The answer to the question is Carbon dioxide
D. All of its wavelengths are harmful
This is false, because a lot of electromagnetic radiation (such as visible light we see with our eyes) is not harmful.
Answer:
Polar
Explanation:
In a water molecule, the oxygen atom is bigger and has a greater pull on the electrons than the hydrogen atoms do. This makes the molecule polar.
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.
