In this post, we will work our way through the HSC Physics Paper and give you the solutions to all of the questions. If the energy is insufficient to eject the electron, it will relax back down to a low energy before absorbing another photon.

This is less than the minimum energy required for electrons to absorb in order to be ejected from the surface so electrons will not be ejected. The current is clockwise so force is into the page at BC by Right Hand Palm Rule, so torque is clockwise as viewed from the bottom of the page.

To validate theories in physics, independent valid experiments must be performed to test the different predictions made by the theory. If the results of different independent experiments match the predictions of the theory and no valid experiments contradict the predictions then the theory becomes validated.

Special Relativity is based on two principles and makes several predictions. The two principles are that 1 the laws of physics are the same in all inertial frames. Principle 1 has been validated since before special relativity, in that experiments done in inertial frames give the same result as if they were at rest.

Principle 2 was validated by many experiments measuring the speed of light, and particularly by the Michelson—Morley experiments where there was no change in the speed of light due to the motion of the Earth. The predictions of special relativity include time dilation, length contraction, relativity of simultaneity, mass dilation and the speed limit of massive objects.

Time dilation has been validated by comparing moving atomic clocks to stationary ones, and by needing to adjust GPS satellite times. Mass dilation is witnessed in particle accelerators where the kinetic energy of particles increases even though their velocities never reach c. The appearance of muons at the surface of the earth, created by cosmic rays in the upper atmosphere, are incompatible with classical physics but explained by length contraction and time dilation.

Observations from many independent sources agree with a range of predictions of special relativity and no valid observations disagree, so this theory is validated. The object must therefore be provided with enough kinetic energy on the planet providing it with escape velocity v esc at radius r planet to convert to potential energy at an infinite distance away. Its total energy must be zero:. The Braggs discovered and developed X-ray crystallography.

A collimated beam of X-rays are fired at a material. They diffract off the cations, producing an X-ray diffraction pattern captured by photographic film. The regular array of maxima in the diffraction pattern indicates the regular lattice crystal lattice structure of the material, with spacing of the maxima relating to lattice spacing and the shape of the pattern relating to shape of the crystal lattice.

This was the first method of directly showing that some materials have a crystal lattice structure consisting of a repeating regular array of cations, allowing the dimensions of the lattice to be measured. Doping pure silicon with boron will produce a p-type doped semiconductor. The valence of boron is 3, so it only forms 3 bonds with nearby silicon atoms. An empty acceptor level forms near the valence band of the silicon that can easily accept valence electrons at room temperature.

This results in many mobile holes in the valence band of the silicon at room temperature. This increases the number of mobile charge carriers and significantly improves conductivity. Maglev trains require strong magnetic force but low weight in order to be levitated. The magnets need to be compact in order to fit on board and be cooled below Tc more easily. Superconductors achieve strong field with low weight and size. This results in large g-force on the craft that can destroy the craft or directly injure the crew, and converts KE into heat too rapidly leading to intense heating which could cause the craft to burn up.

The consequence is destruction of the craft and crew. A spacecraft converts large gravitational potential energy and kinetic energy to heat via friction and shock heating of the gases around the craft. This slows the craft down so that it can safely land, but causes heating to the craft which must be kept within safe limits. This also heats the air around the craft to K so it visibly glows, according to the graph.

This radiation dissipates some of the heat to surrounding regions but the glow is accompanied by ionisation blackout whereby the craft cannot send or receive radio signals to the control station.Physics is one of the oldest academic disciplines, perhaps the oldest through the inclusion of astronomy. In the last two millennia, physics was a part of natural philosophy, chemistry, certain branches of mathematics and biology, but during the scientific revolution in the 17th century, the natural sciences emerged as unique in its own right research programs.

Physics intersects with many interdisciplinary areas of research, such as Biophysics and quantum chemistry, and physics limits are not rigidly defined. New ideas in physics often explain the fundamentals of other sciences mechanisms, to open new avenues of research in areas such as mathematics and philosophy.

This has been a great cell phone service and very affordable for my family. My two sons are in college and they have Tello, so with that, thank you for the awesome service and for taking care of us!!!. Their customer service is outstanding, if you ever have to call them a real person answers the phone and makes sure you are satisfied before you hang up.

Love love love this company My phone recently suffered water damage, so I bought a new one and tried to switch service over. The website said I needed a new SIM card, but I didn't believe it because both phones take nano Sprint SIMs. I contacted support via chat, and they were able to explain not only that the website was correct, but that different model phones require different SKUs of Sprint SIM card to operate on the Sprint network.

Support was very fast and polite, and the prices can't be beaten for a light cell phone user like me. I highly recommend this company.

Please ask your Tello representative about any limitations. The RAV4 has made astonishing improvements to the RAV4 since the early 2000s when my brother-in-law owned one. Stylish, modern, high tech and smooth ride. It was too good to pass up. This is my fourth Toyota and Toyota has consistently proved to be reliable vehicles. Report Abuse Read All Reviews My New RAV4 I bought my new 2017 RAV4 SE the end of December 2016.

I sold my 2015 Mercedes-Benz C300 4 Matic and wanted an SUV because I retired and want to play in a band and neeed room for my drums. I chose Toyota because they are so reliable. I love this SUV but I'm sorry that I didn't get the Hybrid because the gas mileage is NOT good (very disappointed).

The ride and comfort is excellent and the visability is great. The blind spot alert could have been better, it lights up yellow rather than bright Red and doesn't beep when a car is in the blind spot and you have the blinker on.

All in all it's a great SUV except for the gas mileage. Report Abuse Read All Reviews 2017 RAV4 Light Years Ahead of Older Model We compared both the new 2017 Mazda CX-5 and the RAV4 and while both are excellent compact SUVs, my wife preferred the lower dashboard and simpler console of the RAV4, so that's how we went.And it's only 28 days. It's worth a try right. Now, I've got a LONG long way to go until I reach my goal but its just exciting to see that what I'm doing is actually working.

The left is me 5-6 weeks ago and the right is me today. Hopefully in another few weeks I'll have even more exciting changes. AngelaHere are my before and after pictures from my 28-day SkinnyMint teatox. The reason I did the teatox was to see if it would help me. I've tried everything under the sun and this really helped, as you can see.

Of course this was paired with a healthy diet and exercise and if it wasn't for a few birthday treats last week, I think the results would have been even better. I highly recommend it. Once you start seeing improvement in yourself, it makes you even more determined to work for what you want. CANT WAIT TO START MY SECOND BATCH AGAIN Camille Amber JohnsonI've completed the 28 day SkinnyMint Teatox and just posted a review on my channel.

Over the past month I've managed to get closer to my fitness goals for the summer :) Watch the video for before and after and more details. The nice thing about this is that I didn't have to go on any specific diets, change my eating habits, or do any fancy workouts. I just drank my tea in the morning and every other night. I know my body still isn't the best but it's a good start to how I want my body to look.

Christa CorbinI heard about Skinny Mint from the web. I was looking for a new detox tea because mine was just causing me to run to the bathroom every hour or so when I drank it. I looked through their Real Results page and I just knew I had to try it. I've always lived a healthy life until I was diagnosed with Arthritis and my daily exercise and yoga became less frequent.

I decided to turn my life around because I didn't like how my body looked anymore and I knew I needed and wanted to live a healthier life once again. Not only did the Morning Boost give me energy it taste and smells just like berries. It helped soothe my unwanted cramping pains and discomfort that comes along with Mother Nature.

It also helped me fall asleep too. I'm less bloated and my skin has been clearing up miraculously.
