A multidimensional database (MDDB) is a type of database in which data can be viewed from multiple dimensions; commonly used with <u>MOLAP</u>.
A multidimensional database affords the ability to swiftly procedure statistics and generates solutions quickly. MDBs let users ask questions about corporations' operations and traits.
The multidimensional databases make use of MOLAP (multidimensional online analytical processing) to get admission to its statistics. They permit the users to fast get answers to their requests by means of generating and analyzing the records as a substitute quickly. The information in multidimensional databases is stored in a records dice format.
In a dimensional database, you have rows and columns, represented by means of X and Y. In a multidimensional database, you have got X, Y, Z, etc. depending on the number of dimensions in your statistics. Beneath is an instance of a 3-Dimensional statistics Array represented in a relational table and in 3-D.

Answer:
C. 0 N
Explanation:
In the absence of external forces, a body in motion will stay in motion.
F = ma
F = 6.0(0) = 0
If the acceleration is constant (negative or positive) the instantaneous acceleration cannot be
Average acceleration: [final velocity - initial velocity ] /Δ time
Instantaneous acceleration = d V / dt =slope of the velocity vs t graph
If acceleration is increasing, the slope of the curve at one moment will be higher than the average acceleration.
If acceleration is decreasing, the slope of the curve at one moment will be lower than the average acceleration.
If acceleration is constant, the acceleration at any moment is the same, then only at constant accelerations, the instantaneuos acceleration is the same than the average acceleration.
Constant zero acceleration is a particular case of constant acceleration, so at constant zero acceleration the instantaneous accelerations is the same than the average acceleration: zero. But, it is not true that only at zero acceleration the instantaneous acceleration is equal than the average acceleration.
That is why the only true option and the answer is the option D. only at constant accelerations.
