Answer:
0.41
Explanation:
A 49 N block has a mass of 5 kg:
49/9.8
A horizontal force of 50 N giving it an acceleration of 6 m/s^2 means that 30 N is taken up by the acceleration
This leaves 20 N to take care for friction. so the coefficient of friction is:
20/49 = 0.41.
Answer:
relative positions of Earth, the Moon and the Sun.
Explanation:
A lunar eclipse is a phenomenon that occurs when the Earth comes between the Moon and the Sun thereby causing it to cover the Moon with its shadow.
Simply stated, lunar eclipse takes place when the Moon passes or moves through the Earth's shadow thereby blocking any ray of sunlight from reaching the Moon. Thus, the full moon appears deep red (blood moon).
Also, a lunar eclipse would occur only when the Sun, Earth, and Moon are closely aligned to form a straight line known as the syzygy.
There are three (3) types of lunar eclipse and these are;
1. Total lunar eclipse.
2. Partial lunar eclipse.
3. Penumbra lunar eclipse.
Hence, the changing appearance of the Moon during the lunar cycle is the result of the changing relative positions of Earth, the Moon and the Sun.
<h3><u>Answer;</u></h3>
Sedimentary rock
Granite is uplifted by the movement of tectonic plates. It will most likely become a <em><u>sedimentary rock</u></em>.
<h3><u>Explanation</u>;</h3>
- Granite is an intrusive igneous rock that is coarse-grained and light-colored, mainly composed of feldspar and quartz. It forms from the crystallization or the cooling of magma in the Earth's crust.
- <em><u>When igneous rocks such as granite undergo weathering and erosion they form sediments that are deposited, then compacted and cemented by the movement of tectonic plates resulting to the formation of sedimentary rocks.</u></em>
Is this a test? If it is, i’m not allowed to help as i would be seen as a bad person! I hope you pass, god bless.
An astronomical unit is the measure of the center of the Earth to the center of the sun.
Because our solar system is so vast, using mere miles is ridiculous, because they are too small to be helpful and the numbers will be in the billions. Astronomical units make it easier to think in small amounts.
Hope this helps :)
