AI Thread Summary
To find the value of m that makes the volume of the parallelepiped equal to 24, the scalar triple product of the vectors must be calculated. The volume is determined using the formula V = |u · (v × w)|, where u, v, and w are the given vectors. The vectors provided are (2i + 3j + 4k), (0i + 4j + 0k), and (0i + 5j + mk). The calculation involves determining the cross product of the second and third vectors, followed by the dot product with the first vector. Solving the resulting equation will yield the required value of m.

Homework Statement


The edges of a parallelopiped are given by the vectors (2î + 3j^+ 4k^), 4j^ and (5j^ + mk^). What should be the value of m inorder that the volume of the parallelopiped be 24?

Homework Equations

The Attempt at a Solution


Volume of the parallelopiped is the scalar triple product of three vectors. I want to know the formula or method of finding dot product of three vectors.

The scalar triple product is not a dot product of three vectors, it is ##\vec u \cdot (\vec v \times \vec w)##.

Thank You.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
