If the distance of an object is determined from the relation: d = a X + b Y Where: (d) is the distance covered by the body. (a)is a physical quantity which has a dimensions (L T^-1). (b)Is a physical quantity which has a dimensions (L T^-2). So: *The dimension formula of (X) is T and that of (Y) is T^2.The dimension formula of (X) is T and that of (Y) is T^-2The dimension formula of (X) is T^-1 and that of (Y) is T^2.The dimension formula of (X) is T^-1 and that of (Y) is T^-2.
