Electron deflection in an oscilloscope This problem deals with several aspects of an oscilloscope. You have an 17500 volt supply (Vsupply) for accelerating electrons to a speed adequate to make the front phosphor-coated screen glow when the electrons hit it. Once the electron has emerged from...
What is the mass of gasoline (density = 0.680 g/cm^3) in a 100. L tank
A rifle is aimed horizontally at a target 50.0 m away. The bullet hits the target 1.70 cm below the aim point. What was the bullet's flight time? What was the bullet's speed as it left the barrel?
Two 3.0 kg balls are attached to the ends of a thin, massless rod 1 m long. The rod is free to rotate about a horizontal axis through its center. A 100 g putty ball moving at 3.0 m/s drops onto one of the balls and sticks to it. A. What is the angular speed of the system just after the putty...
An arrow leaves a bow at an angle of takeoff of 31 degrees and an initial vertical velocity of 21.3 m/s. How high will it go above the point of release?
A batter hits a pitched ball when the center of the ball is 1.25 m above the ground. The ball leaves the bat at an angle of 45 with the ground. With that launch, the ball should have a horizontal range (returning to the launch level) of 107 m.
Three objects are connected by light strings as shown in Figure P4.62. The string connecting the m1 = 4.50 kg mass and the m2 = 4.60 kg mass passes over a light frictionless pulley. Figure P4.62 (a) Determine the acceleration of each mass.
every force has one and only one pair of forces
in thrill machine rides at amusement parks there can be acceleration of 3g or more.but without head rests acceleration like would not be safe.think why not?
A train is traveling up a 3.5 incline at a speed of 2.50 when the last car breaks free and begins to coast without friction.

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
