Barbed wire is nailed to a tree at a height of 1 meter. How high will the strand be after 15 years?

About one meter.\nThe growth comes from the apical meristem which is at the top.

You need to solve this using similar triangles.\nOne triangle is formed by the meter stick and the shadow (it is a right triangle)\nThe other triangle is formed by the tree and the shadow of the tree.  \nThese triangles are similar because the meter stick and the tree are both being hit by the same angle of sunlight.\n\nSo now that you have similar triangles, you can set up a proportion.\n\nx/5 = 1/0.4\n\nThen you can cross multiply:\n0.4x = 5\nThen divide both sides by 0.4 (multiply by 2.5)\n\nx=12.5\nThe tree is 12.5 m tall

(288^2)/(2*32.2) is the maximum height.\nat time 288/32.2 seconds\nit hits ground at time time   t+576/32.2, where t is obtained from\n45=288+.5*32.2*t^2

A length of a single wire:\nL^2 = 72*72 + 54*54 (from a right triangle)\nso L = 90 ft\nFour sets of wires -> he needs 360 ft

easy \n\nU make a triangle between the centers of the 3 circls \nmeaning it would have three lines = 2*R = 2m\nso the hight of the triangle would be root of ( R*R - 0.5R * 0.5R)\nso it would be the root of (3) which is( 1.73)\nthe hight would be 1 + 1.73+ 1 = 3.73 m

T = mg.\n\nThe length of the cable is irrelevant in this example. The beam is hanging off the cable.\n\nThe tension in the cable therefore is m*g, which is 2450 N.

Try to make it at 3 feet.  It will probably be easier.  I'd probably use balsa wood.

AGE OF THE TREE the rings inside 1 per year \nhurbs  dont know

Heres one good example. You are working as a lanscpaer. A person wants a 20 foot tree in their yard. You go to pick out a tree but you can't find the height of the trees except for one. You can use trig to find the hight of the other trees

your question doesn't make sense and is unclear - can you clarify it and then maybe i can help you?\n\ni got that a 100ft tower is erected, but is 100ft the actual length of it or the vertical distance it covers?  or is the tower erected straight vertically?  or normal to the hill? and the two wires (i assume you mistyped "guy")?  i don't really get it...

I'm pretty sure it's 15 feet by 300 feet. \nI think some "superpipes" can go as high as 18 feet.

About 30m (100 ft) high.

A comparable question: How long is a piece of string?

Long enough to reach the end of a hole

the most accurate answer is 170centimeters and 2 millimeters.. i got it from my meter tape
