making them incredibly dense. This means that their gravitational pull is immense, for example, on the surface of a neutron star gravity is around 1 billion times stronger than its pull on Earth. This makes
Radiation therapy uses x-rays or gamma rays to treat cancer. Radiation kills cancer cells and may stop the cancer from spreading. It may be given alone or with chemotherapy. A bone marrow transplant is a procedure to replace your bone marrow with healthy marrow. You are usually given bone ...
of a stronger and more fundamental force which binds together quarks in protons and neutrons." This "side effect" is called the "residual strong force" or the "nuclear force," and it is what holds atomic nuclei together in spite of the repulsive electromagnetic force between the positively cha...
astronomers have hypothesized that the universe must contain more matter than we can see because the gravitational forces that seem to be at play in the universe simply appear stronger than the visible matter alone would account for.
Since violet light has a higher frequency than red, we say that it has more energy. If you go all the way out on the electromagnetic spectrum, you will see that gamma rays are the most energetic. This should come as no surprise since it is commonly known that gamma rays have enough ...
A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
Solar nails are a type of artificial nail that is applied over natural nails. They are made from a combination of acrylic and gel and are available in a variety of colors and styles. Solar nails are designed to last longer than traditional artificial nai
Ultraviolet rays have poor penetration, so the effect is poor, but it is relatively safe and can be used for small-area disinfection. X-rays and gamma rays have much stronger penetrating power, so they are more effective for large-scale sterilization. However, they are more dangerous, so ...
Corticosteroid creams, solutions, gels, foams, and ointmentscan quickly relieve itching and reduce inflammation. They come in various strengths, from mild over-the-counter (OTC) treatments to stronger prescription medicines. OTC hydrocortisone is often the first thing doctors recommend to treat mild ...
Knee pain often happens the when the outer muscles of the thigh are stronger than those in the mid-thigh (causing the kneecap to be pulled “off track”), so your doctor will pay particular attention to the vastus medialis, a muscle in your mid-thigh that extends to the knee. You ...
