Is acceleration and velocity the same?

Is acceleration and velocity the same? Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per […]

Why uniform circular motion is not SHM?

Why uniform circular motion is not SHM? Circular motion is not a form of simple harmonic motion. SHM occurs when a particle is subjected to a force that is anti-parallel to the particle’s motion. Thus, they are very different in nature. What is epoch in SHM? An epoch, in physics, refers to the displacement acquired […]

How do you interpret Q1 and Q3?

How do you interpret Q1 and Q3? The first quartile, denoted by Q1, is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1. The third quartile, denoted by Q3, is the median of […]

How gravity affects the movement of object?

How gravity affects the movement of object? On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the […]

What cells do plants have that animals don t?

What cells do plants have that animals don t? Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not. Why are plant cells Square? Plant cells […]

What is an example of state-dependent memory?

What is an example of state-dependent memory? State-dependent memory refers to improved recall of specific episodes or information when cues relating to emotional and physical state are the same during encoding and retrieval. For example, a person may be alert, tired, happy, sad, drunk or sober when the information was encoded. … What are the […]

Who is the father of cosmology?

Who is the father of cosmology? ACHARYA KAPIL How do Cosmologists study the universe? There are two main ways in which cosmological observations support perturbed FLRW models. First, cosmologists use matter and radiation in the universe to probe the background spacetime geometry and its evolution. What is Africa cosmology? In the framework of African cosmology, […]

What is the difference between emission and absorption spectrum?

What is the difference between emission and absorption spectrum? The main difference between emission and absorption spectra is that an emission spectrum has different coloured lines in the spectrum, whereas an absorption spectrum has dark-coloured lines in the spectrum. What is basic emission? Definition of Emission The basic electronic emission occurs when heat, sunlight, electron […]

Is sodium and magnesium an ionic compound?

Is sodium and magnesium an ionic compound? There is a strong electrostatic force of attraction between these oppositely charged ions – this is called an ionic bond. The slideshow shows ionic bonds being formed in sodium chloride, magnesium oxide and calcium chloride. How do you combine ionic charges? To find the formula of an ionic […]
