What are the 5 energy transformations? Electric generator (Kinetic energy or Mechanical work → Electrical energy) Fuel cells (Chemical energy → Electrical energy) Battery (electricity) (Chemical energy → Electrical energy) Fire (Chemical energy → Heat and Light) What are the 4 ways energy can be transferred? There are 4 ways energy can be transferred; Mechanically […]
What kind of charge a glass rod acquires when it is rubbed with a piece of fur?
What kind of charge a glass rod acquires when it is rubbed with a piece of fur? By convention, we call one type of charge “positive”, and the other type “negative.” For example, when glass is rubbed with silk, the glass becomes positively charged and the silk negatively charged. What do you do with rose […]
Is Sickle Cell Anemia a deletion?
Is Sickle Cell Anemia a deletion? Sickle-cell anemia results from an A leads to T transversion in the second nucleotide of codon 6 of the beta-globin gene. We now report an uncommon beta-thalassemia gene that contains a deletion of this nucleotide. How do you know if a mutation is silent? The two amino acids are […]
Which is higher MB or GB?
What is the purpose of a scientific law quizlet?
What is the purpose of a scientific law quizlet? describes an observed pattern in nature with no explanation. it is an expectation of what scientists think will happen under the same conditions. You just studied 2 terms! What best defines a scientific law? In general, a scientific law is the description of an observed phenomenon. […]
Are people stronger at pulling or pushing?
Are people stronger at pulling or pushing? The results suggest that for our group of healthy recreationally active subjects, the upper body “pushing” musculature is approximately 1.5–2.7 times stronger than the musculature involved for pulling. Is pushing harder than pulling? Pulling is easier if you are taller than the object. Otherwise pushing would be easier. […]
Are humans made of carbon-12?
Are humans made of carbon-12? The most important structural element, and the reason we are known as carbon-based life forms. About 12 per cent of your body’s atoms are carbon. How much of the human body is carbon 12? Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium….Elemental composition […]
Is heat a scalar or vector quantity?
Is heat a scalar or vector quantity? Heat is an aggregate measure of the amount of energy stored in a system of particles (a single particle doesn’t have a temperature), but it doesn’t point in any particular direction, so it’s a scalar. What is a zero vector give an example? When the magnitude of a […]
What are the three elements of any project?
What are the three elements of any project? The triple constraint theory, also called the Iron Triangle in project management, defines the three elements (and their variations) as follows: Scope, time, budget. Scope, schedule, cost. Good, fast, cheap. What a project is not? Things that we do (or work that we do) which is routine […]
How do you maintain a triple beam balance?
How do you maintain a triple beam balance? Maintenance: Keep the triple beam balance clean at all times to maximize longevity. Most debris is easily moved using a can of compressed air. Never apply lubricants to the knives or bearings. Why is it important to zero your balance before you mass something? The mass of […]
