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 […]

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?

Why is Jupiter so huge?
Why is Jupiter so huge? The traditional view is that Jupiter first formed a rocky core, several times the size of Earth, which then attracted a still larger outer envelope of gas. This process is known as “accretion.” Boss believes that gas giants such as Jupiter may have formed as a result of instability in […]
What are the two main reasons air pressure changes?
What are the two main reasons air pressure changes? Although the changes are usually too slow to observe directly, air pressure is almost always changing. This change in pressure is caused by changes in air density, and air density is related to temperature. What are the two factors influencing the movement of air or wind? […]
