n m1 = 7.40 g bullet is fired into a m2 = 2.55 kg block that is initially at rest at the edge of a frictionless table of height h = 1.13 m, as seen in the figure below. The bullet remains in the block, and after impact the block lands d = 2.05 m from the bottom of the table. Calculate the...
The motion of the uniform rod AB is guided by small wheels of negligible mass that roll on the surface shown. If the rod is released from rest when theta=0, determine the velocities of A and B when theta=30 degrees.

The field just outside a 2.80 cm radius metal ball is 2.95 102 N/C and points away from the ball. What charge resides on the ball? The total electric flux from a cubical box 30.0 cm on a side is 1.65 103 N m2/C. What charge is enclosed by the box?
why the angular momentum of electron in the s orbit equals zero
A block of mass m = 4.2 kg, moving on a frictionless surface with a speed makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 4.2 block recoils with a speed of In Fig. 9.p1, the mass M is closest to:
The length of a simple pendulum is 0.86 m and the mass of the particle (the "bob") at the end of the cable is 0.12 kg. The pendulum is pulled away from its equilibrium position by an angle of 7.7 and released from rest. Assume that friction can be neglected and that the...
1. A pirate s treasure chest lies 20.0 m below the surface of the ocean. What is the magnitude of the force that acts on the rectangle top that is 0.750 m x 0.425 m? [Note 10**3 is ten raised to the third power or 1000]
A 1290-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 2000-N crate hangs from the far end of the beam

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
1. Can you show me step by step how to solve this problem?:
- The Earth’s rate of rotation is constantly decreasing, causing the day to increase in duration. In the year 2000 the Earth takes about 0.548 s longer to complete 365 revolutions than it did in the year 1900.
- (a) What is the average angular acceleration of the Earth?
- (b) If this average acceleration remains constant, in what year will the Earths rotation come to rest?
2. I do not understand this Ideal Gas Law and Kinetic Theory question. Can you help me set it up?
- A spherical balloon is made from a material whose mass is 3.00-kg. The thickness of the material is negligible compared to the 1.5-m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305-degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19-kg/m^3. Find the absolute pressure of the helium gas
