What is the relationship between enzymes and activation energy? Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. What happens when activation energy is lowered? Fortunately, it’s possible to lower the activation […]
Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb?
Which one has a higher electrical resistance a 100 watt bulb or a 60 watt bulb? A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high. Which one is having lesser resistance a 220v 60W bulb or […]
What is the process of an action potential?
What is the process of an action potential? When a nerve impulse (which is how neurons communicate with one another) is sent out from a cell body, the sodium channels in the cell membrane open and the positive sodium cells surge into the cell. Once the cell reaches a certain threshold, an action potential will […]

Which statement is an electrolyte?
Which statement is an electrolyte? Which statement describes an electrolyte? An electrolyte conducts an electric current as a solid and does not dissolve in water. When an electrolyte dissolves in water, the resulting solution conducts an electric current. Do electrolytes dissolve in water? Substances that dissolve in water to yield ions are called electrolytes. Electrolytes […]
What is r in ideal gas law?
Can a cloud freeze?
Can a cloud freeze? Clouds do freeze in extreme temperatures. Cirrus clouds, which are the highest, are not liquid droplets, but rather ice crystals. What confuses me is why you believe that freezing to solid crystals would make them fall from the sky. The ice crystals do not weigh any more than water droplets would. […]
How long does it take a star to return to the same position in the sky as it was the night before?
How do you find maximum velocity?
How do you find maximum velocity? Using Calculus If acceleration is positive to the left and negative to the right, the point is a maximum velocity. In the example, a=3cos(t) is positive just before t=π /2 and negative just after, so it is a maximum; however, 3π/2 is a minimum because a=3cos(t) is negative just […]
