We can model a pine tree in the forest as having a compact canopy at the top of a relatively bare trunk. Wind blowing on the top

solmaris [256]

Answer:

114.075 N

798.525 Nm

Explanation:

C = Drag coefficient = 0.5

ρ = Density of air = 1.2 kg/m³

A = Surface area = 9 m²

v = Velocity of wind = 6.5 m/s

r = Height of the tree = 7 m

Drag equation

$F=\frac{1}{2}\rho CAv^2\\\Rightarrow F=\frac{1}{2}\times 1.2\times 0.5\times 9\times 6.5^2\\\Rightarrow F=114.075\ N$

Magnitude of the drag force of the wind on the canopy is 114.075 N

Toque is given by the product of force and radius

$\tau=F\times r\\\Rightarrow \tau=114.075\times 7\\\Rightarrow \tau=798.525\ Nm$

Torque exerted on the tree, measured about the point where the trunk meets the ground is 798.525 Nm

Without using a micrometer screw gauge, how do I find the average diameter of a long piece of thin wire using a metre rule and a

Mice21 [21]

Answer:

Wind the long piece of thin wire around the uniform glass rod multiple times, find the length of the total diameters using the metre ruler, and divide by the number of times you wound it around the rod.

Explanation:

Since the diameter of one long piece of thin wire is too thin to be measured by a metre ruler, you can wind it multiple times and push it side by side to get a length you can measure.

For example, if you wound it around 20 times and the total length of 20 diameters of the wire side-by-side is 2.0 cm, one winding, which is the diameter would be 2.0cm ÷ 20 = 0.10cm or 1mm.
