All metals are solid at (our) living temperatures except for mercury which is a liquid. Metals are shiny for a while at least when properly finished. Metals are good conductors of both heat and electricity. This is due to the excess electrons in their valence clouds that facilitate energy transfer.What are 5 characteristics of metal?
Metals are lustrous, malleable, ductile, good conductors of heat and electricity
Silver conducts electricity better than any other metal.
Brass is an alloy made from zinc and copper.
Pure gold is too soft for many things so most gold is combined with other metals to make it stronger. ...
World time periods are often listed by the metal used.
Advantages
Fossil fuels are easy to find beneath the earths surface , fossil fuels has unlimited potential, and fossil fuels are very cost effective, especially coal.
Disadvantages
Burning fossil fuels can cause greenhouse effect which is harming the environment and mining fossil fuels may also endanger the lives of animals.
Answer:
P.E.=29.4Nm
Explanation:
given data
m=1kg
h=3m
g=9.8m/s²
to find
gravitational potential energy=P.E.=?
solution
P.E.=mgh
PUTTING VALUES
P.E.=1kg×9.8m/s²×3m
P.E.=29.4Nm
Answer:
ew so the difference is.. Pollination and Fertilization occur in plants during sexual reproduction.
the difference is Pollination occurs from anthers of stamens to stigma of the ovary and It is a physical process.
fertilizateion is It is the fusion of female and male gametes and It is a genetic and biochemical process.
Explanation:
this was so hard to write out
Coulomb's law states<span> that: The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them.
