Answer:
The answer to the question is
The magnitude of the displacement needed to get the ball into the hole in just one putt is 1.746m in the direction of 23.41° north east
Explanation:
With trigonometric relation and the attached diagram we have
From the diagram the location of the hole is 3.32m- (1.57 cos45 +0.78co45)m North and
1.57sin 45 – 0.78 sin 45 meters west
1.658m north and
0.55m east
Thus the direction of the hole is 26.41 degrees
North east
The magbitude of the displacement is displacement is gotten from the relation diplacement of x and y =√(x²+y²)
∠26.41°
Full Question:
What is the Lewis structure of the covalent compound that contains one nitrogen atom, one hydrogen atom, and one carbon atom?
Explanation:
This covalent compound is the hydrogen cyanide, HCN.
The following steps are used to obtain it;
Step 1. Draw a skeleton structure of the compound based on the elements
Put the least electronegative atom C in the middle with H and Cl on either side.
H-C-N
Step 2. Count the valence (outermost) electrons you can use
H + C + N = 1 + 4 + 5 = 10
Step 3. Add these electrons to give every atom an octet
You have to put a triple bond between C and N.
Note: Each bond is made up of two electrons.
The lewis structure is given in the image below;
