If the width of the slit is increased by a factor of two , then the central maxima will get decreased by half.
since , width of the central maxima is inversely proportional to the width of the slit . Which implies if width of the slit get increased then width of the central maxima will get decreased and vice versa.
central maxima = (2 * wavelength * D) / width of the slit
= (2 * lambda * D) / d
if initially width of the slit = d
then, after increasing it by a factor of two it become = 2d
central maxima = (2 * lambda * D) / 2d
= (lambda * D) / d
If the width of the slit is increased by a factor of two , then the central maxima will get decreased by half.

According to the American Heart Association, the broad,
approximate guideline for your MAXIMUM heart rate is:
-- take 220
-- subtract your age
The unit is "beats per minute".
But there are many things that have an effect on this number.
A few of them are:
-- your age
-- your weight
-- any medicines you're taking
-- HOW you measure your heart rate.
If you're planning any REGULAR activity that will play with
your heart rate, you really ought to discuss it with your doctor
before you jump in.
If a new substance suddenly appears that wasn't there originally,
then a chemical change has occurred.
Like for example, (this is the only example I can think of right now):
-- You leave your bicycle outside in the rain, and it gets wet, and
a few days later there's some rust on it.
-- You scrape off some of the rust, take it to school, give it to the
Chemistry teacher, and ask her to analyze it and tell you what it
is. Later that day, she tells you it's a substance called "Iron oxide".
-- Where did that come from ? There was no iron oxide there.
There was only iron in the bicycle, and air, and water.
-- The iron oxide formed from a chemical change when the iron
on the surface of the bike combined with some of the oxygen in
the air, and molecules of a new substance were created. (For
some reason, the presence of water makes this chemical reaction
go faster.)
The pressure at the depth 11 km below sea level can be
calculated using
P=ρgh
P is pressure, ρ is the density of the fluid; g is the
gravitational constant, h is the height from the surface, or depth that the
object is submerged.
P = ( 1000 kg/ m3) ( 9.81 m.s2)( 11 000m) + 1 atm
P = 107,910,000 pa ( 1 atm/ 101 325 Pa) + 1 atm = 1066 atm
The formula for acceleration is the velocity times the inverse of time so it would be 21 times 1/13. So roughly 0.0769... is the acceleration(m/s^2).
