Your experiment should keep one thing constant and measure the other. So vary the temp and measure the pressure. You will get a set of data that relates pressure with temp.
<span>PV = nRT
So
P and T are directly proportional.
</span>These experiments are one of either Boyle-Mariottte's, Gay-Lussac'a or Charles' law.
The acceleration of the car is 0.5 meters per seconds square.
Given the following data:
- Initial velocity, U = 30 m/s
Note: The final velocity (V) of the car would be zero (0) m/s when it comes to a stop.
To find the acceleration of the car, we would use the third equation of motion;
Mathematically, the third equation of motion is given by the formula;
![V^2 = U^2 - 2aS\\\\0 = 30^2 - 2a(900)\\\\0 = 900 - 1800a\\\\1800a = 900\\\\a = \frac{900}{1800}](https://tex.z-dn.net/?f=V%5E2%20%3D%20U%5E2%20-%202aS%5C%5C%5C%5C0%20%3D%2030%5E2%20-%202a%28900%29%5C%5C%5C%5C0%20%3D%20900%20-%201800a%5C%5C%5C%5C1800a%20%3D%20900%5C%5C%5C%5Ca%20%3D%20%5Cfrac%7B900%7D%7B1800%7D)
<em>Acceleration, a </em><em>=</em><em> 0.5 </em>
<em></em>
Therefore, the acceleration of the car is 0.5 meters per seconds square.

To solve this problem it is necessary to apply the concepts related to interference (destructive and constructive), as well as to the principle of overlap.
By definition we know that constructive interference is defined as
![dsin\theta = m\lambda](https://tex.z-dn.net/?f=dsin%5Ctheta%20%3D%20m%5Clambda)
Where,
d = Distance between slits
m = Order interference (Representing the number of repetition of spectrum)
wavelength
Re-arrange the equation to find the angle with the minimum order (m=1) we have,
![\theta = sin^{-1} (\frac{m *\lambda}{d})](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%20%28%5Cfrac%7Bm%20%2A%5Clambda%7D%7Bd%7D%29)
![\theta = sin^{-1}(\frac{1 * 640 * 10^{-9}}{0.01*10^{-3}})](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B1%20%2A%20640%20%2A%2010%5E%7B-9%7D%7D%7B0.01%2A10%5E%7B-3%7D%7D%29)
![\theta = 3.6690\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%203.6690%5C%C2%B0)
For the order of the missing interference we can calculate with the spacing of 0.05mm:
![m = \frac{d * sin\theta}{\lambda}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7Bd%20%2A%20sin%5Ctheta%7D%7B%5Clambda%7D)
![m = \frac{0.05 * 10^{-3}* sin 3.669}{640 * 10^{-9}}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B0.05%20%2A%2010%5E%7B-3%7D%2A%20sin%203.669%7D%7B640%20%2A%2010%5E%7B-9%7D%7D)
![m = 4.99 = 5](https://tex.z-dn.net/?f=m%20%3D%204.99%20%3D%205)
Therefore the smallest order interference maximum that is 'missing' from the interference/diffraction pattern on the screen is 5.
-- The theory of gravity gives a good explanation for things
that we see happening.
-- The theory of gravity predicts things that turn out to be true
when we test them.
-- Nobody has come up with a different theory that explains things better
and makes more accurate predictions that the theory of gravity does.
-- The theory of gravity can't be proved.
The
half-life of this radioactive isotope is 9 months for it decreases to
one-fourth its original amount in 18 months. Half-life means a certain length
of time after which half of the amount of radioactive element has decayed.
Therefore,
the half-life of this particular isotope is 18 months. After 18 months the
isotope was at one-half, then another 18 months, the isotope was at one-fourth,
which is 9 months where one-fourth is one-half of one half.
