A cue ball (mass = 0.160 kg) is at rest on a frictionless pool table. The ball is hit dead center by a pool stick which applies an impulse of +1.90 N s to the ball. The ball then slides along the tabl
A 0.195 kg projectile is fired with a velocity of +715 m/s at a 2.00 kg wooden block that rests on a frictionless table. The velocity of the block, immediately after the projectile passes through it,

(This chapter is on Electric Potential) Four point charges are located at the corners of a square that is 8.0cm on a side. The charges, going in rotation around the square, are Q, 2Q, -3Q, and 2Q,
(The chapter is on Electric Potential) In a certain region of space, the electric potential is given by V=y^2+2.5xy-3.5xyz. Determine the electric field vector, E, in this region.
A car travels along a straight stretch of road. It proceeds for 15.4 mi at 51 mi/h, then 28.9 mi at 40 mi/h, and finally 44.5 mi at 32.4 mi/h. What is the car s average velocity during the entire
Can you help with #13 please? Thank you.
A metallic object is given a positive charge by the process of induction. What happens to the object's mass? The mass does not change at all. The mass increases slightly. The mass decrease

Tips for Asking Questions
- Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
- Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price 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
