Explanation:

The formula to calculate mAs (milliampere - seconds) is \( \text{mAs}=\text{mA}\times\text{Time} \). We will apply this formula to each part (a - j) step by step.

Part a:

Step 1: Identify mA and Time

\( \text{mA} = 200 \), \( \text{Time}=\frac{1}{40}\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=200\times\frac{1}{40} \)
\( \text{mAs} = 5 \)

Part b:

Step 1: Identify mA and Time

\( \text{mA} = 400 \), \( \text{Time}=\frac{3}{10}\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=400\times\frac{3}{10} \)
\( \text{mAs}=120 \)

Part c:

Step 1: Identify mA and Time

\( \text{mA} = 300 \), \( \text{Time}=\frac{3}{5}\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=300\times\frac{3}{5} \)
\( \text{mAs}=180 \)

Part d:

Step 1: Identify mA and Time

\( \text{mA} = 100 \), \( \text{Time}=\frac{1}{20}\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=100\times\frac{1}{20} \)
\( \text{mAs}=5 \)

Part e:

Step 1: Identify mA and Time

\( \text{mA} = 600 \), \( \text{Time}=\frac{1}{4}\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=600\times\frac{1}{4} \)
\( \text{mAs}=150 \)

Part f:

Step 1: Identify mA and Time

\( \text{mA} = 100 \), \( \text{Time}=0.05\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=100\times0.05 \)
\( \text{mAs}=5 \)

Part g:

Step 1: Identify mA and Time

\( \text{mA} = 400 \), \( \text{Time}=0.017\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=400\times0.017 \)
\( \text{mAs}=6.8 \)

Part h:

Step 1: Identify mA and Time

\( \text{mA} = 300 \), \( \text{Time}=0.20\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=300\times0.20 \)
\( \text{mAs}=60 \)

Part i:

Step 1: Identify mA and Time

\( \text{mA} = 200 \), \( \text{Time}=0.33\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=200\times0.33 \)
\( \text{mAs}=66 \)

Part j:

Step 1: Identify mA and Time

\( \text{mA} = 1000 \), \( \text{Time}=0.006\text{ seconds} \)

Step 2: Apply the formula

\( \text{mAs}=1000\times0.006 \)
\( \text{mAs}=6 \)
