A) 75 kg
Answer^
Explanation:
a = Fnet / m : plug the numbers in
2.2 m/s ^2 = 165n /m : now cross multiple
22m / 165 : now divide 22 to both sides
M = 75
Answer:

Explanation:
The helium is formed during the natural radioactive decay of elements such as uranium and thorium. These heavy elements were formed before the earth but they are not stable and very slowly, they decay. One mode of decay for uranium is to emit an alpha-particle.
Answer:
to avoid iodine vapor from escaping.
Explanation:
This question is all about an experimental work on the determination of the distribution of iodine between waters and cyclohexane. To understand this question one has to understand the topic "Equilibrium" very well.
One important thing that must be noted in this question is for us to remember that water and cyclohexane are two immiscible liquids. So, when Iodine is added to the two solvents, the iodine dissolves in both water and cyclohexane to certain rate ands then to an equilibrium which is;
Kd = I₂[Cyclohexane]/ I₂[water]. ----------------------------------------[**].
There is a release of I⁻¹ From the added potassium iodide which helps in making sure that the iodine vapor does not escape. Thus, forming a tri-iodide ion.
Answer:Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. ... But because the Earth rotates, circulating air is deflected.
