Define process equation |
|
Answer» gebra, an equation can be defined as a mathematical statement consisting of an equal symbol between TWO algebraic expressions that have the same value.☀️The process of finding the value of the VARIABLE is called SOLVING the equation.☀️There are THREE major FORMS of linear equations: point-slope form, standard form, and slope-intercept form.☀️An equation is written as two expressions, connected by an equals sign ("="). ☀️The expressions on the two sides of the equals sign are called the "left-hand side" and "right-hand side" of the equation. , consisting of just one term. ☀️The unknowns are x and y, and the parameters are A, B, and C.A scientific equation is a mathematical equation. ☀️The most important part of an equation is the equal (=) sign. |

If a displacement time graph is drawn then it will specifically represent speed please answer fast |
|
Answer» TrueExplanation:The formula for speed = total distance / timewhereas displacement = distance ,So the graph will REPRESENT the speed of the object .here is the ANSWER from google too - A SLOPING line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or GRADIENT of the line, is equal to the velocity of the object. The STEEPER the line (and the greater the gradient) the faster the object is moving. |

Answer» Home»Forum»Mechanics»a particle is describing uniform circular...a particle is describing uniform circular motion in the anti clockwise sense such that its time period of revolution is T. at t=0 the particle is observed to be at A. if B1 be the angle between acceleration at t= T/4 and average velocity in the time interval 0 - T/4 and B2 be the angle b/w acceleration at t= T/4 and the CHANGE in velocity in the time interval 0-T/4, then the value of B1 and B2 are?6 years agoAnswers : (5)your question seems wrong... B1 for T/4 and B2 also for T/4..?6 years agoDisapprovedno B1 is the angle b/w acceleration and average velocity but B2 is the angle b/w acceleration and change in velocity6 years agoYour question really seems wrong. B2 is the angle between acceleration and change in velocity what do you mean by change in velocity. Change in velocity is called acceleration. So according to you B2 will be the angle at time T/4 between acceleration and acceleration. Correct your question.6 years agoDisapprovedits correct ND in this ques by change in velocity they mean velocity at t=T/4 - velocity at t=0... thats how i interpreted it.......nd RATE OF change in velocity is called acceleration6 years agohere VAVG = displacement/time ... as time is a scalar and others are vectors.. their direction is same... now displacement and acceleration make an angle of 135 degrees..... (by using angle between vectors..) now change in velocity is V2-V1 ... here V2 & V1 have same MAGNITUDE but r perpendicular... hence V2-V1 makes 45 degrees with V2 , which is perpendicular to acc. hence angle b/w V2-V1 & acc. is 45 degrees |
