Tamoxifen which comes from the pacific yew tree treats cancer, it does not stop it but helps prevent cancer
The word abstract means apart from concrete reality or existence.
Because no conductor is a perfect conductor of electrical energy (apart from superconductors). This means that some electrical energy is converted to kinetic energy as the electrons vibrate/move (depending on your idea of how electrical force is moved) and this kinetic energy is emitted as heat.
Things that can be separated by physical means are mixtures. There are two types of mixtures: homogeneous and heterogeneous. In a heterogeneous mixture, you can see the different components that make up the mixture. You can't see the components in a homogeneous mixture. Things that can only be separated by chemical means are compounds.
The Earth is (As of May 2000) thought to be approximately 5.972 sextillion (5,972,000,000,000,000,000,000) metric tons. A metric ton is a thousand kilograms, or 2,204.62 pounds. Approximately 6,000,000,000,000,000,000,000,000 (6E+24) kilograms.
It means to draw a conclusion.
Radioactivity is the disintegration of the substance by its own. This means disintegration depends only on one reactant concentration i.e.,on itself. So this is a first order reaction.
It is the grade of concrete which indicates the strength of concrete after 28 days curing. M #) means the strength of concrete after 28 days of curing will be 30 N/mm2 .
To 'sanctify' means to set apart as sacred.
it means to set or place apart.
A cloud chamber is an instrument that detects radioactivity by condensing gases to create visible vapor trails from ionizing radiation particles. These trails make the presence of radioactivity visible and can help identify the type and energy of the particles.
An unstable atomic nucleus breaks apart, and converts into another atom. Some radiation will also be emitted.Each type of atom (each isotope) has a characteristic half-life; for example, Tritium (3H - a hydrogen atom consisting of one proton and two neutrons) has a half-life of about 19 years. This means that if you have a large number of Tritium atoms, after 19 years half of them will have broken apart - changed into something else. However, you can't predict when an individual atom will break apart - except that there is a high probability that it will happen after a few times the half-life, at the most.
No radioactivity doesn't mean emitting radio waves. It means emmission of alpha & beta particle and gamma rays
The magma is in the mantle, the layer under the crust. There is a convection current caused by radioactivity in the inner core which causes the plates to move. Therefore the constructive plates move apart which means magma can rise up. It'll then solidify and this is what makes volcanoes. Hence CONSTRUCTive.
If there is no radioactivity, it implies that no radioactive decay or nuclear processes are occurring. While this may be positive from a safety perspective, it also means that certain medical treatments, radiation therapy, and certain industrial processes that rely on radioactivity would not be possible. Additionally, our understanding of nuclear physics and certain natural phenomena would be limited.
It means to be set apart.
Fragment.
