What are the first three harmonics of a note produced on a 0.31 m long violin string if the waves on this string have a speed of

274.4 M/s
Physics

Answer:

442 Hz, 882 Hz, 1330 Hz

Explanation:

Given data:  length of the string= 0.31 m = 31 cm

speed of the waves = 274.4 M/s or 2740 cm/s

Wavelengths are

62 cm

31 cm and

62 / 3  =  20.67 cm

The frequencies associated with these wavelengths ( which are the 1st, 2nd and 3rd harmonics )

are

27440/ 62 =  442.6 = 442 Hz

27440/31  = 885.2  = 882 Hz

27440 / 20.67  = 1328 = 1330 Hz

A sphere is charged with electrons to
pishuonlain [190]
A sphere is charged with electrons to −9 × 10−6 C. The value given is the total charge of all the electrons present in the sphere. To calculate the number of electrons in the sphere, we divide the the total charge with the charge of one electron.

N = 9 × 10−6 C / 1.6 × 10−19 C
N = 5.6 x 10^13

What do you understand by upthrust Force​
Sedaia [141]

Answer:

hope you like it

Explanation:

An object that is partly, or completely, submerged experiences a greater pressure on its bottom surface than on its top surface. This causes a resultant force upwards. This force is called upthrust . The upthrust force is equal in size to the weight of the fluid displaced by the object.

Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.It is the force that pushes an object up. The upthrust, or buoyancy, keeps ships afloat. The upthrust, or buoyancy, keeps swimmers on top of the water.
