If a tuning fork has 75 hz, how many cycles per second does it vibrate?

N = 75 cycles per second

Explanation:

As we know that frequency is defined as the number of cycles per second

so here we can say that frequency is same as the number of cycles per second

so here given that

so here we have

Number of cycles per second = 75 Hz

which three statements are true about all alloys?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
