What net force is needed for a 1500 kg car? We assume the acceleration is constant, so we can use the kinematic equations, Eqs. 2-11, to calculate it. vo= 100 km/h FIGURE 4-6 Example 4-3. The net force required is then SF = ma = (1500 kg)(-7.1 m/s) = -1.1 X 10^N. How much force […]

What best describes the role of genes in evolutionary classification? What best describes the role of genes in evolutionary classification? Certain genes are derived characters that can be used to define clades. The cladogram shown below represents the evolutionary relationship among five modern species, as well as five derived characters of the lineages. Do humans […]

What are the 3 types of investigations? Scientists use three types of investigations to research and develop explanations for events in the nature: descriptive investigation, comparative investigation, and experimental investigation. What are the 3 kinds of variables? There are three main variables: independent variable, dependent variable and controlled variables. How do you identify variables in […]

What is the typical duration of mendix Sprint? Sprint and Story Management When you are rapidly developing apps with Mendix, sprints are 1-2 week development cycles – not the typical 3-4 weeks. Once you create your first sprint, you can add stories and tasks and assign them to individuals. What does it mean if mendix […]

How do humans use surface water? The main uses of surface water include drinking-water and other public uses, irrigation uses, and for use by the thermoelectric-power industry to cool electricity-generating equipment. Why is surface water important? Alongside being used for drinking water, surface water is also used for irrigation, wastewater treatment, livestock, industrial uses, hydropower, […]

How do you treat tight calf and Achilles? Wall Stretch Place the toes of the front foot up the wall and press the heel into the floor (this is the leg that will be stretched). Lean into the stretch and perform it with a straight and bent knee just as the previous stretch to target […]

How do all living beings depend on the atmosphere for their survival class 7? All living beings depend on the atmosphere for their survival. Atmosphere provides them the air they breathe. It protects them from the harmful effects of the sun’s rays. Without its protection, they would be baked alive by the heat of the […]

What are the 3 primary ways of using bioenergy? In fact, the big advantage of bioenergy is that its use reduces the use of such non-renewable energy sources. There are three major ways in which the energy in plants is utilized: direct burning, conversion to gas, and conversion to alcohol. What is the main fuel […]

How do you find distance with time and mass? The mass amount does not change the formula because all objects accelerate at the same rate when falling downward. Take the final velocity/speed amount, or 0.99 meters per second, and plug it into the basic formula for speed: speed = distance/time. How do you calculate mass […]
