Answer:
20.65 m/s
Explanation:
You are gonna wanna use a calculator for this one
so we will write all the known variables:
h = 15.6 m
initial velocity (u) = 10.7 m/s
acceleration (a) = 10 m/s/s (gravity)
From the third equation of motion:
<em>v² - u² = 2ah</em>
<em>v² - (10.7)² = 2(10)(15.5)</em>
<em>v² - (10.7)² = 312</em>
<em>v² = 312 + 114.49</em>
<em>v² = 426.49</em>
v = 20.65 m/s
Velocity of the plane relative to the air = +400.0 m/s
Velocity of the air relative to the ground = -35.0 m/s (negative because it's moving opposite to the eastward direction)
Velocity of the plane relative to the ground = (velocity of the plane relative to the air) + (velocity of the air relative to the ground) = 365.0 m/s to the east
Answer:
An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules. Many biological processes are devoted to breaking down molecules into their component atoms so they can be reassembled into a more useful molecule.
Atomic Particles
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged). Atoms have different properties based on the arrangement and number of their basic particles.
The hydrogen atom (H) contains only one proton, one electron, and no neutrons. This can be determined using the atomic number and the mass number of the element (see the concept on atomic numbers and mass numbers).
