4P + 5O2 → P4O10 How many phosphorus (P) atoms are on each side of the equation? How many oxygen atoms are on each side?
Answer:
4 p and 10 O on both sides
Explanation:
on the reactant side you can see easily that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.
On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O
They are equal on both sides so you are done.

Explanation:
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. These small differences contribute to each person’s unique physical features.

There are_____________types of wave motion-transverse ________________, and a comination of both.
This is about WAVE and this is SCIENCE
Answer:
For the first one it is Electromagnetic waves and the second one is longitudinal and transverse and water water waves (I’m sorry if I get the second one wrong for you but the first I put is right)
Explanation:
An electromagnetic wave can travel through empty space or through matter.There are 2 types of wave motion-transverse ,longitudinal and a combination of both.
What is an electromagnetic wave?The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

Which best describes the role of the water cycle? HELPPPP ASPPPPP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Circulates existing water on Earth.
The water cycle, also known as the hydrological cycle, refers to the continuous movement of water on, above, and below the Earth's surface. It involves processes such as evaporation,
condensation, precipitation, and runoff. The water cycle is responsible for circulating existing water on Earth, redistributing it from one place to another, and maintaining a constant supply of water in different forms (liquid, vapor, and ice) across various reservoirs like oceans, lakes, rivers, and the atmosphere. It plays a crucial role in balancing the Earth's water resources and supporting life on our planet.
Therefore the role of water cycle is best described by
Circulates existing water on Earth.

The difference in air pressure has increased.
The direction of the wind has changed to the south.
The speed of the wind has increased throughout the day as there has been no precipitation.
What is precipitation?Precipitation is a process in which vapor of liquid changes into small droplets.
In the day time temperature of the atmosphere is high as compare to the night, so rate of precipitation is low at the day time due to which speed of the wind has increased as compare to the night time.
Hence, option (a) is correct i.e. there is no precipitation.
