20 if i am correct lowest 2 digit number is 10
8.71 xx10^(12)
The exponent is a positive number. This means the decimal point moves to the right by the number of the exponent.
There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.
8.71 x 10^12 becomes 8,710,000,000,000.
Answer:
1750 m/s
Step-by-step explanation:
1km = 1000m
1 hour = 60 minutes = 3600 seconds
( 630 * 1000 )/ (60 * 60)
= 1750 m/s
I got 0.3125 (i don’t know if that’s correct, because the question was hard for me to understand)
