We don’t currently have recommendations for specific surge protectors, but you can find plenty of options for as little as $20 or less at Amazon. How long do surge protectors last? three to […]
What are some examples of chemical hazard?
What are some examples of chemical hazard? Examples of hazardous chemicals include: paints. drugs. cosmetics. cleaning chemicals. degreasers. detergents. gas cylinders. refrigerant gases. What does a toxic sign look like? The skull-and-crossbones symbol, consisting of a human skull and two bones crossed together behind the skull, is today generally used as a warning of danger […]
Do heavier objects fall faster?
Do heavier objects fall faster? Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. How do you find velocity with time and height? An object is thrown straight up from the top of a building h feet tall […]

Roll What is vehicle weight transfer caused by? When accelerating, braking or steering, the body of the car rotates in the opposite direction, which compresses the suspension on […]
What is called Turbine?
What is called Turbine? A turbine ( or ) (from the Latin turbo, a vortex, related to the Greek τύρβη, tyrbē, meaning “turbulence”) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when […]
How can 2 ohm 3 ohm and 6 ohm be connected to give an effective resistance of 4 ohm?
Is it possible for a concave lens to form a real image?
Is it possible for a concave lens to form a real image? Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). Real images are always inverted, but they can be either larger or smaller than the object. […]
Are action and reaction forces equal?
Are action and reaction forces equal? Formally stated, Newton’s third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the […]
Does speed of sound depend on humidity?
Does speed of sound depend on humidity? The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. Dry air absorbs far more acoustical energy than does moist air. This is because moist air is less dense than dry […]
What are the 3 types of schema?
What are the 3 types of schema? Schema is of three types: Physical schema, logical schema and view schema. What are the 3 types of schema theory? 2.2. 2 Three Types of Schema Schema can be classified into three types: linguistic schema, content schema and formal schema (Carrell, 1984). Linguistic schema refers to readers’ prior […]
