Question

1. how many watts of electricity does it take to power the ball?

$5 \times 10^4$

Explanation:

Step1: Understand the scientific notation

The given value is \( 5 \times 10^{4} \) (assuming it's \( 5\times10^{4} \) as \( 10^4 \) is 10000, maybe a typo in the original with \( 104 \) meant to be \( 10^4 \)).

Step2: Calculate the value

To find the actual number of watts, we calculate \( 5\times10^{4} \). We know that \( 10^{4}=10000 \), so \( 5\times10000 = 50000 \).

Answer:

50000 (assuming the original \( 5\times104 \) is a typo and should be \( 5\times10^{4} \); if it's literally \( 5\times104 \), then \( 5\times104 = 520 \))
