<h3><u>Mass of an object affect the outcome of unbalanced forces:</u></h3>
Newton’s second law of motion deals with the result of motion of an object when unbalanced forces are applied. The second law of motion establish the relationship between mass, acceleration and unbalanced forces of the object. The below points explains the relation between unbalanced forces acting on mass of the object. The acceleration of object would be higher when the unbalanced force is higher.
The equation for the unbalanced force is,
For Example: Two masses of 500 kg and 1 kg is applied with same unbalanced forces. The change in motion of 500 kg would be very much less than the change in motion of 1 kg.
Momentum = (mass) x (speed)
Original momentum = (700 kg) x (30 m/s) = 21,000 kg-m/s
Final momentum = (700 kg) x (15 m/s) = 10,500 kg-m/s
Change in momentum = - 10,500 kg-m/s .
It's a virtual force ... one that seems to be there but isn't really there.
When something tries to fly or flow straight, through a rotating neighborhood, it ends up flying or flowing in a curved path, AS IF there were a force acting on it to make it curve. THAT apparent force is the Coriolis force.
It's what makes air, flowing away from high pressure or into low pressure, form the big rotating pressure systems on the rotating Earth.
All of the following use subjective scoring EXCEPT Archery.
<h3>What is subjective scoring?</h3>
Subjective scoring is an important and powerful tool you can use to add assessment items that are not easily scored.
Archery is scored based on point values that is assigned to the rings made on the target. Others are not point scoring sports.
Thus, all of the following use subjective scoring EXCEPT Archery.

Answer:
Explanation:
Multiply right stide by "EFG", left side will be only ABCD. Then devide right side by "ABC", leaving left side as just D. Cancel out numbers both in numerator and denominator of right
