Answer:
26.309932 MN if gravity was normal gravity force and on basis salt water was 1030 kg/m3
Step-by-step explanation:
The rule below is something I just found.
To calculate the force of gravity of an object, use the formula: force of gravity = mg, where m is the mass of the object and g is the acceleration of the object due to gravity. Since g is always 9.8 m/s^2, just multiply the object's mass by 9.8 and you'll get its force of gravity
4√400 / 4√ 5 ( both are 'fourth roots ')
= 4√ (400/5)
= 4√80
= 2.99 to nearest hundredth
