Motion is just movement needing a force to act upon it. Pushing and pulling are examples of forces that can sped things up or slow things down. There are two types of forces, at a distance force and contact forces.
Explanation:
4.285714268m/s/s is the answer
change in velocity divided by time equals acceleration
The variety of species in an ecosystem is known as biodiversity.
Explanation:
We need to draw position-time graph when the speed is increasing.
The slope of position-time graph gives the speed of an object.
Position means distance covered.
When the speed of an object is increasing with time. It means it is moving with increasing speed.
The attached figure shows the position -time graph when speed is increasing.
Answer:
Electrons
<h2>What are electrons?</h2>
An elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10- 19 coulombs, a mass of 9.108 × 10 - 31 kilograms, and spin of 1/2, and existing independently or as the component outside the nucleus of an atom. It can also be defined as a unit of charge equal to the charge of one electron.
