a. What was the power output of the speaker, assuming uniform spherical spreading of the sound and neglecting absorption in the air?

b. How far away would the sound level be a somewhat reasonable 95 dB ? answer with units

A light source emits a photon during a time interval of 4.87 multiply.gif 10-8 s. a) Find the minimum uncertainty in the photon's energy. b) Find the minimum frequency bandwidth of the light.

A generator with an rms voltage of 130 V is connected in series to a resistor 3.65 kΩ and a capacitor 3.00 μF .

1. At what frequency must this circuit be operated for the current to lead the voltage by 29.0 ∘? (Answer Hz)

2. Using the frequency found in part A, find the average power consumed by this circuit. (Answer in W)

A 1.6-m wire is wound into a coil with a radius of 3.2 cm.

1.

If this coil is rotated at 94 rpm in a 7.2×10⁻²-T magnetic field, what is its maximum emf?

Express your answer using two significant figures.(In mV)

(i) Find the magnitude of magnetic field inside a long, ideal solenoid of length L, with N turns and carrying current i. Demonstrate your knowledge of Ampere’s Law by constructing any relevant Amperian loop and integrating along its length. (ii) Two long solenoids that are coaxial, each carry current i, but in opposite directions. The inner solenoid with radius a has n1 turns per unit length, while the outer solenoid with radius b has n2 turns per unit length. Now apply the magnetic field expression you just derived to find the magnetic field inside the inner solenoid.

The Physics Girl drops a Spalding Hi-Bounce ball ON TOP of a Basketball from1 m until the basketball with the Spalding on top of it hits the ground. The Basketball then STAYS still on the ground but the Spalding FLIES UP into the air. The MASS of the Spalding is 0.1 kg and the mass of the Basketball of 1.0 kg.Using ONLY conservation of ENERGY predict how HIGH the Spalding ball flies upward into the air.

Please write all the steps and formulas used clearly. Thanks!

Please answer all parts of the problem

A person takes 15 minute showers in 100°F water using a 2.0 gallon per minute shower head. Ignoring losses, how many cubic feet of natural gas did the shower need if the house has a 40,000 BTU/hour water heater? The incoming water temperature is 50°F. Is it possible for this person to complete this shower without the water temperature dropping?

This is for an electric field mapping lab.

Show that electic field strength is equal to the potential gradient.

In some video games, spacecraft employ ion drives. Write a one page report discussing how an ion drive operates and whether it can efficiently propel a spacecraft. You will be marked on how well you explain scientific principles and the accuracy of your statements. Your report should be understandable by nonscientists.

Answer these and explain your reasoning.

1. How much energy would it take to remove the electron from unexcited hydrogen completely so that it is no longer bound to its proton?

2. Suppose a hydrogen atom in the n=3 state emitted light by decaying into the n=2 state. What color would that light be seen as? What about one starting at n=4 and ending in n=2? Can a hydrogen atom emit infrared light and end up in the n=2 state?

3.   If you can see light with wavelengths as short as 385 nm, how many lines of the Balmer series might you be able to see by eye with a bright light source and a spectrometer to make a spectrum?

4. Suppose that you could measure accurately the wavelengths of the first two lines of the Balmer series. How could you use those measurements to predict the wavelength of the first line of the Paschen series?

This is the method by which we can find the energy levels of atoms experimentally.

I have tried to answer the following questions. Please let me know if I missed one and why.

1) A light car and a heavy car are headed toward each other from opposite directions at the same speed. The ground is level. Which of the two will be harder to stop?

the heavier car

2)

The two cars move together in the direction of the larger car

3) You are standing on a skateboard on a level surface. Someone throws a ball to you along the direction the skateboard is pointing, and you catch it. In what direction do you move after catching the ball?

away from the ball's thrower

4) You are moving on a skateboard at constant speed towards a ball suspended from a very fine thread. When you reach the ball, you grab it and the thread breaks. What happens to your speed?

5)

It is about the same

6) You stand on a skateboard in the road with your board facing east. An 18-wheel truck from the west impacts with you without braking. How is the truck's speed affected by you?

The truck's speed is slightly less

7) Two trains of equal mass on the same track both travel east. Train A is in the lead and is moving quite slow. Train B is behind, but moving very quickly. When Train B catches Train A they stick, what do you think will happen?

They will move faster than train A but slower than B

A glass with a square cross section when viewed directly from above is filled with water. The glass is 8.0 cm wide on each side and is 17.6 cm high. (a) Find the net horizontal force exerted by the water on each side. (b) Find the net horizontal force exerted by the water on all four walls of the glass. (c) Find the net force exerted by the water on the bottom of the glass.

The thin uniform rod in the figure has length 5.0 m and can pivot about a horizontal, frictionless pin through one end. It is released from rest at angle θ = 50° above the horizontal. Use the principle of conservation of energy to determine the angular speed of the rod as it passes through the horizontal position. Assume free-fall acceleration to be equal to 9.83 m/s2.
