Along string is moved up and down with simple harmon motion with a frequency of 42 hz. the string is 543 m long and has a total mass of 47.2 kg. the string is fixed at both ends. what is the tension in the string?

T = 6051.70 N

Explanation:

Given;

Frequency, f = 42 Hz

Length of the string, L = 543 m

Mass of the string, m = 47.2 kg

Now,

the frequency is given as:

where, T is the tension in the string

M is the mass per unit length = m/L = 47.2/543 = 0.0869

on substituting the values in the above equation, we get

or

or

T = 6051.70 N

the closer the planet is to the sun, the larger the gravity

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
