What are the name of the properties? Property (a, b and c are real numbers, variables or algebraic expressions) 1. Distributive Property a • (b + c) = a • b + a • c 2. Commutative Property of Addition a + b = b + a 3. Commutative Property of Multiplication a • b […]

What does heat do to MS? MS causes nerves to lose their myelin sheath, making them more vulnerable to heat and temperature changes. Heat exposure can cause or heighten fatigue, numbness, blurry vision, tremor, confusion, imbalance, and weakness. This is a pseudo-exacerbation as symptoms typically dissipate once the body is cooled. Does MS get worse […]

Is force dimensionless quantity? The ratio of the internal forces to the external forces will depend upon its speed, and the viscosity of the fluid, and the size of the body. But the ratio of the internal to the viscous forces is dimensionless, so it must depend on some combination of the viscosity, speed V […]

What are the 5 levels of the Physical Activity Pyramid? Learn the 5 steps of the Physical Activity Pyramid Moderate Physical Activity. Moderate physical activity is the first step in the Physical Activity Pyramid, and it should be performed daily or nearly every day. Vigorous Aerobics. Vigorous Sport and Recreation. Muscle Fitness Exercises. Flexibility Exercises. […]

Which of the following are examples of mitigation? Other examples of mitigation measures include: Hazard mapping. Adoption and enforcement of land use and zoning practices. Implementing and enforcing building codes. Flood plain mapping. Reinforced tornado safe rooms. Burying of electrical cables to prevent ice build-up. Raising of homes in flood-prone areas. What are the priorities […]

Which of the following property of a charge can change when it moves freely in a uniform perpendicular magnetic field? The magnetic force acts perpendicular to the direction of motion of the proton. It does not change its mass and speed but changes its direction of motion. So both velocity and momentum get changed. What […]

What is an example of screw? Some examples of the uses of a screw are in a jar lid, a drill, a bolt, a light bulb, faucets, bottle caps and ball point pens. Circular stairways are also a form of a screw. Another use of the screw is in a device known as a screw […]

Which type of wave can travel in a vacuum? Electromagnetic waves How big is a 4 foot wave? The ‘Hawaiian’ system is a well established alternative to measuring the face height and tends to equate consistently to about half the face height. So a 4ft Hawaiian wave is 8ft on the face, or a couple […]

What are the 5 types of gene mutations? What kinds of gene variants are possible? Missense. A missense variant is a type of substitution in which the nucleotide change results in the replacement of one protein building block (amino acid) with another in the protein made from the gene. Nonsense. Insertion. Deletion. Duplication. Frameshift. Repeat […]

Are tongue twisters good for speech? Tongue twisters are a great way to practice and improve pronunciation and fluency. They can also help to improve accents by using alliteration, which is the repetition of one sound. They’re not just for kids, but are also used by actors, politicians, and public speakers who want to sound […]
