-- The wavelength and the amplitude were described in my answer to your previous question.

-- A "compression" is a place where the wave is <em>compressed</em>. It's the darker section of the wave in the picture, where the wavelength is temporarily shorter, so several waves are all bunched up (compressed) in a small time.

-- A "rarefaction" is exactly the opposite of a "compression". It's a place where the wave gets more "<em>rare</em>" ... the wavelength temporarily gets longer, so that several waves get stretched out, and there are fewer of them in some period of time. The arrow in the picture points to a rarefaction.

Two men pull on a 31-kg box with forces 8.3 N and 6.6 N in opposite directions.

kykrilka [37]

The resultant acceleration of the box is 0.055 m/s² in the direction of the greater force.

The given parameters:

Mass of the box, m = 31 kg
Two applied forces, = 8.3 N and 6.6 N

<h3>Resultant force on the box</h3>

The resultant force on the box is calculated as follows;

$F_{net} = F_1 - F_2\\\\F_{net} = 8.3 \ N - \ 6.6 \ N\\\\F_{net} = 1.7 \ N$

<h3>Resultant acceleration of the box</h3>

The resultant acceleration of the box is calculated as follows;

$F = ma\\\\a = \frac{F}{m} \\\\a = \frac{1.7}{31} \\\\a = 0.055 \ m/s^2$

Thus, the resultant acceleration of the box is 0.055 m/s² in the direction of the greater force.

Answer:

Drought

Explanation:

If you are asking about Number 2. then the answer would be lack of precipitation (rain).

Climate change didn't allow for cold air to meet the warm air to produce precipitation over the run off area of the lake.

Electricity costs 10p per unit. How much will it cost Sam to use a 85W laptop and a 60W lamp for an hour?

Goryan [66]

The standard unit is KW/hr, = 1,000W/hr.
(85 + 60) = 145W.
You need to find its fraction of 1,000W., so (145/1000) = 0.145 KWH.
(0.145 x 10p) = 1.45p. per hr.
