Is the rotation of the Earth slowing down? Earth’s rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth’s rotation. Atomic clocks show that a modern-day is longer by about 1.7 milliseconds than a century ago, slowly increasing the […]
What are the stages of life for a low mass star?
What are the stages of life for a low mass star? Low mass star Main Sequence. Low mass stars spend billions of years fusing hydrogen to helium in their cores via the proton-proton chain. Red Giant. When hydrogen fusion can no longer happen in the core, gravity begins to collapse the core again. Planetary Nebula. […]
How do I know if my brake booster has a vacuum leak?
What are the three ways to conserve resources?
What are the three ways to conserve resources? Three ways of conserving resources are: Resorting to alternative sources of energy which are renewable. Recycling of unwanted and waste products. By passing laws and abiding by it. Also it is important to spread awareness to bring about resource conservation. Why is it important to conserve resources? […]
Why is diffusion faster in liquid than solid?
Why is diffusion faster in liquid than solid? The rate of diffusion of liquids higher than that of solids because liquids have higher inter-particle space than solids. This leads to higher fluidity than solids as the particles in a liquid are not as closely packed as in case of solids. What is the important of […]
What happens if incidence angle is greater than critical angle?
What happens if incidence angle is greater than critical angle? When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. For any angle of incidence greater than the critical angle, light will undergo total internal reflection. What is the […]

Which is the best set up for measuring the loss of weight of a body immersed in a liquid?
What is difference between cell and tissue?
What is difference between cell and tissue? Cell and Tissue – Differences Cells are the smallest, structural and functional unit of an organism, which is characteristically microscopic. Tissues are the distinct types of material consisting of specialized cells and their products. Found in both unicellular and multicellular organisms. Which organ is a tissue? Tissues include […]
