A hunter hidden in a tree 90 feet above the ground spots two deer in the forest one is due West at the angle of depression of 24 degrees and the other is due at an angle of depression of 58 degrees?
Pancakes, because astronauts only kayak with pineapples.
How do you calculate roof pitch?
Place a four foot long level on the roof, parallel with the ground. With one end touching the roof and the other end in the air, read the bubble on the level. When the bubble says it is level, then have a second person measure the distance from the end hanging in the air straight down to the roof. Divide the number by 4. (example: with level bubble showing "level"; your helper reads 24 inches on the tape measure-- you divide 24 by 4 = 6" Your roof pitch is 6 /12, or 6 in 12." Every 12 inches of level travel your roof goes up 6 inches.
Are all rotations tornadoes?
No. A tornado is defined as a violently rotating column of air extending from the based of a thunderstorm to the ground. In order to be considered a tornado the circulation must:Be composed primarily of air (as opposed to water or some other fluid)Be associated with a parent thunderstorm.Be in contact with both cloud base and the ground.Produce winds at ground level strong enough to cause damage.Because of this, a number of atmospheric circulations are not considered tornadoes.
How do you use a theodolite?
Process of Measuring Horizontal Angles Using a Theodolite 1. Setting up the Theodolite: This includes mounting the theodolite on a tripod and making sure it is comfortable for the user. 2. Unlock the upper horizontal clamp. 3. Rotate the theodolite until the arrow in the upper or lower rough sight points to the feature of interest and lock the clamp. 4. Look through the main eyepiece and use the upper horizontal adjuster to align the vertical lines on the feature of interest. 5. The reading is taken by looking through the small eyepiece. Using the minutes and seconds adjuster set the one of the degrees on the horizontal scale so the single vertical line on the bottom scale is between the double vertical lines under the selected degree. 6. The reading is the degree which has been aligned and the minutes and seconds read from the right hand scale and is the horizontal angle from the reference line. Process of Measuring Vertical Angles Using a Theodolite Process of Measuring Vertical Angles 1. Setting up the Theodolite: This includes mounting the theodolite on a tripod and making sure it is comfortable for the user. 2. Unlock the vertical clamp and tilt the eyepiece until the point of interest is aligned on the horizontal lines. Lock the clamp in place. 3. Looking through the small eyepiece, use the minutes and seconds adjuster to align one of the degrees on the vertical scale with the double lines just below it. 4. The reading is the degree that has been aligned and the minutes and seconds is read from the right hand scale. 5. To complete the reading, it may be necessary to measure the distance from the theodolite to the point of interest. The above is al true, but doesn't discuss the practical uses of a theodolite. For example, if you want to know the height of the top of the gable on a house, you could use a theodolite. First, set up the theodolite (btw, I made one with a piece of copper tube, a protractor and a cheap wooden tripod) as noted above, make sure the ground is pretty level between the house and the theodolite, and then measure the distance from the vertical side of the house to the theodolite. (You may choose to move the theodolite so that the distance is the square of a whole number.) Then aim the scope (tube) at the upper-most point of the gable and note the degree of angle on the protractor. If you have pretty level ground between the theodolite and the house, the angle at the intersection of the side of the house and the ground should be 90 degrees. So, now we have two angles (the 90 degrees at the intersection of the side of the house and the ground, and whatever angle you recorded at the theodolite) and a side (the distance from the house to the theodolite). With this information, you can calculate the third angle and the other two sides, one of which will be the hypotenuse and the other will be -- tada! -- the final leg, which will tell you the height of the point you picked out at the top of the gable.

The amount of gravitational potential energy that an object has depends on its weight and?
Weight, height above the ground level (or other reference level), the strength of the gravitational field.Weight, height above the ground level (or other reference level), the strength of the gravitational field.Weight, height above the ground level (or other reference level), the strength of the gravitational field.Weight, height above the ground level (or other reference level), the strength of the gravitational field.
A ball held above the floor has what type of energy?
Any object above ground level has gravitational potential energy. Actually, ground level is commonly chosen as the reference level, but any other level may be chosen as well. The choice is arbitrary.
If ground level is 0 and the first level above ground id 1 which integers can you use to represent the other levels where objects are hidden. Explain your reosoning?
-1,-2,-3
Sitting down at a table not moving what kind of energy exists?
There is potential energy, which is non-zero if you are above ground level (or above, or below, any other reference level you choose).
How do you get in school on wimpy wonderland?
First, you have to move the trash can so that it is on the seesaw. Then jump on the other end of the seesaw, to see the trash can fly to the top level. Move the trash to the far left end of the top floor and jump on it into the building!
What is a seesaw stunt?
A seesaw stunt is something performed commonly at a circus. It is when one person stands on a seesaw and another person jumps on the other end causing the first person to flip off the seesaw.
How is ground-level ozone and smog related?
Ground level smog and ozone are related with each other. They both act as pollutants at ground level.
Characteristics of gravitational potential energy?
It isn't clear to me what you mean with "indicators" - an object has positive gravitational potential energy if it has mass, and if it is above ground level (or above any other reference level you choose to define as level zero).
Why does it sleet sometimes and snow at other times when its the same temperature?
It may be the same temperature at ground level but the temperature (and behaviour) of the air column above you will be different.
Can the gravitaional potential energy of an object be negative?
Yes. Any object that is above a reference level has positive potential energy; anything below that reference level has negative potential energy. For example, if the chosen reference level is the ground level, anything below the ground level has negative potential energy. Please note that the choice of reference level is arbitrary. What matters is the DIFFERENCE in potential energy between two positions - and that doesn't change, whether you choose (for example) the ground level, or some other level, as a reference level.
What is the physics of a seesaw?
A seesaw in physics is a Class 1 Lever. One rider can be called the force, the other rider is then the load, and the fulcrum is between the two.
