The y-intercept of a position-time graph of an object gives the average velocity of the object.

<em>The y-intercept of a position-time graph of an object gives the average velocity of the object is False.</em>

<u>Answer:</u> <em>False. </em>

<u>Explanation:</u>

The initial position of the object can be obtained by calculating the Y intercept of  a position-time graph.  In a position-time graph, the independent  variable is time  and dependent variable is position. Y axis is the position axis and x axis is the time axis.

The equation of the graph is given by y =mx + c. m is the slope of the graph and c is the y intercept. When a particle starts from the origin its y intercept is zero.

The nature of the graph gives us an idea about velocity. When the velocity is positive, the position- time graph has positive slope and when the velocity is positive the graph has negative slope.

andriy [413]

The bottleneck event of the plants in an area results in secondary succession.

<h2>What is bottleneck event?</h2>

A bottleneck is an event that drastically reduces the population size of an organism. The bottleneck may be caused by various events, such as an environmental disaster, the hunting or habitat destruction that results in the deaths of organisms.

<h3>Secondary succession</h3>

Secondary succession is a type of ecological succession in which plants and animals recolonize a habitat after a major disturbance such as a devastating flood, wildfire, landslide, lava flow, or human activity e.g., farming or road or building construction.

serious [3.7K]

The distance between two consecutive nodes and the amplitude after 0.56s are m/2 and 1.75×10^(-4) m respectively.

<h3>What's the distance between consecutive nodes of the displacement of air molecules?</h3>
  • Wavelength is the distance between two consecutive nodes or toughs or crests or anti-nodes.
  • So, distance between consecutive nodes = wavelength = 2π÷k

= 2π/(4π÷m)

= m/2

<h3>What's the amplitude after 0.56s of the displacement of air molecules?</h3>

Displacement after 0.56 s = 0.008×cos(50π×0.56s)

=1.75×10^(-4) m

Thus, we can conclude that the distance between consecutive nodes and displacement after 0.56 s are m/2 and 1.75×10^(-4) m respectively.
