Answer:
its an insulator
Explanation:
they block electricity from passing
Answer:
Air pressure is the weight of air particles pressing down on the surface of the earth. Air pressure may be high or low. A high pressure system is associated with cooler temperatures and clear skies. A low pressure system is associated with warmer weather, storms or precipitation.
Barometer Measures: Air Pressure
Rain Gauge Measures: Precipitation
They can decay through one of three ways:
alpha decay
beta decay and
gamma decay
ALPHA- particle with two neutrons and two protons is ejected from the nucleus of the radioactive atom. this particle released is called an alpha particle. Only occurs with heavy metals.
BETA- pretty much when a proton is transformed into a neutron, or vise versa. in a beta minus decay, the nuetron decays into a proton and in a beta plus decay, a proton decays into a neutron
GAMMA- the nucleus changes from a high energy state to a low energy state by releasing electromagnetic radiation (photons). the number of protons and neutrons stay the same during this reaction therefore the element is still the same.
