No, the Security Market Line (SML) is not constant over time. It represents the relationship between an investment's expected return and its systematic risk, which can fluctuate due to changes in market conditions, risk preferences, and other factors. As market conditions change, the SML may shift up or down along with expected returns.
The graph would be a straight line with a positive slope, indicating a constant displacement over time.
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.

Motionless objects and objects moving in a straight line with constant speed both have a constant velocity of zero or a constant velocity in a single direction, respectively. They share the characteristic of having a consistent position relative to a reference point over time.
"Constant" means that the speed doesn't change over time.

For motion at constant speed along a straight line, the acceleration is zero.

Time is plotted on the X-axis. Speed or velocity is plotted on the Y-axis. A straight horizontal line on a speed-time graph means that speed is constant. It is not changing over time. A straight line does not mean that the object is not moving!
To identify the constant of proportionality in a graph, look for a linear relationship between the two variables, typically represented as a straight line passing through the origin (0,0). The constant of proportionality is the slope of this line, calculated by choosing two points on the line, finding the difference in their y-values, and dividing it by the difference in their x-values (rise over run). This value represents the ratio of the two variables and remains constant throughout the graph.
Increased worker satisfaction and job security were not direct results of the use of the assembly line. Instead, the assembly line typically led to repetitive work, reduced job flexibility, and increased management control over workers.
Uniform motion is when an object moves with a constant speed in a straight line. Uniform acceleration is when an object's velocity changes at a constant rate. In uniform acceleration, the speed of the object increases or decreases by the same amount over equal time intervals.
