The strong man cant hold a weight on a chain completely straight due to the gravity and the mass of the chain/chair,
<span>Acceleration due to gravity at surface radius = approx 23 (m/s)/s</span>
The question is incomplete and no options are given but the answer is;
The orbit of Mars is an ellipse,<span> is generally attributed to Kepler.
Kepler's first law states that; "</span><span>The orbits of the planets are ellipses, with the Sun at one focus of the ellipse.
</span>The planet at that point takes after and follow the ellipse in its orbit, which implies that the distance between Earth and Sun remove is continually changing as the planet goes around its orbit.
A :-) 1.) 3rd law of motion.
2.) 2nd law of motion ( law of inertia ).
- 2nd law states that if an object has more mass then it has more inertia ( mass = inertia ).
So , here the empty shopping cart is easier to push compared to loaded one.
3.) 1st law of motion.
- 1st law states that a object in rest will stay at rest , if a object is in motion it will stay at motion until a unbalanced force is applied on it.
So , here the baseball was in motion then , an unbalanced force ( bat ) was applied on it , so the was thrown up into the air.
4.) 3rd law of motion.
- 3rd law states that every action force has an equal and opposite reaction force.
So , here when your walking , your foot pushes the ground backwards ( action force ) , and the ground pushes your foot forward ( reaction force ).
5.) 1st law of motion.
