force. F = force m = mass a = acceleration Newton’s Second Law. What does F mean in science? F is force, m is mass and a is acceleration. What unit is F in physics? A farad (F) is the standard unit of capacitance (C) in the International System of Units (SI). It indicates the […]

approximately equal to. ≅ (approximately equal to) What does ≅ mean IN angles? congruent anglesIn mathematics, the definition of congruent angles is “angles that are equal in the measure are known as congruent angles“. In other words, equal angles are congruent angles. It is denoted by the symbol “≅”, so if we want to represent […]

The dot product of a vector with itself is the square of its magnitude. The dot product of two vectors is commutative; that is, the order of the vectors in the product does not matter. Multiplying a vector by a constant multiplies its dot product with any other vector by the same constant. What is […]

Since we know that i×i=0=j×j and that i×j=k=−j×i, this quickly simplifies to a×b=(a1b2−a2b1)k=|a1a2b1b2|k. What is the cross product of i cap and i cap? So, i imes i=0i×i=0. Hence, the value of i cap × i cap is equal to 0. Learn more, Cross product. 1jaiz4 and 8 more users found this answer helpful. What […]

Response. i cap and j cap are the unit vectors, i cap represents unit vector in x direction while j cap represents unit vector in y direction and k cap represents unit vector in z direction. What is i cap and j cap in physics? A unit vector, i cap indicates the direction of an […]

circumflex. The circumflex (◌̂) is a diacritic in the Latin and Greek scripts that is also used in the written forms of many languages and in various romanization and transcription schemes. It received its English name from Latin: circumflexus “bent around”—a translation of the Greek: περισπωμένη (perispōménē). What is a called? A circumflex is also […]

P. probability of the data (or more extreme data) arising by chance, see P values. p. proportion of a sample with a given characteristic. q hat, the hat symbol above the q means “estimate of” What is p and P hat? P relates specifically to the overall population, and P hat relates specifically to a […]

Alternatively referred to as the squiggly or twiddle, the tilde is a character ( ~ ) on keyboards below the Esc (escape key). It is on the same key as the back quote that resembles a squiggly line. What does ∼ mean? “∼” is one of many symbols, listed in the Wikipedia article on approximation, […]

K-CAPS® vegetarian capsules provide health-conscious consumers with a natural alternative to animal-derived capsules.

Ý (ý) is a letter of Old Norse, Old Castillian, Old Astur-Leonese, Icelandic and Faroese alphabets, as well as in Turkmen language. In Czech and Slovak languages it represents a long form of the vowel y. What is the Y looking symbol? Ȳ (minuscule: ȳ) is a letter of the Latin alphabet, formed from Y […]

The ‘r hat’ is the vector r divided by the magnitude of r. So the ‘r hat’ for every point is: for the (-3,0) is ‘-i hat’, for (0,0) is zero and for (3,0) is ‘i hat’. 2. The first ‘r hat’ at point (-3,0) is 3i. The second ‘r hat’ at point (3,0) is […]

force. F = force m = mass a = acceleration Newton’s Second Law. Here, F is the net force on the mass m. W = mg. W = weight. m = mass. What does lower case F mean in physics? Force of FrictionForce of Friction: Use lower case f to represent it. Two types: Static […]

To insert a lowercase Y-Bar, hold down the Alt key and type the numbers 0563 on the keyboard’s number keypad. To type an uppercase Y-Bar, hold down the Alt key and type the numbers 0562. When you release the Alt key, the Y-Bar symbol inserts in the slide. How do you write y bar? Ȳ […]

• ‘i’ is the horizontal component. • ‘j’ is the vertical component. What is the i and j in physics? The i,j notation A unit vector is a vector of length 1, in Cartesian co-ordinates the unit vectors along the axis are denoted by i and j respectively. Any two-dimensional vector can be written in […]

Informally, it means “approximately”, “about”, or “around”, such as “~30 minutes before”, meaning “approximately 30 minutes before”.
