Chemistry is a field of science deals with chemicals, reactions, and their structure. Chemistry is the discipline in which geology, material, and nutrition are studied.
The field of science deals with the substances of matter its composition and the checking of their reactions and property of a chemical reaction.
The field of science interact with the physical structure of the earth, and history of the earth's surface, and the processes already done.

The speed of electron be 183.73 m/s.
The energy held within an object is known as potential energy. There are several different types of potential energy, including gravitational potential energy, elastic potential energy, and electric potential energy. An object's energy as a result of the overall charge it contains is known as its electric potential.
Given parameters:
Distance between proton and electron: d = 0.03 m.
Let, at that point the speed of the electron be v.
So from conservation of energy:
Kinetic energy of electron + potential energy of electron = 0
1/2×mv² - 1/(4πε₀)(e²/d) = 0
⇒v = √(2e²/m(4πε₀)(d))
= √( 2 × (1.6 ×10⁻19)²× 9 × 10⁹/9.1093837 × 10⁻³¹×0.03) m/s
= 183.73 m/s.
The speed of electron be 183.73 m/s.

Neon gas
Arrange the substances in the table from the MOST to the LEAST ordered particle arrangement
A)
wood, water, neon gas
B)
wood, neon gas, water
water, wood, neon gas
D
water, neon gas, wood
Answer:
I think the correct answer from the choices listed above is option A. The correct arrangement of the substances according to the most to the least ordered particle arrangement should be wood, water and neon gas. Wood should be the first since it is solid which has the most ordered structure as compared to the liquid and a gas. The neon gas is the last since as a gas it has the least ordered structure.
Answer:
A) wood, water, neon gas
Explanation:
wood, water, neon gas.
The particles of solids have an arrangement that is highly ordered and regular. Liquids have an arrangement that is less ordered, and the particle arrangement in gases is the least ordered and regular of the three states of matter.
tell me if im wrong .... hope this helps :)
A. They are summaries of many scientists' work.
B. They include the opinions of many scientists.
C. They contain more details about the experiment.
D.They are always easier to read.
One advantage of using primary sources when doing research on an
experiment is they contain more details about the experiment. The correct option is C.
Primary sources are the one which are first hand sources. They are more reliable, so they are more reliable and detailed about the experiment.
Primary sources are the sources which produce their own energy to let other objects emit the same. Just like, Sun, it has has its own light and heat energy. It is reliable and can be experimented with more details.
Thus, the correct option is C.

Answer : Option D) Fixed-position pulleys are connected to a fixed point and do not move.
Explanation : As the name suggests the moving pulleys move freely whereas the fixed pulleys as per their name is attached to a fixed position and at a fixed point and they can not move freely.
Movable pulleys are ones which has one part of the rope attached to a fixed object, like a bar or a beam. Whereas when both the parts of a rope are attached to a fixed object, this is called as a fixed pulley.
