What is the difference between the driving frequency and the natural frequency of an oscillator? When the oscillating system starts oscillating on its own at a frequency , then this frequency is called natural frequency. But a system oscillating due to external excitation with a frequency , then this frequency is called driving frequency. What […]
What type of rock is formed by erosion?
What type of rock is formed by erosion? Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Which type of […]

Is Nuclear Physics a good career? For academic research jobs, nuclear physics may well be a better choice, while the opportunity to design real-world solutions to power generation and medical problems is a major benefit of studying nuclear engineering. Is nuclear physics harmful to humans? Nuclear radiation can ionise chemicals within a body, which changes […]
What attributes did all the stable orbits have in common?
What attributes did all the stable orbits have in common? A stable orbit is an orbit that repeats indefinitely, without ever changing shape. After running several simulations with differing parameters, what attributes did all the stable orbits have in common? answer: All of the orbits were in the shape of an ellipse, with the orbited […]

What happens when you accidentally touch a hot object?
What happens when you accidentally touch a hot object? When a person accidentally touches a hot object, they automatically jerk their hand away without thinking. A reflex does not require any thought input. The path taken by the nerve impulses in a reflex is called a reflex arc. Reflex arc: The path taken by the […]

Which part of California has the most earthquakes?
Which part of California has the most earthquakes? Central Valley South The San Andreas fault system is the major geologic boundary between the North American and Pacific tectonic plates and passes through much of the state.
