I think D. It starts at (0.0) and goes to the correct points so it makes sense

The answer is d because if you draw a line from (0,0) to (1,-3), that would overlap Ray d

The terminal speed of a sky diver is 130 km/h in the spread-eagle position and 326 km/h in the nosedive position. Assuming that

SIZIF [17.4K]

Answer:

$\frac{A_{slow} }{A_{fast} }=6.2885$

Explanation:

Given data

Terminal velocity for spread eagle position vt=130 km/h

Terminal velocity for nosedive position vt=326 km/h

The terminal speed of the diver is given by

$v_{t}=\sqrt{\frac{2mg}{CpA} }$

Therefore the area is given by

$A=\frac{2mg}{Cp(v_{t})^{2} }\\$

Since everything else is constant in the two dives except for the terminal velocity, the ratio between the area in the slow position to the area in the fast position is

$\frac{A_{slow} }{A_{fast} }=\frac{326^{2} }{130^{2} }\\\frac{A_{slow} }{A_{fast} }=6.2885$

Technician A says that the diameter of a bolt is the same as the wrench size used to remove or install the fastener. Technician

Iteru [2.4K]

Answer:

Neither Technician A or B

Explanation:

Both technicians are wrong. The diameter of bolt is not based on the top where wrench used, but on the smaller part below, it called shanks. Wrench size also not based on the top diameter but the width across the flat. The calculation for the length of a bolt also will not include the top/head, it only includes the shanks.

When removing the objects from the oven, you accidentally touch each one with your hand. Rank these objects on the basis of how

kykrilka [37]

Answer:

So, we can assemble the options based or evaluation of there properties regarding getting an equilibrium or balanced state in a given time.We have the following rankings attributed to the elements:

Silveringpot≥ aluminiumpot ≥ironskillet ≥glasscasseroldish ≥welldone steak ≥woodencuttingboard.

Explanation:

<u>Attaining equilibrium matters:</u>

When the materials are placed inside the oven, they attain a high temperature value causing it to be non touchable but some of the items has low value to attain the equilibrium state when comes in contact with other mediums. As these materials are also arranged based on that analyses.
