You can manage how the devices and wires are connected but there are no device or something to reduce it.
- deci: one-tenth.

Answer:
1. An objects position is its <u>distance</u> and <u>direction</u> from a <u>reference point</u>.
2.<u>Displacement</u> is <u>difference</u> between its <u>final</u> and <u>initial</u> positions.
Explanation:
For any position we required a reference point and the distance between the reference point and the object.
For example:
an object is 40 m away from a table.
Here the <u>distance is 40 m</u> from a reference point that is <u>a table.</u>
Displacement is the difference between its final and initial position.
For example
A person walk 20 km and then returned back 10 km.
Here distance traveled by a person is 30 km. But displacement is (20 - 10) that is the difference between final and initial position.
So displacement is 10 km.
The answer is group 18.
Explanation:
Group 18 is known as the Noble Gases. They are the most stable elements because they have a full outer shell of valence electrons, so they have no need to bond with other elements.
As accurately described by Einstein's theory of relativity, gravity is not necessarily a force, but a consequence of the curvature of space time that is caused by the uneven distribution of mass. But this could also be approximated by Newton's Law of Universal Motion. Gravity is a force acting upon two objects with masses at a certain amount of distance. So, the greater the mass, and the closer the objects are, the greater is the force of gravity. So, if you compare the gravity on Mars compared to Earth at a given distance, compare their masses. The mass of Earth is 5.972 × 10^24 kg while that of Mars is <span>6.39 × 10^23 kg. So, the gravity on Earth is much greater because Earth is heavier.
For the second question, let's base on Newton's Second Law of Motion which states: the force exerted on or by the object, is equal to its mass times acceleration. In equation, F = ma. So, if you want to increase acceleration, the force should be greater, while the mass should be lighter.</span>
