24 kg
Step-by-step explanation:
You start by calculating the linear mass density of the rod:
d = m/L = (40 kg)/(5 m) = 8 kg/m
So for a 3-m long bar, the mass can be calculated as follows:
m = d×L = (8 kg/m)(3 m) = 24 kg
Answer:
Option B and C are correct.

are the expression incorrect for slope
Step-by-step explanation:
Slope is defined as the change in the dependent variable relative to the change in the dependent variable
or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.
The vertical changes between any two points is rise
The horizontal changes between any two points is run.
Formula for slope is given by:
For any two points
and 
then slope is:
or we can write this as:
Δy = 
Δx = 
⇒
Therefore, the expression which are incorrect for slope are;
