Where does energy go when something breaks? In all real collisions, energy is lost when it hits the ground, some of it going into creating a sound and some going into deforming or even breaking the object apart. When would a falling object have the most kinetic energy? As an object falls under the influence […]
Why do we always have to include uplift with erosion?
Why do we always have to include uplift with erosion? Description. Erosional processes and rates of uplift strongly influence the overall shape of eroding landscapes. Uplift of a mass above base level increases the potential energy of the land. Uplift steepens stream profiles, energizing the streams, which then cut into the land mass. How does […]
What is a modified block style letter?
What is a modified block style letter? A modified block style letter is a common format used when writing a business letter. It varies slightly from a block style letter with the major difference being the placement of the return address, date, and complimentary closing. How do you write a modified block letter? In a […]
What affects the strength of van der Waals forces?
What affects the strength of van der Waals forces? Number of Electrons Held by the Atoms/Molecules The greater the number of (instantaneous) dipoles formed, the greater the strength of the Van der Waals force. What are the three types of van der Waals forces? van der Waals forces may be classified into three types: electrostatic, […]
What happens to bimetallic strip when heated?
What happens to bimetallic strip when heated? When this bimetallic strip is heated, the brass expands more than the steel and the strip curves with the brass on the outside. If the strip is cooled, it curves with the steel on the outside. Bimetallic strips are used as switches in thermostats. Why is a bimetallic […]
Does force equal mass times velocity?
Does force equal mass times velocity? The first equation states that a Force is equal to Mass times Acceleration, or Newton’s second law of motion. The second one states that Momentum (P) is equal to Mass times Velocity. You can see that the difference lies between velocity and acceleration: acceleration is the rate of change […]
How would you change the distance between two charged particles?
What do you do in bad weather boating?
What do you do in bad weather boating? Staying Safe in a Storm All of your passengers should be wearing lifejackets. Maintain your forward movement, but reduce your speed. Ensure that your navigation lights are on. Get your passengers to sit along the centreline of your boat in order to stabilize it and prevent them […]
What are the effects of climate change on ecosystems?
What are the effects of climate change on ecosystems? Ecosystem perturbations driven by climate change have direct human impacts, including reduced water supply and quality, the loss of iconic species and landscapes, distorted rhythms of nature, and the potential for extreme events to overwhelm the regulating services of ecosystems. How can humans change ecosystems? Humans […]
Why do scientists believe the Abert and Kaibab squirrels are examples of speciation?
Why do scientists believe the Abert and Kaibab squirrels are examples of speciation? Explain why scientists believe the Abert’s and Kaibab squirrels are examples of speciation. -The Kaibab Squirrel gives us one nice example of evolution occurring due to geographic isolation. One population of squirrels had become two separate populations that could no longer interbreed, […]
