Carbon-14 atom have 6 protons plus 8 neutrons.
Explanation
Carbon-12 and Carbon-14 are examples of isotopes of carbon that have huge applications in the field of science.
Isotopes are those elements who have equal number of protons and electrons whereas their neutrons differ.
Therefore isotopes have same atomic number, as atomic number depends on number of protons or number of electrons whereas number of neutrons do not have a role in atomic number.
But mass numbers of isotopes are different as mass numbers depend on the number of protons and number of electrons.
No. Any amount of gas always expands to completely fill
whatever container it's in.
So, as you take oxygen out of the tank, the pressure of what's
left in the tank certainly becomes less and less, but whatever is
left in the tank always expands and fills the whole tank.
(And then, eventually, when the pressure inside the tank drops
to equal the pressure outside it (atmospheric pressure), you could
cut off the whole top of the tank and nothing more would come out.)
SCUBA divers regularly talk about having a 'full tank', and 'half a tank',
and maybe a 'quarter tank'. But that refers to the amount of time that
the tank can still deliver air to them under water. It's not the amount
of volume inside the tank that's full or empty. The inside of the tank
is always full.
Think about it this way: ==> There's no way to take half of the air
out of a balloon, leaving it half empty and still inflated. Doesn't happen.
Answer:
From -15⁰ to 0⁰
H=mc¶
where H= heat absorbed or evolved
m=mass involved
c=specific heat capacity
¶=change in temperature
H=mc¶
Given that,
Acceleration due to gravity = g
Time period :
Time period is defined as,
Where, l = length of pendulum
g = acceleration due to gravity
We need to calculate the value of g
Using formula of time period
Where, T = time period
l = length of pendulum
Hence, The value of g is
Um this doesn't make since to me since you did not clearly state your awnser
