# Your Questions About X100

Jenny asks…

## Why is my golf ball flight so high?

With all my woods I average fairly solid distances and trajectory (285 Driver, 255 3 Wood, 225 20* Hybrid), but my irons I hit very high and they don’t really go very far. The trajectory is off and it really just climbs and then falls out of the sky. (132 9 iron, 100 52* Wedge). I play Titleist AP2 irons with S300s and I have Titleist SM4 Vokey Wedges. My average iron swing speed is 90 mph, average driver swing is 110+ mph. So I know I have the clubhead speed to hit the ball far, but something is causing the flight to be really high. Also, I’ve read that the AP2 irons are designed to get the ball in the air so maybe that’s the reason? Also, I played with a semi strong grip and a cupped wrist. I compress the ball just fine and can draw or fade it so I doubt the cupped wrist at the top has anything to do with it. (Charl Schwartzel is the same way). I see these guys on tour hit knock down 8 irons from 162 and to hit anything 162 I need to belt a 7 iron or hit a choke 6 iron.

Note: I’ve tried using Dynamic Gold **X100** shafts to lower the flight, but it was almost identical to what I have now. And if I try and just smash an iron to get a few extra yards from it, the ball flight is even higher and sometimes doesn’t even go the normal distance with a smooth swing. Now I will be honest and say that my bad shot is a weak fade because I don’t square the club sometimes, but even when I hit a really solid draw, I might get 2 or 3 extra yards out of each iron. Also, I’m 6 foot 2 so I know because I create a larger arc that it gets the ball in the air more, but I don’t think that would cause me to have such weak iron shots.

Does anyone have any tips/suggestions or previous experience with this problem? Should I get fitted for Irons with a lower flight like X Hot Pros or Rocketbladez Tour? Thanks for the input!

### Administrator answers:

I had the same problem, my golf coach told me that I was trying to help the ball up instead of staying behind the ball and hitting the ball right on the nose.

## How to calculate stomatal density?

The question shows a photograph of the lower epidermis of a leaf. Its magnification is **x100**.

Then it says: the area of the field view is 0.102mm^2. Count the number of stomata present and then calculate the number per mm^2.

Ok, so I counted the number of stomata in the photograph, and there are 14. Am I just dividing 14 by 0.102? The answer I got was 137.254…mm^2

That answer seems improbable… What am I missing?

### Administrator answers:

You are nearly correct:

- the answer should be rounded to 2 or 3 significant figures because that’s is the precision of the data you are using;

- the unit is not mm^2, but ‘stomata/mm^2′

So I would give the answer as:

140 stomata/mm^2 or

137 stomata/mm^2

This sound perfectly reasonable – it just means that each square mm of leaf contains about 140 stomata. Nothing wrong with that.

Chris asks…

## Picking a front yard tree. Sunburst Locust or Mountain Ash?

We have a fairly small lot in a new subdivision 43′**x100**‘. We’re trying to decide on a tree for the front of the house. We have it narrowed between a Sunburst Locust or a Mountain Ash.

My wife has heard that mountain ash is a dirty tree but I understand they don’t drop their berries till early winter when the snow is on the ground anyway.

Anyone have experience with these trees. What would you suggest?

### Administrator answers:

I have both and although the mountain ash looks spectacular with it’s red berries and the birds it attracts, the Sunburst Locust is the winner in my books. The color is gorgeous and the way the sun filters through the leaves is a picture in itself. When it’s flowers are in bloom, early summer it attracts flocks of American Goldfinch who eat the seeds. They are the same color as the tree so it’s hard to see them unless they are flitting about. Beautiful little birds.

Enjoy, they are both easy to grow,

Betty asks…

## How do I calculate a percentage increase from 1 number to another?

How do I calculate a percentage increase from one number to another? For example, if someone had a income of $5 from their little business (like some kid’s juice stand). The next year the the kid made $100. Wouldn’t that be an increase in income of 1500%? Same with debt. If someone went from losing $1 in income to $100, that would be an increase in loses of 9900%, correct?

### Administrator answers:

100 $ – 5$ = 95 $

Increase % = 95/5 X100 = 1900% ANSWER

Increase in loss = 100 -1 = 99 $

Loss % = 99/1 X 100 = 9900% ANSWER

Steven asks…

## What is the energy ( in joules) of an extremely powerful gamma ray with a wavelength of 10^-7 nanometers?

Also how many of these gamma ray photons would have the same amount of energy as a housefly, which has a kinetic energy of about one millionth of a joule as it flies along?

If you could give me a detailed explanation of these 2 questions it would be appreciated…

The formulas I need used are E= h X c / wavelength

and Wavelength X v = C

Thanks in advance : )

### Administrator answers:

E = hc/w is the equation you need

h is Planck’s constant and is equal to 6.63×10^(-34)J s

c is the speed of light and is equal to 3.00×10^8m/s

w is the wavelength

In this case the wavelength is given as 10^(-7) nanometers.

The conversion factor is 1 Nanometer = 1E-09 Meters

so w = 10^(-7)x10^(-9) meters = 10^(-16) meters

E = (6.63×10^-34)x(3.00×10^8)/(10^(-16)) Joules

E = (6.63×3)(10^(-10)) Joules

E = 1.98×10^(-9) Joules

Kinetic energy of fly is 10^(-6) Joules

Number of gamma rays = 10^(-6)/[1.98x10^(-9)]

Number of gamma rays = (10/1.98)x100 = 505

About 500 such gamma rays would be needed to have about the same kinetic energy as a fly

David asks…

## How many footing of fence would you need for a circular fence that fit just inside a 100×100 foot square?

How long did it take you to answer?

### Administrator answers:

If the circle fits inside a 100′x100′ square, then the circle’s diameter is 100′. The amount of fencing is simply the circumference of the circle, which is 100? Feet, or approx 314 feet.

(about 22 seconds)
