Answer:
Gamma rays
Explanation:
The penetrating power of gamma rays is maximum as compared to beta and alpha rays. Gamma rays are nothing but the photons i.e. the packets of energy. Their energy range lies from kilo electron volts to 8 mega electron volts. It is emitted during the decay of many radioactive isotopes, such as U-238 and I-131. A large amount of energy is produced in decay of uranium 238.
Hence, the correct option is " gamma rays ".
Answer:
electromagnetic induction
Explanation:
Water or working fluid is heated (or used directly incase of geothermal dry steam power plants), and then sent through a steam turbine where the thermal energy (heat) is converted to electricity with a generator through a phenomenon called electromagnetic induction.
Answer:
About 3.88 meters per second
Explanation:
14km= 14,000m
14,000m per hour
so 14,000 ÷ 60= 233.33 meters per minute
233.33÷60=3.88 meters per second
ITS C
This element tends to lose 2 electrons to become a 2+ ion, is the correct statement regarding the element calcium. Calcium has 2 electrons in its outer shell and it is easier to lose them than it is to gain enough to become stable. When stable it has 2 more protons than electrons forming a 2+ ion.
