The answer is Mars
Mars has a rotational period closest to that of Earth. Mars is roughly longer than a day on Earth. This is by far the closest by over a hundred hours. Other than Jupiter which rotates less than 10 hours. Mars has a rotation of 24.75 hours or 1.03 Earth days.
Answer:
<h2>
<em>True</em></h2>
Forests helps in binding the soil together. Thus, prevent soil from erosion.
Answer:
Option B: the period during which a solid is not changing state; its temperature is increasing
Explanation:
The temperature is defined as a measurement of the speed at which particles of matter are moving (their kinetic energy)
Therefore for an increase of kinetic energy to take place, and increase of temperature has to occur.
Answer:
To calculate the magnitude of a vector, just find the square root of the sum of components squared.
Explanation:
so square 2.6 and add it to the square of 6.8 and then the square of five and then find the square root of that answer
Answer:
5.1 m/s
Explanation:
The figure is missing: find it in attachment.
In order to find the average speed, we have to calculate the length of the total path, and divide it by the total time elapsed.
The curve from A to B is a quarter of a circle with a radius of r = 20 m, so its length is:
The path BC is the hypothenuse of a right triangle with sides equal to 20 m and 30 m, so its length is
Finally, the length of the path AC is the sum of the side of 30 m and the radius of the curve, so
So the total distance covered is
The total time elapsed is
So, the average speed is
