Answer:
Law 2
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Hence, Law 2 might require you to do some math calculations.
For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Given the following data;
Mass = 20kg
Acceleration = 0.5m/s²
To find the force;
Force = mass * acceleration
Substituting into the equation, we have;
Force = 20 * 0.5
Force = 10 Newton.
Answer:
A
Explanation:
The answer is Wingless I think.
The correct option is this: HAS THE CLAIM BEEN TESTED NUMEROUS TIMES BY MORE THAN ONE SCIENTISTS.
For a claim to be accepted has been valid in the science world, it must have been tested several times by many scientists who obtain the same results. Having a uniform result about a phenomenon is usually considered an important factor when examining the validity of a claim.
Answer: Prokaryotes lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found during a central a part of the cell called the nucleoid. The plasma membrane of a prokaryote acts as an additional layer of protection, helps maintain cell shape, and prevents dehydration.
Explanation:
Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
