What is the relationship between rolling static and sliding friction? Static, sliding, and rolling friction occur between solid surfaces. Static friction is strongest, followed by sliding friction, and then rolling friction, which is weakest. Fluid friction occurs in fluids, which are liquids or gases. What is the cause of friction What is the difference between […]
What happens when a solid turns into a liquid?
What happens when a solid turns into a liquid? When a solid is heated the particles gain energy and start to vibrate faster and faster. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are […]

How does the eye respond to bright light?
How does the eye respond to bright light? In bright light, it contracts. Light detected by the retina of your eye is converted to nerve impulses that travel down the optic nerve. Some of these nerve impulses go from the optic nerve to the muscles that control the size of the pupil. More light creates […]
Which letter has the most water?
Which object experiences the greatest acceleration?
Which object experiences the greatest acceleration? Car A Which vehicle experiences the greater change in acceleration? (c) Mass and acceleration are inversely proportional to each other. Therefore, car experiences greater acceleration due to its smaller mass. (d) Due to its smaller mass or opposition to the force exerted on it, the car is likely to […]
What is the characteristics of other planets in the solar system?
What is the characteristics of other planets in the solar system? The solar system is host to two broad categories of planets. The four closest to the sun — Mercury, Venus, Earth and Mars — are the terrestrial planets. They have rocky surfaces enclosed by relatively shallow atmospheres. The gas and ice giants — Jupiter, […]
What type of reaction is magnesium with hydrochloric acid?
What type of reaction is magnesium with hydrochloric acid? Oxidation – Reduction. Adding magnesium metal to hydrochloric acid produces hydrogen gas. The magnesium dissolves to form magnesium chloride, MgCl2. What type of reaction is MgCl2? Magnesium (Mg) combines with chlorine (Cl2) to form a new product as magnesium chloride (MgCl2). Therfore its a combination reaction […]
What is the formula for energy transformation?
What is the formula for energy transformation? An object that has potential energy has energy by virtue of position and is related by the Newtonian equation PE=mgh (where m equals mass in Kg, g the acceleration due to gravity—approximately 9.8 m/s2 near Earth’s surface—and h equals height in meters). Is a potato a bulb? Potatoes […]
What is the price elasticity of supply Can you explain it in your own words?
What is the price elasticity of supply Can you explain it in your own words? Price elasticity of supply measures the responsiveness to the supply of a good or service after a change in its market price. According to basic economic theory, the supply of a good will increase when its price rises. Conversely, the […]
