Explanation:
1N=9,81 kg
1. 9,81×500×10=<u>49.050</u>
2. 9,81×100×40=39.240
option 1 does more wor
<span>a = (v2 - v1)/t= acceleration formula
a = (70 - 0)/7
a = 10 km/hr/sec
-----
It's better to use as few units as possible.
10 km/hr = 10 km*1000 m/km/(1 hr*3600 sec/hr) = 25/9 m/sec
a= 25/9 m/sec/se</span>
'Pressure' is (force) / (area).
The only choice with those units is #1 .
