What is the acceleration in a straight line? The rate of change of the velocity of a particle with respect to time is called its acceleration. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one […]
How is energy from volcanoes tapped as source of electricity?
How is energy from volcanoes tapped as source of electricity? Energy from volcanoes is trapped as source of electricity because of the heat from the Earth’s interior that warms up water energy from volcanoes tapped as source of electricity. And this causes the Geothermal Energy. The energy that is coming from earth or the substance […]
Who proposed dynamo theory?
Who proposed dynamo theory? Walter M. Elsasser What evidence supports the dynamo theory? Earth’s crust core contains a large amount of iron and nickel is the evidence of the dynamo theory. What is meant by dynamo effect? Dynamo Effect. The dynamo effect is a geophysical theory that explains the origin of the Earth’s main magnetic […]
What is the purpose of a distance-time graph?
What is the purpose of a distance-time graph? A distance-time graph shows how far an object has travelled in a given time. It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. What is the distance between two nodes in a graph? In the […]
What is the loss of traction most difficult to identify quickly?
What is the loss of traction most difficult to identify quickly? Signs of hydroplaning – this is the most difficult loss of traction for a driver to recognize • Water standing on the roadway. How do you fix loss of traction? If You Lose Traction Gently reduce pressure on brakes – if on ice, push […]
What is the coefficient of volume expansion?
What is the coefficient of volume expansion? An object of volume V expands to V+ΔV when temperature is increased by ΔT, then volume expansion coefficient αv is given by. αv = (ΔV/V) / ΔT. What is a coefficient of thermal expansion? THE COEFFICIENT OF LINEAR thermal expansion (CTE, a, or a1) is a material property […]
What does B horizon mean?
What does B horizon mean? : a subsurface soil layer that is immediately beneath the A horizon from which it obtains organic matter chiefly by illuviation and is usually distinguished by less weathering. What is another name for C horizon? Alternative Title: soil horizon. What does C horizon mean? : the soil layer lying beneath […]
How many ohms does a 9-volt battery have?
How many ohms does a 9-volt battery have? Batteries will always have some resistance. Though the internal resistance may be or appear low, around 0.1Ω for an AA alkaline battery, and about 1Ω to 2Ω for a 9-volt alkaline battery, it can cause a noticeable drop in output voltage if a low-resistance load is attached […]
