Answer:
Maximum speed ( v ) = 10.4 m/s (Approx)
Explanation:
Given:
Amplitude A = 15.0 cm = 0.15 m
Frequency f = 11.0 cycles/s (Hz)
Find:
Maximum speed ( v )
Computation:
Angular frequency = 2πf
Angular frequency = 2π(11)
Angular frequency = 69.14
Maximum speed ( v ) = WA
Maximum speed ( v ) = 69.14 x 0.15
Maximum speed ( v ) = 10.371
Maximum speed ( v ) = 10.4 m/s (Approx)
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.

Explanation:
Boiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). If the bubbles were caused by the decomposition of a molecule into a gas (such as H2O →H2 and O2), then boiling would be a chemical change.
Answer:
Change in momentum,
Explanation:
It is given that,
Mass of the basketball, m = 601 g = 0.601 kg
The basketball makes an angle of 29 degrees to the vertical, it hits the floor with a speed, v = 6 m/s
It bounces up with the same speed, again moving to the right at an angle of 29 degree to the vertical. We need to find the change in momentum. It is given by :
So, the change in momentum of the basketball is 6.3 kg-m/s. Hence, this is the required solution.
