What is the relationship between half-life and decay constant? This shows that the population decays exponentially at a rate that depends on the decay constant. The time required for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life, T1/2, and the decay constant is given […]
What is the weakest of the four fundamental forces?
What is the weakest of the four fundamental forces? Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity. Because they both have mass, the two protons exert gravitational attraction […]
What are the two factors of gravity and how do they affect gravitational pull?
What are the two factors of gravity and how do they affect gravitational pull? Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them. Objects that […]
Does friction depend on surface area?
Does friction depend on surface area? Friction is a contact force when two surfaces interact. Notice that both of these friction formulas ONLY depend on the coefficient of friction and the normal force. It does not depend the area of contact, it doesn’t depend on the sliding speed. Is friction dependent on mass? Friction DOES […]
Which Cannot be separated physically?
Which Cannot be separated physically? What is a Pure Substance? It is something which cannot be divided into parts by physical means, as it’s all made up of the same thing. Pure substances are either elements or compounds. Elements can NOT be separated into other types of matter (physically or chemically). What are the examples […]
What state has lowest barometric pressure?
What state has lowest barometric pressure? Honolulu, Hawaii Is 30 a high barometric pressure? A barometer reading of 30 inches (Hg) is considered normal. Strong high pressure could register as high as 30.70 inches, whereas low pressure associated with a hurricane can dip below 27.30 inches (Hurricane Andrew had a measured surface pressure of 27.23 […]
How do you graph an inequality with two variables?
How do you graph an inequality with two variables? To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality. If given a strict inequality, use a dashed line for the boundary. If given an inclusive inequality, use a solid line. […]
Can I self refer to an endocrinologist?
Can I self refer to an endocrinologist? When to See an Endocrinologist A primary care provider will determine if you need to see an endocrinologist and can write you a referral. The PCP may be able to diagnose and treat your condition themselves, without referring you to specialized care. What tests does an endocrinologist do? […]
What is an example of social construct?
What is an example of social construct? An example of a social construct is money or the concept of currency, as people in society have agreed to give it importance/value. Strong social constructs rely on the human perspective and knowledge that does not just exist, but is rather constructed by society. Is disability socially constructed? […]
Does oxygen follow octet rule?
Does oxygen follow octet rule? Octet rule: The concept that compounds containing carbon, nitrogen, oxygen, and fluorine are more stable if these atoms have eight valence electrons. When one of these atoms has less than eight valence electrons it has an open octet. Every carbon, nitrogen, oxygen, and fluorine atom in this molecule has a […]
