Answer:
C Iqaluq's observation belies a wider phenomenon. In summer 2020, due to intense summer heat, sea ice in the Arctic melted to its second-lowest extent on record.
Explanation:
Logic refers to the use of evidence to support one's argument. Statistics, facts, and data are used to back up the writer's argument. In the third option, the writer uses facts and figures to support his argument. He cited data on the Arctic melting in the summer of 2020.
The importance of logical reasoning is that the reader can reach a conclusion through the premises cited by the author. It is even more beneficial if the premises are data that can be verified.
Answer:
2.136 N-m
Explanation:
From the question,
Applying,
Toque = FL...................... Equation 1
Where F = Force applied to the the ball, L = Length of the forearm
From newton's second law of motion,
F = m(v-u)/t................. Equation 2
Where m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time.
Given: m = 0.140 kg, u = 0 m/s (from rest), v = 24 m/s, t = 0.425 s
Substitute into equation 2
F = 0.140(24-0)/0.425
F = 7.91 N.
Also Given: L = 0.270 m
Substitute into equation 1
Torque = 7.91×0.270
Torque = 2.136 N-m
Earth DOESN'T have a giant bar magnet inside it; instead, our planet's magnetic field is made by swirling motions of molten iron in Earth's outer core. ... The magnetic poles are near, but not quite in the same places as, the geographic poles. The needle in a compass points towards a magnetic pole
The International System of Units is the modern form of the metric system. It is the only system of measurement with an official status in nearly every country in the world. ..
SI <em>SYSTEM</em><em> </em><em>WAS</em><em> </em><em>DEVELOPED</em><em> </em><em>BECAUSE</em><em> </em>
It allows people in different places and different countries to use the same units, avoid mistakes and understand each other more easily. The common base 10 of all units makes it easier and has more accurate calculations that are made without cumbersome conversion factors.....
