What is an example of sustainable use? Renewable clean energy is probably the most obvious example of sustainability. Here are three examples. Solar energy: Once the sun’s electromagnetic radiation is captured, it produces electricity and heat. Wind Energy: Wind turbines convert the kinetic energy in the wind into mechanical power. Which is a sustainable practice? […]

What happens next depends on the mass of the star? About 75% of the mass of the star is ejected into space in the supernova. The fate of the left-over core depends on its mass. If the left-over core is about 1.4 to 5 times the mass of our Sun, it will collapse into a […]

Can you surf 2ft waves? A 2ft wave at 5 seconds will most likely result in small and weak waves. Swells that have a wave height of 8ft and a swell period of 22 seconds are going to be huge! However, an average swell report of 4ft at 12 seconds in Polzeath should result in […]

Why is it important to follow safety precautions before invasion? Answer: Half of all of those injuries can be prevented with proper use of safety gear and changes to the playing environment. Following sports rules can help prevent injuries, too. Lack of education and awareness about safety precautions and potential injury. What should we follow […]

How is displacement equal to area? (2). displacement=velocity × time =area of rectangle =Velocity-axis × time-axis, putting the value of velocity and time, then getting out the displacement. Why area under velocity-time graph is displacement? The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards. The […]

How many moles is 1 MgCl2 FM? 0.010502988100114 mole What is the mass of 1 mole of MgCl2? 95.211 g/mol How many atoms are in 5 moles of MgCl2? 5 moles of MgCl2 = 5.0×6.022*10²³ = 3.011*10²⁴ atoms or molecules. How many grams of aluminum are in a mole? 26.982 g How many grams are in […]

Why does the viscosity of liquids decrease with temperature? The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced. How does viscosity of liquids vary with temperature? The viscosity of liquids decreases rapidly with an […]

What are the steps for density? The five steps for determining density can be expressed in simple form as follows: measure the mass of the container, measure the volume of the liquid, measure the combined mass of the liquid and the container, determine the mass of the liquid alone and divide the mass by the […]

Which graph displays data in top to bottom fashion in storytelling with data? Answer. In most cases, Vertical bars will be used to display the data in a top-to-bottom fashion, so option D) Vertical Bar is the correct answer. These bars are normally used to show the time series data or other forms of data […]

Which is more dense Diet Coke or Coke? For example, a can of Coke Classic contains 39 grams of sugar and a can of Diet Coke contains 0.1 grams of aspartame. It takes 390 times more sugar to make a drink taste as sweet as a drink sweetened with aspartame. This additional sugar makes the […]
