Questions & Step-by-Step Solutions

What is the scalar product of A = (3, 4, 0) and B = (0, 0, 5)?
  • Step 1: Identify the components of vector A, which are (3, 4, 0).
  • Step 2: Identify the components of vector B, which are (0, 0, 5).
  • Step 3: Multiply the corresponding components of A and B: 3 * 0, 4 * 0, and 0 * 5.
  • Step 4: Calculate each multiplication: 3 * 0 = 0, 4 * 0 = 0, and 0 * 5 = 0.
  • Step 5: Add the results of the multiplications together: 0 + 0 + 0.
  • Step 6: The final result is 0, which is the scalar product of A and B.
