Weight = (mass) x (gravity)
= (75kg) x (9.8 m/s²)
= 735 kg-m/s²
= 735 newtons .
The weight of a barbell acting on a weightlifter in 80 N represents Fg.
<u>Explanation:</u>
Force exerted due to earth's gravity is represented as Fg. The gravitational pull is experienced by the mass of object has some force attached to by it which is called as force due to gravity.
The force is dependent upon the mass of the object experiencing the force. Hence the weight of a barbell acting on a weightlifter 80 N is the best example for Fg.
<span>The reason why the shapes of the continents as of
today do not perfectly fi into to super continent because long time ago the
super continent was scattered into pieces. And as times go by, those smaller
parts of super continents undergo soil erosion caused by the water and other
way that causes their original shapes change.
Thus, if we are going to judge now if those smaller part of super continent,
they’re no longer gonna fit perfectly because through time their original form
changed</span>
Air pressure is proportional to the square of the wind velocity.
Wind speed is how fast wind goes and atmospheric pressure is the pressure that the atmosphere pushes on us. The greater the difference in barometric pressure from a high pressure zone to a low pressure zone, the greater the wind velocity will be.
Hope this helped!
