How do you find the slope of a position time graph? Using the Slope Equation Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates […]
Is a humid subtropical climate good?
Is a humid subtropical climate good? Humid Subtropical climate is a very pleasant climate. It stays warm throughout the year. Usually Humid Subtropical is found on the east coasts of continents like you see in the map above in the North America, South America, and China. Which is hotter tropical or subtropical? The term can […]
Does rubber transfer heat?
Does rubber transfer heat? Energy, such as heat, transfers through some materials easily. These materials are called conductors. These materials include plastic, cork, wood, Styrofoam, and rubber. Thermal insulators are thus good at maintaining a consistent level of heat — whether hot or cold. Is rubber good for insulation? What makes rubber a good insulator […]
How do you describe a sine wave?
How do you describe a sine wave? A sine wave is a geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero. Is sound a sine wave? Single-frequency sound waves […]
Why do engines have low efficiency?
Why do engines have low efficiency? At low speeds, gasoline engines suffer efficiency losses at small throttle openings from the high turbulence and frictional (head) loss when the incoming air must fight its way around the nearly closed throttle (pump loss); diesel engines do not suffer this loss because the incoming air is not throttled, […]
How does a catalyst increase the rate of a reaction it decreases the enthalpy change of the reaction?
How does a catalyst increase the rate of a reaction it decreases the enthalpy change of the reaction? Explanation: Catalysts work by reducing the activation energy of a reaction, by providing an alternative reaction pathway. Because the activation energy is reduced, more reactant particles have the requisite energy to combine effectively, and the reaction rates […]
Which has more resistance 100 watt bulb or 60 watt bulb?
Which has more resistance 100 watt bulb or 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. How many volts does it take to run a light bulb? The most common voltage for […]
What is the path of a projectile motion?
Why Atomic size increases down a group and decreases across a period?
Why Atomic size increases down a group and decreases across a period? Across a period, effective nuclear charge increases as electron shielding remains constant. A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Why do energy levels increase […]
