Which one of the following words is not an action verb? (2 marks) ans. Trained tested designed happy.

adelina 88 [10]

The option that is not an Action Verb is; D: Happy

<h3>What is an action verb?</h3>

An action verb is simply defined as a verb that describes different actions such as run, jump, kick, eat, break, cry, smile e.t.c.

Now, in the question, trained, tested and designed are action verbs because they describe actions that are performed by people whereas being happy is not an action but a feeling.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. the angle

Mekhanik [1.2K]

The height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

<h3>What is right angle triangle property?</h3>

In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.

$\tan\theta=\dfrac{b}{a}$

Here, (b) is the opposite side, (a) is the base side.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence.

The angle of elevation of the tree from one position on a flat path from the tree is

$H=40^o$

From a second position,

$I=60\rm\; ft$

Farther along this path it is,

$b=30^o$

Let the distance between tree and first position is x. Thus, from the trigonometry,

$\tan 40=\dfrac{h}{x}\\h=x\tan 40$ ....1

The distance between tree and second position is (x+60) ft. Thus, again from the trigonometry,

$\tan 30=\dfrac{h}{x+60}\\h=(x+60)\tan 40$ ......2

Compare the equation 1 and 2,

$x\tan (40)=(x+60)\tan 30\\0.839x=0.577x+34.64\\0.839x-0.577x=34.64\\x=\dfrac{34.64}{0.262}\\x=132.25\rm\; ft$

Put this value in equation 1 as,

$h=(132.25)\times \tan40\\h\approx111\rm\;ft$

Thus, the height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

Which of the following can be represented by a single binary digit?

algol [13]

Answer:

A single binary digit can only represent True (1) or False (0) in boolean logic. However, multiple binary digits can be used to represent large numbers and perform complex functions. In fact, any integer can be represented in binary. ... A byte contains eight bits, which means it can have 256 (28) different values.

List the following compounds in decreasing electronegativity difference.

nikdorinn [45]

Answer:

Based on Pauling Scale, electro negativity of Cl = 3.2, Na = 0.9 and H = 2.1

Explanation:

Thus, Electronegativity difference in Cl2 = 3.2 -3.2 = 0

Electronegativity difference in NaCl = 3.2-0.9 = 2.3

Similarly, Electronegativity difference in HCl = 3.2 - 2.1 = 1.1

Thus, among the listed molecules following is the decreasing order of electronegativity difference: NaCl> HCl > Cl2
