Answer:
At the bottom when they hit the ground.
Answer:
Product, 
P = 639619.091888
Explanation:
In this case, we need to find the product of two numbers. These are as follows :


On doing calculation, we get the product of two numbers as :


P = 639619.091888
In scientific notation the product of two number is given by :

Hence, this is the required solution.
It’s D. An enlargement (hope this helps!)
The absolute refractive index is equal to the speed of light of the wave in air divided by the speed of light in the second medium. This means that it is equal to 3 x10^8 / 1.71 x10^8. This means the answer is 1.75
To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.
The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,


Equating both equation we have that,


Rearranging to find the angle we have that,

Our values are given as,




Therefore the minimum angle will be 11.53°
