2 answers:
Ede4ka [16]3 years ago
4 0

The correct answer is

D- 4 watts


In fact, the different prefixes correspond to the following:

kilowatt: 1 kW = 10^3 W

megawatt: 1 MW=10^6 W

gigawatt: 1 GW=10^9 W


Using the list above, we can convert all the options into Watts:

A) 1 GW=1 \cdot 10^9 W

B) 2 kW=2 \cdot 10^3 W

C) 3 MW=3 \cdot 10^6 W

D) 4 W

Therefore, the smallest quantity is D) 4 Watts.

<span>D is the correct answer. A watt is the smallest amount of power. The prefix kilo means a thousand, mega means a million and giga means a billion, so, in increasing size: watt - kilowatt - megawatt - gigawatt.</span>

A 5. 3 ft -ft-tall girl stands on level ground. The sun is 30 ∘ above the horizon. How long is her shadow?
slamgirl [31]

The trigonometric ratios are sine, cosine and tangent. We can use cosine to find the length of the shadow from the calculation as 1.7 ft.

<h3>What is trigonometric ratio?</h3>

The term trigonometric ratio has to do with sine, cosine and tangent which are used to solve problems that involve the right angled triangle.

Using the geometry of the right angle triangle, we can find the tangent of the angle 30 in order to obtain the length of the shadow.

Tan 30° = opp/3

opp = 3Tan 30°

opp = 1.7 ft

The length of the girl's shadow from the calculation is 1.7 ft.

What phase difference between two otherwise identical harmonic waves, moving in the same direction along a stretched string, wil
lora16 [44]

Answer:

\theta=145

Explanation:

The amplitude of he combined wave is:

B=2Acos(\theta/2)\\

A, is the amplitude from the identical harmonic waves

B, is the amplitude of the resultant wave

θ, is the phase, between the waves

The amplitude of the combined wave must be 0.6A:

0.6A=2Acos(\theta/2)\\ cos(\theta/2)=0.3\\\theta/2=72.5\\\theta=145
