Answer:
Option (c)
Explanation:
Parallel arrays are those arrays which are used to store some records which needs more than one array to hold a entry but are interrelated and should be accessed by same index number. As they are of different data types so can't be stored as multi-dimensional array or matrix. Then parallel array comes to rescue. For example : Details of a student.
Name, age and ID of a student needs to be stored. So, three arrays can be made and each entry should be accessed by same index number.
Dichotomous variables
Explanation:
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data item.
Answer:
True
Explanation:
When an object is falling under the influence of gravity, the distance of fall as a function of time is given by:
D(t)=ut + 1/2 * a * t^2
Where
u = initial velocity of the object ( = 0 in this case as the object is falling only under gravity),
a = acceleration of the falling object = g = 9.8 m/s^2 which represents the acceleration due to gravity.
Simplifying,
D(t) = 1/2 * g * t^2
