solution:
the spring force exerted by spring with spring constant k is given by
where k is spring constant
and x is deformation of spring
in order to calculate word done by the spring
the work done by the spring as it is compressed from x=0 to x=L
inserting the limits x=0 and x=L
we get work done in terms of k and L
By knowing the distance between two objects we can not get enough ideas about the location of these respective objects. It can be easily understood from a simple example.
Let us consider two bodies A and B which are in a two dimensional plane. .Let the co-ordinates of body A is [2,2].
Let us consider two possible co-ordinate pairs [1,0] and [0,1]
Let the body B is at [1,0].
Hence the distance between A and B is
Let the body B is shifted to [0,1] now.
Now the distance between A and B will be
Here we observe that distance in each case is same .But in first case the body B was on +X- axis while in second case the body B was on +Y- axis.
Hence distance between points may be same in different planes, but only the distance can not get enough ideas about the location of the objects.It is the points in specific reference frames gives the ideas about the location of the objects. As position is relative ,hence for complete location of a object,the observer also plays a vital role here.
Answer:
Explanation:
The main reason spiders spin webs is to catch their dinner. When an insect, such as a fly, flies into a spider's web, it gets stuck on the sticky threads. When a spider catches prey in the sticky strands of its web, it approaches the trapped insect and uses its fangs to inject venom.

Answer:
Power is defined as Work / Time
P1 = P2 = W1 / T1 = W2 / T2 W1 and W2 are not necessarily the same Power expended depends on both work input over a unit of time
