Your welcome
Zero latitude gets the most direct sun all year around. That's the equator.
The picture you attached has nothing to do with this question.
Answer:
<h2>
4519.60 J/K</h2>
Explanation:
Change in entropy is expressed as ΔS = ΔQ/T where;
ΔQ is the total heat change during conversion of ice to water.
T is the room temperature
First we need to calculate the total change in heat using the conversion formulae;
ΔQ = mL + mcΔθ (total heat energy absorbed during phase change)
m is the mass of ice/water = 900g = 0.9kg
L is the latent heat of fusion of ice = 3.33 x 10⁵J/kg
c is the specific heat capacity of water = 4200J/kgK
Δθ is the change in temperature of water = 10°C - 0C = 10°C = 283K
Substituting the given values into ΔQ;
ΔQ = 0.9(333000)+0.9(4200)(283)
ΔQ = 299700 + 1069740
ΔQ = 1,369,440 Joules
Since Change in entropy ΔS = ΔQ/T
ΔS = 1,369,440/30+273
ΔS = 1,369,440/303
ΔS = 4519.60 J/K
Hence, the change in entropy of the universe is 4519.60 J/K
Remark
All the statements are correct except for B
B is wrong because the Force is inversely proportional to the square of the distance.
D is correct. That's what Newton saw when he watched the apple fall. The apple did all the moving.
A is correct. The formula is
F = G*m1*m2/r^2
If r is held constant the formula becomes
F = k * m1 * m2 where k = G/r^2
C is true as well, but it sure decreases in strength because of the distance and the smallness of G.
