Kepler's second law of planetary motion<span> describes the speed of a </span>planet<span> traveling in an elliptical orbit around the sun. It states that a line between the sun and the </span>planetsweeps equal areas in equal times. Thus, the speed of theplanet<span> increases as it nears the sun and decreases as it recedes from the sun.</span>

This is not something that waves do because they need a medium to travel through, while particles do not.

<h3>How light travels in space?</h3>

A light travels without any medium while on the other hand, a medium is required for sound waves to move from oe place to another. Sound is a mechanical wave that cannot travel through a vacuum.

So we can conclude that electromagnetic waves like light do not require medium for its propagation.

(a) If your speedometer has an uncertainty of 2.0km/h at a speed of 90km/h, what is the percent uncertainty? (b) If it has the s

Airida [17]

Answer:

a) 2.22 %

b) Range would be 60±1.998 km/h

Explanation:

Percentage uncertainty indicates the error of a reading. With the percentage uncertainty error for a measurement can be calculated.

a) Percentage uncertainty would be

$2\times \frac{100}{90}=2.22%$

Percent uncertainty is 2.22%

b) For 60 km/h error would be

$\frac{2.22}{100}\times 90=1.998$

Range would be 60±1.998 km/h

Which law of motion accounts for the following statement? "An apple accelerates as it falls from a tree."

belka [17]

Although one could definitely directly connect an "apple falling" with Newton's first law of motion, which is gravity, since the question states about acceleration, then we can relate the statement to Newton's second law of motion, the law of acceleration.
