Answer: Hip

Explanation: The ball and socket joint can be seen in the hip. It is located where femur(thigh bone) meets the pelvic bone.

The ball and socket joint is a type of synovial joint in which one bone looks exactly as a ball and another bone bone looks exactly like socket or cavity in which the first bone will fit.

This helps in the movement of the bone in all the directions. So, as we know the hip moves in every direction it has ball and socket joint.

The D string on a violin has a frequency of 293 Hz when it is in tune. Ca<br> lculate the period
masya89 [10]

The period of the D string on the violin would be 0.0034 seconds.

<h3>What is the period of a wave?</h3>

The period of a generated wave is the time it takes for the wave's wavelength or successive crests or troughs to pass through a specific point. In other words, it is the time required to complete a full cycle of oscillation.

Mathematically, the period of a wave is given by:

Period = 1/f

where f is the frequency of the wave.

In the case of the D string of the violin in the illustrated problem, the frequency of the wave is given as 293 Hz when it is in tune. Thus, the period can be calculated as:

Period  = 1/293

            =  0.0034 seconds

Thus, the period of oscillation of wave generated by the D string on the violin with a frequency of 293 Hz is 0.0034 seconds.

Write a short note on asexual reproduction in<br> bread mould
snow_tiger [21]

During Asexual reproduction, in the interior side  of Sporangium spores are made by mold and spreading of more mold occurs and  Sporangium will be breaking during the time, when the spores are ready for leaving out.

<u>Explanation:</u>

The formation of spores is the asexual reproduction method that occurs in fungi which is a non flowering plant and bacteria. Many number of smaller and tiny spores that are tough, round shaped and microscopic, are produced by parent plants that has the ability to grow into many newer plants in asexual reproduction method only under certain conditions.   Multiple number of spores in the sacs of Rhizopus that is called as sporangia. Te structure of these sporangia is like a knob and these are  are present at the top of  hyphae which is like a thread.

When these sporangia bursts, the spores are scattered by rain, wind or insects and under suitable conditions develop into a new Rhizopus plant, when they fall on a suitable substance like bread. When a break occurs in these sporangia, scattering of these spores occurs and these develop into a new plant under some suitable conditions, when these falls on a substance say for an instance bread.
