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.

How does the graph of displacement vs. time look for something moving at a constant positive velocity?
The graph would be a straight line with a positive slope, indicating a constant displacement over time.
What describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.
If a car is traveling in a straight line at a constant speed is it accelerating?
No, if a car is traveling in a straight line at a constant speed, it is not accelerating. Acceleration refers to a change in speed or direction, which is not occurring in this scenario.
For an object that is speeding up at constant rate how would the acceleration vs time graph look?
A line angled upward
What do motionless objects have in common with objects that are moving in a straight line with speed?
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.
What happens to the spped if a car is going on a straight line at constant speed?
"Constant" means that the speed doesn't change over time.
What is a vertical line with a rise over run relationship that does not exist?
It is a line of the form y = c where c is any constant.It is a line of the form y = c where c is any constant.It is a line of the form y = c where c is any constant.It is a line of the form y = c where c is any constant.

For motion along a straight line a horizontal line on a speed over time graph indicates graph indicates that what is zero?
For motion at constant speed along a straight line, the acceleration is zero.

A line angled upward

What does it mean if a line is flat on a distance-time graph?
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!
Which of the following was not a result of the use of the assembly line?
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.
What is the Difference between Uniform motion and uniform acceleration?
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.
What characterizes constant velocity motion on a velocity-time graph?
On a velocity-time graph, constant velocity motion is characterized by a horizontal line where the velocity remains the same over time. The slope of the line is zero, indicating that the acceleration is zero and the object is moving at a steady speed.
