How will you increase the measure of temperature in an object? All particles are moving and have kinetic energy…. Actions that Increase Thermal Energy Explanation Raise the temperature of the object Increases the kinetic energy of the atoms or molecules Pull atoms or molecules that attract one another farther apart Increases the potential energy of […]

Can you solve physics problems? Multiply and divide the quantities until the units match the units of the answer quantity. For example, if you’re trying to find Potential Energy (kg*m2/s2) and you have the height (m), mass (kg) and gravitational acceleration (m/s2), you can match the units by multiplying the three quantities (m*kg*m/s2=kg*m2/s2). How do […]

How can I check myself for dehydration? Tests for dehydration Gently pinch the skin on your arm or stomach with two fingers so that it makes a “tent” shape. Let the skin go. Check to see if the skin springs back to its normal position in one to three seconds. If the skin is slow […]

How do you explain weather and climate? Weather can change from minute-to-minute, hour-to-hour, day-to-day, and season-to-season. Climate, is the average of weather over time and space. We hear about weather and climate all of the time. Most of us check the local weather forecast to plan our days. Which season is the most windy? Of […]

Does changing current affect voltage? To answer this question, the relationship between the voltage and current variables given must be specified. and thus that the current will change proportionally with the voltage. and thus the current will change exponentially with the voltage. Does higher voltage draw less current? If the voltage out is twice that […]

What is the first step in responding to any sports injury? Explain why the first step in responding to any sports injury is to remove the danger that lead to the injury. When someone sustains an injury while participating in sports, that indicates that something unexpected has occurred. How does compression help swelling? Compression Applying […]

What is the quotient of 20 and 5? 4 What is the quotient of 90 and 5? Subtract 40 from 40 . The result of division of 905 is 18 . How do you show 90 divided by 5? Using a calculator, if you typed in 90 divided by 5, you’d get 18. You could […]

How does the axle work? An axle is a rod or shaft that rotates the wheels and supports the weight of your vehicle. Axles are essential components of any vehicle and come in three main types: front, rear, and stub. Let’s break down the types of axle and look at how to choose the right […]

What 3 places on earth do convection currents occur? Convection currents occur within: the atmosphere – wind. the hydrosphere – ocean currents. How convection takes place in the mantle? The mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler […]

What pans can you use in a convection oven? Convection ovens work well with aluminum or light-colored metal baking pans. You can also use dark or anodized pans in your convection oven, but if you are not careful, you might end up with over-browned food. You can use a flat, thin aluminum pan to bake […]
