Is sea water renewable or nonrenewable? That’s because life in the oceans is a renewable resource. Unlike oil or other mineral resources, which come in limited supplies, ocean life renews itself. Can a resource be renewable and nonrenewable? Explanation Renewable resources cannot be replaced in our lifetime. Solar power, natural gas, and wood are all […]
Is energy conserved when a marble rolls down a ramp?
Is energy conserved when a marble rolls down a ramp? Ignoring frictional losses, the total amount of energy is conserved. So when you roll a ball down a ramp, it has the most potential energy when it is at the top, and this potential energy is converted to both translational and rotational kinetic energy as […]
Which is the most reactive gas?
Which is the most reactive gas? Hydrogen Why noble gases are not reactive? The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions. atoms of group 0 elements […]
What evidence supports the existence of a very massive black hole at the center of our galaxy?
What evidence supports the existence of a very massive black hole at the center of our galaxy? Astronomers have found convincing evidence for a supermassive black hole in the center of our own Milky Way galaxy, the galaxy NGC 4258, the giant elliptical galaxy M87, and several others. Scientists verified the existence of the black […]
What is split light used for?
What is meant by code coverage?
What is meant by code coverage? Code coverage is the percentage of code which is covered by automated tests. Code coverage measurement simply determines which statements in a body of code have been executed through a test run, and which statements have not. Which of the following is used for code coverage? CTC++, as its […]
What is the biggest scorpion that ever lived?
What is the biggest scorpion that ever lived? sea scorpion Are Scorpions older than dinosaurs? Scorpions are a very old animal group, turning up in the siluarian period (more than 400 million years go). They were around long before the dinosaurs. We know very little about these primitive scorpions, but it is possible that they […]
What are the 7 changes of state?
What are the 7 changes of state? Common changes of the state include melting, freezing, sublimation, deposition, condensation, and vaporization. These changes are shown in the figure given below. What are examples of changes of state? 1 Answer. Phase changes include vaporization, condensation, melting, freezing, sublimation, and deposition. Evaporation, a type of vaporization, occurs when […]
Why is field inside a conductor zero?
Why is field inside a conductor zero? The electric flux is nothing but the rate of flow electric field through the given area. Since the electric charges are not present inside the conductors, the electric field will remain zero. Why is the electric field inside a charged sphere zero? It follows that: The electric field […]
How do you solve uniform acceleration?
How do you solve uniform acceleration? Summary Acceleration that does not change in time is uniform, or constant, acceleration. The equation relating initial velocity, final velocity, time, and acceleration is vf=vi+at. How do you find acceleration? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a […]
