Istretch a rubber band and "plunk" it to make it vibrate in its fundamental frequency. i then stretch it to twice its length and make it vibrate in the fundamental frequency once again. the rubber band is made so that doubling its length doubles the tension and reduces the mass per unit length by a factor of 2. the new frequency will be related to the old by a factor of:

The new frequency (F₂ ) will be related to the old frequency by a factor of one (1)

Explanation:

Fundamental frequency = wave velocity/2L

where;

L is the length of the stretched rubber

Wave velocity =

Frequency (F₁) =

To obtain the new frequency with respect to the old frequency, we consider the conditions stated in the question.

Given:

L₂ =2L₁ = 2L

T₂ = 2T₁ = 2T

(M/L)₂ = 0.5(M/L)₁ = 0.5(M/L)

F₂ =

Therefore, the new frequency (F₂ ) will be related to the old frequency by a factor of one (1).

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
