The force that holds two atoms together is called a chemical bond.

What is a chemical bond

A chemical bond is a force of attraction that holds two or more atoms together to form a stable molecule or compound. Atoms consist of a positively charged nucleus containing protons and neutrons, surrounded by negatively charged electrons. In order to achieve a stable electronic configuration, atoms can undergo chemical bonding to fill their outermost electron shells.

Chemical bonds play a vital role in determining the physical and chemical properties of substances. The strength and type of bond between atoms influence factors such as boiling points, melting points, solubility, and reactivity. Understanding chemical bonds helps explain how different substances interact and form new compounds.

Which of the following would occur if the Thrush population was to suddenly decrease?



a
The population of Eagles would increase
b
The population of Eagles would decrease
c
The population of Dragonfly would decrease
d
The population of corn would increase

Answers

Answer- B

Reasoning: Since Eagles directly eat Thrush, their populations would decrease.

The other answers are wrong because with the first choice, Eagles would not increase in population if one of their food sources were removed. For the third choice, Dragonflies wouldn’t increase. Since Thrush eat Dragonflies, the disappearance of Thrush wouldn’t hurt the population of Dragonflies. Lastly, The last option is wrong because corn isn’t reliant on animals to survive. If Thrush disappear, corn will not be affected. This leaves B. to be the answer.

Newton's second law of motion is F = ma.

A net force of 60 N north acts on an object with a mass of 30 kg. Use Newton's second law of motion to calculate the amount of acceleration the object will experience. Then explain how the amount of acceleration will change if the net force or the mass of the object increases.

Answers

Answer:

this was asked before here the screenshot

If F=ma then A= f/m so 60 divide 30 = 2
If force increases then acceleration will increase too example 90/30=3
But if mass increases acceleration decreases example 60/60 =1

There were days, early in the summer like this one, where it seemed there was more water in the air than in the bay. We had beached the boat and stepped out on the recently cleared spit of land. The ground had a light dusting of white sand over an under layer of dried black mud. It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste.

Our beach, our summer home, had been a fishing camp for as long as anyone living could remember. The oldest stories told of travelers coming down to the edge of the sea, lining up to fill their wagon beds with salted fish to take back home. Old decaying cabins still lined the beach. Rotting nets, hung out to dry in the last century, decorated their weathered walls. Their broken faces spun stories in our minds. The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds. The bounty of the sea lightened everyone's hearts, and the smell of roasting fish filled the damp air. Women fanned themselves from wagon seats. Children splashed in the shallow edges of the bay.
