Is the estimated digit significant? Measurements have a certain number of significant figures or values that tell you about the measuring device. In the case of the measurement above, all of the digits are significant. The estimated value is significant because it helps define the precision of the device being used to measure. How do […]

What is the force of gravity between earth and moon? about 1.6 meters per second per second What is the force of attraction between Earth and the sun? [Given that the mass of the earth = 6 x 1024 kg, mass of the sun = 2 x 1030 kg, average distance between the two is […]

What is the ability of solid to flow? The ability of a solid rock to flow is called plasticity. Why sand can flow like a liquid yet it is not a liquid? Ans: Sand can flow like a liquid,yet it is not a liquid because both sand and cereal are granular materials. That means they […]

These are the best constellations to start with because they are visible all year long. What two stars are visible all year? […]

How does radiant energy affect the earth? Just as sunlight warms you, it warms the surface of the Earth as well. Energy from the sun is shown on the left where you see that part of the radiant energy from the sun passes through the atmosphere, is absorbed, and warms the Earth’s surface. What happens […]

How did the Bessemer process negatively impact society? It made terrible iron and steel most of the time. This was very brittle and weak and in some theories, the weak steel is what caused the Titanic to sink so quickly. It created major air pollution. What inventions came from the Bessemer process? Henry Bessemer, in […]

How do you know if net force is left or right? If two forces act on an object in opposite directions and they don’t exactly cancel, what is left over is the net force (the difference in the forces). If two(or more) forces act on an object in the same direction, the net force is […]

What are the two forms of energy quizlet? “Energy Is the Ability to Do Work.” Energy can be found in a number of different forms. It can be chemical energy, electrical energy, heat (thermal energy), light (radiant energy), mechanical energy, and nuclear energy. What are the forms and sources of energy? Different Sources of Energy […]
