Aproton and a neutron of masses (given in data) are confin deep square-well potential with l- 10 femto meters a ve ) sketch a diagram to show the allowed energy levels of the both particles inside the well. (ii) estimate their ground-state energies of each. fii) define briefly and provide examples of nuclear reactions known as fission" and "fusion". what makes those reactions plausible?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

What accounts for an increase in the temperature of a gas that is kept at constant volume? a. energy has been removed as heat from the gas. b. energy has been added as heat to the gas. c. energy has been removed as work done by the gas. d. energy has been added as work done by the gas.

Why is a noble gas different from other elements?
