Answer:

x= 80 cm : Spring stretch

Explanation:

Hooke's law:

The force applied to a spring is proportional to the spring stretching:

F=K*x (Formula (1)

Where:

F=Force applied to the spring (N)

K= spring elasticity constant (N/m)

x= spring stretch (m)

Known data

F=520 N

k=650 N/m

Problem development

We apply formula (1) for calculate the spring strech (x):

F=K*x

520N=(650 N/m) *x

x= (520N) / (650 N/m)

x= 0.8 m = 0.8m* 100cm/m = 80cm

x= 80 cm

What is the number of wavelengths that pass a given point each second called?
denpristay [2]
Since waves are moving, we define frequency as the number of waves that pass a given point in a specified unit of time. The unit commonly used is Hertz which is the number of wave cycles that pass a point in one second.

What effect does a tripling of the net force have upon the acceleration of the object?
dsp73
The formula of net Force is:F = mawhere m is the mass of the objecta is the acceleration of the object
thus, if we triple the net force applied to the object:
3F = maa = 3F / m
The acceleration is also tripled since the force is directly proportional to the acceleration.
