Answer:
a=1.8 m/s^2
Explanation:
F=ma
So
a=F/m
Where F=1800 N, m=1000 kg
a=1800/1000
a=1.8m/s^2
What gas? Gas is an invisible form so I don't see how it would have a "defined structure".
Answer:
balanced forces happen when two forces acting on an object are similar in size but act in opposite directions.
Example:
tug-of-war is a perfect example. If the people on each side of the rope are pulling with the same strength, but in the opposite direction, the forces are balanced. The result is no motion.
Hope this helps please mark me brainliest!
God Bless!
The process that produces the energy radiated by stars is nuclear fusion in the core.
For a star on the main sequence, it's the fusion of hydrogen nuclei into helium.
<span>The Solar electricity source of
energy comes from the sun’s rays. It is more often in the form of a panel known
as the solar panel. It has a photovoltaic system that generates and supplies
energy in commercial and residential areas. Even though numerous countries are
using this type of electricity to save electric-induced power, it is not used
for a number of reasons. One is that 1 panel with a size of 6 by 10 solar cells
is expensive. There are countries who cannot afford to buy them. Two, it
requires a larger area to place the panel. Three, the efficiency is low. The smaller
the panel is, the lower its efficiency and therefore produces lesser power to
generate a specific area. </span>
