What else can I help you with?
A scientist wants to display how the number of frogs in a pond gradually declined over a 10-year period. What sort of visual display should the scientist use?
a line graph
Is every tree a bipartite graph?
Yes, every tree ia a bipartite graph (just see wikipedia).
What is a hamiltonian path in a graph?
A Hamiltonian path in a graph is a path that visits every vertex exactly once. It does not need to visit every edge, only every vertex. If a Hamiltonian path exists in a graph, the graph is called a Hamiltonian graph.
What does controlled item for a graph mean?
A controlled item for a graph is a variable that the experimenter manipulates or controls in order to observe its effect on another variable. This allows researchers to test hypotheses about the relationship between variables and determine causality within the graph. By controlling certain variables, researchers can isolate the effects of specific factors on the outcomes of the graph.
What is the nature of graph between kinetic energy and mass when velocity is constant?
When velocity is constant, kinetic energy is directly proportional to mass. This means that as mass increases, kinetic energy also increases proportionally. The graph would be a straight line with a positive slope.
Area under the velocity time graph line is 40 M. What physical quantity does this area represent?
It represent the distance covered is 40 metre.
What is the unit of a physical quantity which is represented by area under a velocity time graph?
the physical quantity is distance and unit is meters
What is the physical quantity measured under a speed time graph?
The physical quantity measured under a speed-time graph is acceleration. This is because acceleration is represented by the gradient of the graph, where a steeper gradient indicates a higher acceleration.
What physical property does the slope of a velocity time graph represent?
velocity.
What does linegraph mean?
A line graph is often used to represent a set of data values in which a quantity varies with time
What are the importance of zeros on a graph in physical science?
Zeros on a graph in physical science represent points where a quantity being measured is equal to zero. They can indicate important values such as equilibrium points, boundaries, or critical thresholds. Zeros can help to identify key features of a system and provide insights into its behavior and properties.
Which physical quantity is given by slope of v-t graph?
The physical quantity given by the slope of a velocity-time graph is acceleration. This is because the slope represents the rate of change of velocity over time, which is how acceleration is defined (acceleration = change in velocity / time taken).
Can a bar on a bar graph show the quantity of a certain product sold for a particular month of the year?
Sure, on a bar graph, each bar represents a quantity of something. If the entire graph is for a certain product, then each bar could represent the quantity sold each month. Or the entire graph could be for a particular month, with each bar representing sales during that month, for different products.
What physical quantity does the slope represent of a velocity time graph?
The slope of a velocity-time graph represents acceleration. A positive slope indicates an increase in velocity over time, while a negative slope indicates a decrease in velocity (deceleration). The steeper the slope, the greater the acceleration or deceleration experienced by the object.
What is a concrete vs a pictorial graph?
A concrete graph uses physical objects to represent data, such as bar graphs made with blocks. A pictorial graph uses pictures or symbols to represent data, like a graph showing ice cream sales using ice cream cones.
Which graph is used to measure quantity?
bar graph
What is the standard of measure for a physical quantity and is included as part of the x and y axes labels on a line graph?
Unit of Measure
