A. It will increase.
When the average movement of the particles in a material increases, it indicates that the kinetic energy of those particles is increasing, which correlates to a rise in temperature. Therefore, if the average movement of the particles in a sweater increases, the temperature of the sweater will also increase.

To find out how much money you need to pay annually in order to have a future value of $50,000 in 10 years at an interest rate of 5% per year, you can use the Future Value of an Annuity formula:
\[
FV = P \times \frac{(1 + r)^n - 1}{r}
\]
Where:
- \( FV \) is the future value of the annuity.
- \( P \) is the annual payment (the amount you want to find).
- \( r \) is the interest rate (expressed as a decimal).
- \( n \) is the number of periods (years).
Given:
- \( FV = 50,000 \)
- \( r = 5\% = 0.05 \)
- \( n = 10 \)
We need to solve for \( P \):
\[
50,000 = P \times \frac{(1 + 0.05)^{10} - 1}{0.05}
\]
Calculating \( (1 + 0.05)^{10} \):
\[
(1.05)^{10} \approx 1.628894626777442
\]
Now, subtracting 1:
\[
1.628894626777442 - 1 \approx 0.628894626777442
\]
Now calculate the fraction:
\[
\frac{0.628894626777442}{0.05} \approx 12.57789253554884
\]
Now we have:
\[
50,000 = P \times 12.57789253554884
\]
To find \( P \):
\[
P = \frac{50,000}{12.57789253554884} \approx 3973.25
\]
Therefore, you would need to pay approximately **$3,973.25** annually to have a future value of $50,000 in 10 years at an interest rate of 5% per year.
\[
FV = P \times \frac{(1 + r)^n - 1}{r}
\]
Where:
- \( FV \) is the future value of the annuity.
- \( P \) is the annual payment (the amount you want to find).
- \( r \) is the interest rate (expressed as a decimal).
- \( n \) is the number of periods (years).
Given:
- \( FV = 50,000 \)
- \( r = 5\% = 0.05 \)
- \( n = 10 \)
We need to solve for \( P \):
\[
50,000 = P \times \frac{(1 + 0.05)^{10} - 1}{0.05}
\]
Calculating \( (1 + 0.05)^{10} \):
\[
(1.05)^{10} \approx 1.628894626777442
\]
Now, subtracting 1:
\[
1.628894626777442 - 1 \approx 0.628894626777442
\]
Now calculate the fraction:
\[
\frac{0.628894626777442}{0.05} \approx 12.57789253554884
\]
Now we have:
\[
50,000 = P \times 12.57789253554884
\]
To find \( P \):
\[
P = \frac{50,000}{12.57789253554884} \approx 3973.25
\]
Therefore, you would need to pay approximately **$3,973.25** annually to have a future value of $50,000 in 10 years at an interest rate of 5% per year.

To determine which investment has a greater future value, we will calculate the future value for both Investment A and Investment B using the formulas for the future value of an annuity.
### Investment A:
- **Monthly Investment (P)**: $250
- **Number of Years (n)**: 10 years
- **Annual Interest Rate (r)**: 7% (or 0.07)
- **Number of Payments per Year**: 12
**Total Number of Payments (N)**:
\[
N = n \times 12 = 10 \times 12 = 120
\]
**Monthly Interest Rate (r)**:
\[
r_{monthly} = \frac{0.07}{12} \approx 0.0058333
\]
**Future Value (FV) Formula for Annuity**:
\[
FV = P \times \frac{(1 + r)^N - 1}{r}
\]
Substituting the values:
\[
FV_A = 250 \times \frac{(1 + 0.0058333)^{120} - 1}{0.0058333}
\]
Calculating \( (1 + 0.0058333)^{120} \):
\[
(1 + 0.0058333)^{120} \approx 2.221386025
\]
Now, substituting back:
\[
FV_A = 250 \times \frac{2.221386025 - 1}{0.0058333}
\]
\[
FV_A = 250 \times \frac{1.221386025}{0.0058333} \approx 250 \times 209.0866891 \approx 52,271.67
\]
### Investment B:
- **Annual Investment (P)**: $3,000
- **Number of Years (n)**: 10 years
- **Annual Interest Rate (r)**: 6% (or 0.06)
**Future Value (FV) Formula for Annuity**:
\[
FV = P \times \frac{(1 + r)^n - 1}{r}
\]
Substituting the values:
\[
FV_B = 3000 \times \frac{(1 + 0.06)^{10} - 1}{0.06}
\]
Calculating \( (1 + 0.06)^{10} \):
\[
(1 + 0.06)^{10} \approx 1.790847
\]
Now substituting back:
\[
FV_B = 3000 \times \frac{1.790847 - 1}{0.06}
\]
\[
FV_B = 3000 \times \frac{0.790847}{0.06} \approx 3000 \times 13.18078333 \approx 39,542.35
\]
### Conclusion:
- **Future Value of Investment A**: Approximately **$52,271.67**
