A 2000 kg car is slowed down uniformly from 22.0 m/s to 6.00 m/s in 4.20 s. (a) What average total force acted on the car during that time? N (b) How far did the car travel during that time?

A 54.4 kg ice skater is moving at 4.04 m/s when she grabs the loose end of a rope, the opposite end of which is tied to a pole. She then moves in a circle of radius 0.801 m around the pole. (a) Deter

The rms speed of an oxygen molecule (O2) in a container of oxygen gas is 542 m/s. What is the temperature of the gas? K

A person with a mass of 76 kg and a volume of 0.084 m^3 floats quietly in water. The volume of the person above the water is 8.00*10^3 m^3. If an upward force F is applied to the person by a friend,

An ion accelerated through 300.00 V has its potential energy decreased by potential energy of 9.60 1017 J. Calculate the (magnitude of the) charge on the ion. C

Please see the attachment, thankyou...!

A disk has mass 6 kg and outer radius 80 cm with a radial mass distribution (which may not be uniform) so that its moment of inertia is 9 m R2 . The disk is rotating at angular 10 speed 3 rad/s arou

A thin uniform cylindrical turntable of ra dius 2.9 m and mass 17 kg rotates in a hori zontal plane with an initial angular speed of 7.5 rad/s. The turntable bearing is friction less. A clump of cl

Consider a thin 16 m rod pivoted at one end. A uniform density spherical object (whose mass is 9 kg and radius is 4 m) is attached to the free end of the rod and the moment of inertia of the rod about

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.
Sample Questions
 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?
1. Can you show me step by step how to solve this problem?:
 A spherical balloon is made from a material whose mass is 3.00kg. The thickness of the material is negligible compared to the 1.5m radius of the balloon. The balloon is filled with helium (He) at a temperature of 305degrees K and just floats in the air, neither rising nor falling. The density of the surrounding air is 1.19kg/m^3. Find the absolute pressure of the helium gas
2. I do not understand this Ideal Gas Law and Kinetic Theory question. Can you help me set it up?
