The number of significant figures in 5100 kg depends on how the number is presented. If it is written as 5100 with no decimal point, it typically has two significant figures. However, if it were presented as 5.100 x 10^3 kg or 5100. kg, it would imply four significant figures. Therefore, the context or notation used is crucial to determining the exact count.
5,100 in 3 significant figures is still 5,100.
