Answer:

d) all notebooks would fall at the same time

Step-by-step explanation:

One thing you learn in Physics class is that acceleration due to gravity is the same for all objects: their change in speed as a function of time is not dependent upon their weight.

For similar objects (notebooks) falling from desk-top height, the effect of air resistance is probably negligible, and is unlikely to be measurable in a casual experiment of the sort described here.

_____

If you assume heavier objects fall faster, then answer selections b and c both would have to be correct. If you assume there is only one correct answer, it must be d.

A young boy let’s out 30 feet of string on his kite. If the angle of elevation from the boy to his kite is 27”, how high is the

const2013 [10]

Answer:

The height of the kite from the ground is 13.617 feet

Step-by-step explanation:

Given as :

The measure of the string = 30 feet

The angle of elevation from the boy to his kite = 27°

Let the height of the kite from ground = H feet

So, From Triangle

Sin angle = $\dfrac{\textrm perpendicular}{\textrm Hypotenuse}$

Or, Sin 27° = $\dfrac{\textrm H}{\textrm 30}$

or, H = 30 × Sin 27°

I.e H = 30 × 0.4539

∴ H = 13.617 feet

Hence the height of the kite from the ground is 13.617 feet Answer

The complement of an angle is 8 times as large as the angle. find the measure of the complement

Feliz [49]

Complement angles means that the sum of the two angles equal to 90°.
Thus,
x + 8x = 90
9x = 90
x = 10°
8x = 80°
The complement is 80°
