Answer:
Step-by-step explanation:
Noon is 12:00
5am to 12noon is 7 hours
6,000 to 6,500
It grew by 500 in 7 hours
So one hour it is 500/7
In 12 hours that is from 12noon to 12midnight it will be 12×500/7+6500 since at 12noon it was 6500 that will be 6500+857=7357

It would be
3.5 × 10⁻³ kg.
The decimal point must be moved 3 places to the right in order to have it behind the first non-zero digit; this gives us the exponent of 3, and since we are moving the decimal to the right, it is a negative exponent.
