Define A Gamma Ray .....---_---__☘️​
MrRa [10]

Answer:

gamma ray, or gamma radiation (symbol γ or {\displaystyle \gamma } \gamma ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation gamma rays based on their relatively strong penetration of matter; in 1900 he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power.

The energy stored in a wooden log transforms when the log is burned. Which of the following explanations BEST describes how the
Makovka662 [10]

Answer:

D. the amount of chemical energy equals the amount of heat and light energy.

Explanation:

Given that the first law of thermodynamics affirmed that energy is neither created nor destroyed however, it can be transformed from one form to another. In other words, while, during the transformation of energy, no energy is lost, the input energy is also equal to output energy.

Hence, the chemical energy stored in the log is EQUAL to the heat and light energy produced by burning.

What is the process called in which water vapor and carbon dioxide retain heat?
saw5 [17]

The process in which water vapour and carbon dioxide traps heat is called the “greenhouse effect”.

 

The greenhouse effect is a natural phenomenon which occurs every day. To illustrate an example of this natural phenomenon, d<span>uring the day the Sun shines through the atmosphere. Earth's surface warms up because of the sunlight. Meanwhile at night in the absence of the sunlight, Earth's surface cools back and releasing the heat back into the air. However some of the heat is retained by the greenhouse gases (such as carbon dioxide and water vapour) in the atmosphere. This process what keeps our planet Earth warm and cozy at an average temperature of 16°C.</span>
