The pressure gauge on a tank registers the gauge pressure, which is the difference between the interior pressure and exterior pressure. When the tank is full of oxygen (O2), it contains 9.00 kg of the gas at a gauge pressure of 37.0 atm. Determine the mass of oxygen that has been withdrawn from the tank when the pressure reading is 22.4 atm. Assume the temperature of the tank remains constant.
A string under a tension of 49.0 N is used to whirl a rock in a horizontal circle of radius 2.40 m at a speed of 20.8 m/s on a frictionless surface, What is the breaking strength, in newtons, of the string
A top is a toy that is made to spin on its pointed end by pulling on a string wrapped around the body of the top. What is the final angular velocity of the top when the string is completely unwound
A pendulum consists of a 4.98kg mass on the end of a 0.873 m string. The mass is pulled aside so the string makes an initial angle with the vertical of 12.5o. The mass is then released with initial speed of 2.10m/s upward and perpendicular to the rop..
