Answer:
atmosphere is the mixture of gases that surrounds the Earth.
Answer: B
Explanation: sorry if I'm too late but i just did this question and that was the right answer
Answer:
A. False
B. True
C. False
Explanation:
- A. After the excess sucrose has crystallized out, the remaining solution is not saturated.
This is false, once the excess sucrose has crystallized out, the remaining solution is saturated. There's as much sucrose as can be in that amount of water at that temperature.
- B. After the excess sucrose has crystallized out, the system is now stable and is in equilibrium.
This is true, it is stable because it will not change by itself, it is in equilibrium because the rate of sucrose molecules leaving the surface of the crystals to be hydrated by water is equal to the rate of sucrose molecules in water attaching to the surface of the crystals.
- C. Is false because the system is in equilibrium, so the two rates are equal.
<u>Given:</u>
EMF = 0.88 V
Strength of magnetic field, B = 0.075 N/A-m
Velocity, v = 4.20 m/s
<u>To determine:</u>
The length of wire, L
<u>Explanation:</u>
The EMF is related to strength of the magnetic field B as:
EMF = L*B*v
L = EMF/B*v = 0.88/0.075*4.20 = 2.79 m
Ans: The length of the wire is around 2.8 m
