Answer: F = 0.17N
Explanation: From the Newton second law of motion.
F= m(v-u)/t.
V=180km/hr = 180×1000/3600= 50m/s
U= 160km/hr = 160×1000/3600= 44.44m/s
t= 5secs
F=m(v-u)/t
F= 0.150(50-44.44)/5
F=0.150×5.56/5
F= 0.835/5
F= 0.17N rounded to two decimal places.
The planetary wind belts in the troposphere are primarily caused by the Earth's rotation and the unequal heating of Earth's surface.
Planetary wind belts are vast movements and they are driven by the circulation of air. The Sun's heat causes the winds around the world. It heats the tropical zone primarily than the polar regions because the sun's rays are more direct at the equator.
Answer:
Glassy texture
Explanation:
The rocks that are characterized by the absence of structure, shape, and size are usually referred to as the glassy texture. These rocks are comprised of atoms that are randomly oriented. These rocks are lacking in crystals because of their faster rate of cooling. It cools so fast that it does not get a sufficient amount of time to form crystals. For example, Obsidian.
This glassy textured rocks are found in the igneous types of rocks that are formed due to the cooling of magma.
Answer:
"The idea behind thermal expansion is that gases expand as the temperature increases. If you have a balloon and you heat up the contents, the balloon will get larger. Scientists use the term ideal gas law to describe this activity. Liquids expand and contract, too, but there is a lot less change than in gases."
I don't know if this is what u meant, but, hope this helps :3
Answer:
a. its constitution and mixed government.
Explanation:
Polybius tell us about the Roman mixed constitution as a fundamental in the Roman victory and the Carthaginian defeat in the Punic war, conceiving the mixed constitution as the best, since this constitution was at its peak, which implies that among the elements of the constitution, the aristocratic component was the dominant one.
