oton speed gold nucleus (m = 3.27 x 10-25 kg). The proton is absorbed by the gold nucleus, thereby converting it into a mercury nucleus. What is the speed vf of the mercury nucleus immediately af- ter the collision? (Note: the proton must be treated rela- tivistically in this problem, but it turns out that the mercury nucleus is traveling slowly enough so that it needn't be treated relativistically.)

Please include explanations and work for the problems. Please write it out to make it easy to understand.

Show the complete solution. Please make sure that your handwritten is readable. Thank you.

select one perpetual motion machines,and provide description of it. Did it work?

Would like step by step solutions with formulas and therefore statements

Stuck need help! Problem is attached. please view attachment before answering.  Really struggling with this concept. Please explain so I can better understand ! Thank you so much

Answer the question below. Use the rubric in the materials for help if needed.Find the gravitational potential energy of a 30 kg box containing books that is lifted to a shelf 3 m high. Show your work for this calculation. Describe two ways the potential energy of this box could be changed. Use details to support your answer.

7. The cart, in the diagram below, travels .80 m down the ramp with uniform acceleration in 1.5 seconds. The initial velocity(v.) is 0 m/s. You must show work. Determine the following. If answer requires a calculation, you must show work. The initial velocity(v.) is 0 m/s. a. Average Velocity b. Acceleration c. The dots in the strips below represent the position of the cart as it rolls down the .80- meter-long ramp. The time intervals between the dots are equal. Which of the strips best represents the motion of the cart down the ramp? Justify your choice. d. Which two strips represent an object moving at constant velocity? Justify your answer.

Can you please solve this question and all of the sub problems and show all of the work
