Why is force inversely proportional to square of distance? This is because the force acts uniformly in all directions from the point source and conserves the energy over the entire surface surrounding the point object. Since the surface is a sphere the area of the sphere is given as 4πr2. What is the inverse square […]
What are soil remediation techniques?
What are soil remediation techniques? Remediation techniques which have been commonly used include: containment, pump-and-treat, extraction, stabilization/solidification, soil washing, air stripping, precipitation, vitrification, thermal desorption and biological remediation. What are the methods of soil remediation? Options for treating contaminated soil include: Biological treatment/bioremediation uses bacteria to break down substances in the soil. Chemical oxidation converts […]
What is the evidence that volcanic activity can affect global temperatures?
What is the evidence that volcanic activity can affect global temperatures? The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics […]
Is friction useful in rowing?
What keeps the heat in Earth?
What keeps the heat in Earth? There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive […]

What are good writing strategies?
What are good writing strategies? Listen and respond to guidance offered while producing your work. Keep focused on your question or task – keep asking yourself whether any material you plan to include is really relevant. Be clear, concise and to the point in what you write. Present your ideas in a clear and logical […]
What is not affected by the force acting on an object?
What is not affected by the force acting on an object? A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the interaction between two objects they exert a force on each other, these exerted forces are equal […]

An elliptical galaxy is a galaxy that has the shape of an ellipse. It is […]
Why does the acceleration stay constant?
Why does the acceleration stay constant? Sometimes an accelerating object will change its velocity by the same amount each second. This is referred to as a constant acceleration since the velocity is changing by a constant amount each second. An object with a constant acceleration should not be confused with an object with a constant […]
