cation
anion is negatively charged, so more electrons then protons,
cation is positively charged, so more protons thatn electrons
Answer:
It would be a square and 2d
Explanation:
Sound is an example of a longitudinal wave.
Answer:
Explanation:
The process is isothermic, as P V = constant .
work done = 2.303 n RT log P₁ / P₂
= 2.303 x 5 / 29 x 8.3 x 303 log 2 / 1 kJ
= 300.5k J
This energy in work done by the gas will come fro heat supplied as internal energy is constant due to constant temperature.
heat supplied = 300.5k J
specific volume is volume per unit mass
v / m
pv = n RT
pv = m / M RT
v / m = RT / p M
specific volume = RT / p M
option B is correct.
A, b and d
Competition for fix resources of course increases the
energy expenditure needed to gather those resources and leaves less for a
given population. A lower amount of sunlight or water also contributes
to decreased energy which lowers growth. Finally, small borders limit
growth in that population density can only go so high before the death
rate increases beyond the birth rate.
