Answer: The acceleration of the object will be 4000
Explanation:
According to second law of motion:
Unit of the force:
According to question we have :
Force = 20 N
Mass of the object = 5 g = 0.005 kg (1 kg =1000 g)
Acceleration = ?
By using the second law of motion = F= ma
The acceleration of the object will be 4000
80 joules
Given:
A 2 kg mass is held 4 m above the ground.
Let us write as follows:
Question:
What is the approximate potential energy (PE) due to gravity of the mass with respect to the ground?
The Process:
We will solve the problem of gravitational potential energy.
Gravitational potential energy = mgh, where m represents mass (in kg), g represents Earth's gravitational field (10 N kg⁻¹), and h represents the height change (in m).
Let us find out the approximate potential energy due to the gravity of the mass concerning the ground on the Earth.
Gravitational potential energy = (2 kg)(10 N kg⁻¹)(4 m)
Thus, gravitational potential energy equal to 80 joules.

Amino acids are the building blocks of proteins. When amino acids combine, they form peptide bonds resulting in the formation of peptides or proteins. Proteins are the type of molecule formed from amino acids.
Amino acids are organic compounds that consist of an amino group a carboxyl group and a side chain attached to a central carbon atom.
When two or more amino acids come together, they undergo a condensation reaction, also known as a dehydration synthesis reaction. During this process, the amino group of one amino acid reacts with the carboxyl group of another amino acid, resulting in the formation of a peptide bond.
As more amino acids are added to the chain, it continues to grow, and the resulting molecule is known as a polypeptide.
Proteins are large, complex molecules that play crucial roles in various biological processes.
Therefore, amino acids combine through peptide bond formation to create polypeptides, and when polypeptides fold into a specific structure, they become proteins.
