How much energy would be required to break a helium nucleus into its constituents, two protons and two neutrons? The rest masses of a proton (including an electron), a neutron, and neutral helium are, respectively, 1.00783 u, 1.00867 u, and 4.00260 u. (This energy difference is called the total binding energy of the 42He nucleus.)
What is the acceleration of a 747 jumbo jet, mass 31,000 kg, in takeoff when the thrust for each of its four engines is 28,000 N?
What should be the spring constant of a spring designed to bring a 1400 car to rest from a speed of 95 so that the occupants undergo a maximum acceleration of 5.
define the speed of the particle when the string is parallel to the electric field.
A proton is moving in an uniform electric field of part (a). At point A, the velocity of the proton is 1.90 X 104 m/s, east. What is the speed of proton at point B.
The ball is pulled to one side and released to swing as a pendulum, reaching a speed of 5.8 m/s as it passes through the lowest point. Illustrate what is the tension in the rope at that point?
A man lifts a 20.0-kg bucket of concrete from the ground up to the top of a 20.0-m tall building. How much work was done by the man in lifting the bucket
A sailor strikes the side of his ship just below the surface of the sea. He hears echo of the wave reflected from the ocean floor directly below 9 s later. How deep is the ocean at this point.
Two capacitors (C1=1.00 ?F and C2=2.00 ?F) are charged with Q1=3.00 ?C on the positive plate of capacitor 1 and Q2=3.00 ?C on the positive plate of capacitor 2, the total charge on the positive plate of capacitor 1
A 80 kg person sits on a 4 kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.3 cm in diameter. Find the pressure in pascals exerted on the floor by each leg of the chair, assuming the weight is evenly distributed.
