What holds our solar system together?
What holds our solar system together? The Sun is a yellow dwarf star, a hot ball of glowing gases at the heart of our solar system. Its gravity holds the solar system together, keeping everything – from the biggest planets to the smallest particles of debris – in its orbit. What best describes the formation […]

How can you relate intermolecular forces in real life situation?
How can you relate intermolecular forces in real life situation? Water moves through a xylem tube which is an incredibly small space for substances to pass through. However, through capillary action water can move simply by the ability for the water to cling to the plant surface walls. As a result all the plants you […]

Why is it called a half-life?
Why is it called a half-life? It’s easy misinterpret half-life to mean “one half of the time it takes for whatever atoms you’re looking at to decay,” but it actually means “the length of time it takes for one half of the atoms you’re looking at to decay.” The measurement is useful in radiometric dating, […]
Is tension or compression negative?
Is tension or compression negative? The resultant forces at the ends must be equal in magnitude and opposite in direction, along the line of the joints of the member. These forces are called axial forces. The member is said to be in compression if T is negative (ie, the forces at each end are toward […]
What is the relation between density and volume?
What is the relation between density and volume? Volume is the three-dimensional space enclosed by the closed surface. Density is mass per unit volume. The relation between density and volume is directly proportional. That is any change in volume will result in the change in its density and vise-versa. Is denser lighter or heavier? Students […]
