Answer:
a. 1,188 N
b. 1.836
Explanation:
The computation is shown below:
a. For horizontal force, first we need to find out the circular path radius which is shown below:
As we know that
= 8m
Now the horizontal force is
where,
m = 66 kg
v = 12 m/s
and r = 8 m
Now placing these values to the above formula
So, the horizontal force is
= 1,188 N
b. Now the ratio of force to the weight of skater is
= 1.836
Answer:
Explanation:
From the question we are told that
The number of slits per cm is k = 
The order of the maxima is n = 1
The wavelength are 
The spacing between the slit is mathematically represented as
=> 
=> 
Generally the condition for constructive interference is
At 
![\theta _1 = sin^{-1} [ \frac{1 * 434 *10^{-9}}{6.211 *10^{-5}} ]](https://tex.z-dn.net/?f=%5Ctheta%20_1%20%20%3D%20%20sin%5E%7B-1%7D%20%5B%20%5Cfrac%7B1%20%20%2A%20%20434%20%2A10%5E%7B-9%7D%7D%7B6.211%20%2A10%5E%7B-5%7D%7D%20%5D)

Answer:
b-testing
Explanation:
First would be observation/research. Then the hypothesis. After that you would test your theory, conduct experiments. And finally, your conclusion- what you got from the whole process basically.
Hope this helps.
Answer:
Change in position of an object A vector quantity with unit of distance.
Explanation:
Where is the object going? Final - initial
If you're willing to consider fractions or decimals,
then there are an infinite number of answers.
Like (2.5 x 160), and (15 x 26-2/3).
If you want to stick to only whole numbers,
then these 8 combinations do:
1, 400
2, 200
4, 100
5, 80
8, 50
10, 40
16, 25
20, 20
