Answer: Think and you will get it right!
Explanation:
To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent.
1500 just move the decimal to the right three times because its a positive <span />
Time t=2.4 minutes=2.4×60=144 seconds
distance s=1.2 miles=1.2×1609=1930.8 meters
speed v=s/t=1930.8÷144=[tex] \frac{1930.8}{144} = \frac{160.9}{12} =[/13.408m/s ~nearly]
What question? Lhh this is hilarious.
m/s² aka meter per second squared.
acceleration = change in velocity/time
= distance/time
--
time
= m/s
--
s
=m/s^2
