Step 1
Which of these is a scalar quantity?
Answer
A scalar quantity is one that only has magnitude and no direction. In this case, the correct answer is B: distance, as both acceleration and force are vector quantities that include direction, while weight, although scalar in nature, is a force dependent on mass and gravity.
Step 2
The speed of the falling stack of cupcake cases depends on the number of cupcake cases in the stack.
Answer
As the number of cupcake cases increases, the speed at which they fall can be influenced by various factors including air resistance and weight. The more cupcake cases in the stack, the greater the mass, which can increase the gravitational force acting on them, potentially resulting in a faster descent until other forces such as air resistance become significant.
