Answer:
See the explanation below.
Explanation:
A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.
The invasive species increases its density in the occupied area or colonizes new territories over time.
That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.
Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.
So, the weight is supported by the tension in the two wires, but only part of the tension goes in holding the body: the vertical component.
If the angle between the ceiling and the wire is 40 deg, then the vertical component is
T_y = T * sin(40),
There are two wires, so together they do
2*T*sin(40)
And all this holds the weight of the body, so:
2*T*sin(40)=150 ----> T = 75/sin(40)~116.68 N,
Notice how it is larger than 150N (both wires is ~ 233 N), as the angle becomes smaller, there is less tension that is vertical, so one needs more tension to make the vertical component as large as (half) the weight of the body
Hope it helps!
To what? You did not put the question.
Explanation :
We know that the slope of velocity -time graph gives the acceleration. Acceleration of an object is defined as the rate of change of velocity i.e.
Suppose a driver suddenly applies brakes. In this case the initial velocity of his or her vehicle is more and the final velocity is less.
So, the acceleration is negative in this case i.e. the object is decelerating.
A negative slope on the velocity versus time graph indicates that an object is not accelerating. This statement is false as the object is decelerating.
