A Futuristic design for a car is to have a large disk-like flywheel within the car storing kinetic energy. The flywheel has mass 370 kg with a radius of0.50 m and can rotate up to 520 rev/s. Assume all of this stored kinetic energy could be transferred to linear velocity of the 2800 kg car, discover the maximum attainable speed of the car.
The Earth cools off a night more quickly when the weather is clear than when it is cloudy, why? Describe why the temperature of a gas increase when it is adiabatically compressed.
A cylinder with a height of 1.30 and an inside diameter of 0.110 is used to hold propane gas (molar mass 44.1 ) for use in a barbecue. It is initially filled with gas until the gauge pressure reads 1.80×106 and the temperature is 22.0. The temperatur..
A uniform beam having a mass of 60 kg and a length of 2.8 meter isheld in place at its lower end by a pin. Its upper end leansagainst a vertical frictionless making an angle of 40 degrees withthe horizontal. What is the magnitude of the force by t..
A material is formed into a long rod with a square cross section 0.59 cm on each side. What is the resistivity of the material
A rocket is launched at an angle of 52° above the horizontal with an initial speed of 103 m/s. The rocket moves for 3s along its initial line of motion with an acceleration of 32 m/s2. At this time, its engines fail and the rocket proceeds to move..
The capacitance of a capacitor depends on
A 4 kg model rocket is launched, expelling 40.00 g of burned fuel from its exhaust at a speed of 550m/s. What is the velocity of the rocket after fuel has burned? Hint: Ignore the external forces of gravity and air resistance.
After integrating the electric field for the entire rod, why didthe radius go from R^2 to R and why does the product remainnegative?
