Is pressure a vector or scalar quantity?I know force is a vector quantity since it is defined as a pull or a push one object exerts on another.if so, why pressure, which can be calculated using the relationship 'pressure = force over area' is a scala It is a pressure A unit vector parallel to vector (2,-3,6) is vector?答案选（-0.29,0.43,-0.86） vector a = new vector(50);是什么意思 It is a pressure是什么意思?pleasure is the vector a=i+2J-2ka veit vector?if not find the unit vector having the same direction as a? is the vector a=i+2J-2ka veit vector?if not find the unit vector having the same direction as a?字母上面是向量~ Love is a kind of pressure 什么意思 .Let A and B be vector subspaces of a vector space V .The intersection of A and B,A ∩ B,is the.Let A and B be vector subspaces of a vector space V .The intersection of A and B,A ∩ B,is the set {x ∈ V | x ∈ A and x ∈ B}.The union of A and B, Don’t be afraid of pressure.Remember that pressure is what turns a lump of coal into a diamond. 线性代数相关证明 Suppose that,for a given matrix A,there is a nonzero vector x such that Ax=0.Show that there is also a nonzero vector y such that A*y=0 下列每个 vector 对象中元素个数是多少?各元素的值 是什么?(a) vector ivec1;(b) vector ivec2(10);(c) vector ivec3(10,42);(d) vector svec1;(e) vector svec2(10);(f) vector svec3(10,hello); Vector ,which is directed along an x axis,is to be added to vector ,which has a magnitude of 7.4 m.The sum is a third vector that is directed along the y axis,with a magnitude that is 4.3 times that of .What is the magnitude of 帮个忙~..如果解 翻译 1.for vectors,mean(x) return the mean value 2.for matrices,mean(x) is a row vector 这里的insert是什么意思Inserting anywhere but at the end of a vector is an expensive operation.句子说的是 插在anywhere比较enpensive 还是插在end of a vector比较expensive? 英语翻译Boiling is a rapid type of evaporation in which vapour bubbles,forming in the liquide,expand rapidly because their pressure is high enough to overcome atmospheric pressure. Blood pressure is subject to blood pressure regulation.如何翻译? pressure pressure
