Question

A proton is fired from far away toward the nucleus
of a mercury atom. Mercury is element number 80,
and the diameter of the nucleus is 14.0 fm.
Part A
If the proton is fired at a speed of 3.2x107 m/s, what is its closest approach to the surface of the nucleus? Assume the
nucleus remains at rest.

High-intensity focused ultrasound (HIFU) is one treatment for certain types of cancer. During the procedure, a narrow beam of high-intensity ultrasound is focused on the tumor, raising its temperature to nearly 90°C and killing it. A range of frequencies and intensities can be used, but in one treatment a beam of frequency 4.40 MHz produced an intensity of 1425.0 W/cm. The energy was delivered in short pulses for a total time of 3.40 s over an area measuring 1.80 mm by 5.40 mm. The speed of sound in the soft tissue was 1580 m/s, and the density of that tissue was 1509.0 kg/m?.

A uniform electric field is created by two horizontal parallel plate electrodes of length 10 cm separated by a vertical distance d = 5 cm and held at a potential difference V = 250V. A beam of electrons is introduced between the two plates with a horizontal velocity v = 5 x 106 m/s. What is the deflection distance towards the positive plate when the electron beam leaves the electric field? Select one: a. 5.0 cm b. 3.5 cm c. 1.76 cm d. 8.8 mm
My physics class has turned to online due to the COVID-19 and I am having trouble with some of the word problems my teacher gave me to work on. She presented me with: I am contemplating a career change. If I had 500g of stolen gold jewelry, how much energy would I have to add to it to melt it (so that it was not longer recognizable)? Pretend that it is pure gold. Would you be able to show me how to accomplish this problem so I can see the steps? Thank you for your time. John Payton
Have you ever chewed on a wintergreen mint in front of a mirror in the dark? If you have, you may have noticed some sparks of light coming out of your mouth as you chewed on the candy; and, without knowing it, you have experienced a physical phenomenon called triboluminescence. In this problem you will analyze some of the key elements of triboluminescence in wintergreen candies. Part C Image that the radiation emitted by the nitrogen at a frequency of 8.88×1014 Hz is absorbed by an electron in a molecule of methyl salicylate. As a result, the electron in the wintergreen oil molecule jumps to an excited state. Before returning to its ground state, the electron drops an intermediate energy level, releasing two-thirds of the energy previously absorbed and emitting a photon. What is the wavelength Xw of the photon emitted by the wintergreen oil molecule? Express your answer in nanometers to three significant figures. ► View Available Hint(s) Aw= Submit [-] ΑΣΦ ? nm
A thin spherical shell with radius R₁ = 4.00 cm is concentric with a larger thin spherical shell with radius R2 = 6.00 cm. Both shells are made of insulating material. The smaller shell has charge q₁ = +6.00 nC distributed uniformly over its surface, and the larger shell has charge q2 = - 9.00 nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells. - For related problemsolving tips and strategies, you may want to view a Video Tutor Solution of Potential vsurface and field magnitude esurface at the surface. ▶ Part A Part B
