Answer:

Following are the statement to this question:

Explanation:

The opinions were missing in this problem, which is why its solution can be described as follows:

The given statement better explains why the remote control communicates only with television to change the volume of sound because the Low energy has long waves and higher energy has shorter waves. Its remote control provides low energy radiation to both the light detector on the front of a TV, and it will be the only source for this type of radiation with less power and more than microwaves than visible light. When an object is not sufficiently hot to emit infrared radiation, a bulk of its power is infrared.

A plane has a cruising speed of 100 miles per hour when there is no wind. At this speed, the plane flew 600 miles with the wind

alina1380 [7]

The solution for this problem is:
Let x = speed of wind

Speed of plane with the wind = x + 100

Speed of plane against the wind = 100 -x

We will be using the formula for distance which is (Rate)(Time), getting the formula for time would be distance/rate Time to travel 600 miles with the wind = Time to travel 400 miles against the wind 600/(x + 100) = 400/(100 - x)

400(x + 100) = 600(100 - x)

400x + 40000 = 60000 - 600x

1000x = 20000

x = 20000/1000

x = 20 mph

Answer:

<h3>The answer is 8.29 %</h3>

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\% \\$

From the question

actual density = 19.30g/L

error = 20.9 - 19.3 = 1.6

We have

$p(\%) = \frac{1.6}{19.3} \times 100 \\ = 8.290155440...$

We have the final answer as
