How long to reach the ground from the maximum height
First, calculate the time of flight (T)
The time taken (t) from maximum height to the ground is:
So, we have:
Another representation is:
At ymax, the time is: t1
On the ground, the time is t2
The difference between these times is the time taken.
So;
Since air resistance is to be ignored, then
--- i.e. time to reach the maximum height from the ground equals time to reach the ground from the maximum height
Becuase of the earths gravitational pull you wont feel it because the earth is pulling you already and you arent big enough to feel the pull between the 2
<span>The metric
system is the oldest name for the international system of units. The answer is <u>a.
True. </u>SI unit or the international systems of units are based on seven
basic units; the meter, kilogram, second, ampere, Kelvin, candela and mole. All
of these basic units are divided into multiples by a power of ten. For example
in meters, 1 meter is equal to: 1000 millimeter, 100 centimeter, 10 decimeter,
0.1 decameter, 0.01 hectometer, 0.001 kilometer and so on and so forth.</span>
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
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,
For the order of the missing interference we can calculate with the spacing of 0.05mm:
Therefore the smallest order interference maximum that is 'missing' from the interference/diffraction pattern on the screen is 5.
