To calculate for the force in a spring, we use Hooke's Law which relates force and the displacement of the spring. It is said that the force is directly proportional to the displacement. So, it will have the equation F = kx where k is a constant and it is the spring constant.

F = kx
F = 45 N/m (0.03)
F = 1.35 N

g determine what frequency is required of a source powering a 100 uf capacitor a 500 ohm resistor and a s50 mH inductor in serie
polet [3.4K]

Answer: 71.16\ Hz

Explanation:

Given

Capacitance C=100\ \mu F

Resistance R=500\ \Omega

Inductance L=50\ mH

In LCR circuit, current is maximum at resonance frequency i.e.

X_L=X_C\ \text{and}\ \omega_o=\dfrac{1}{\sqrt{LC}}

Insert the values

\Rightarrow \omega_o=\dfrac{1}{\sqrt{50\times 10^{-3}\times 100\times 10^{-6}}}\\\\\Rightarrow \omega_o=\dfrac{1}{\sqrt{5}\times 10^{-3}}\\\\\Rightarrow \omega_o=0.447\times 10^{3}

Also, frequency is given by

\Rightarrow 2\pi f=\omega_o\\\\\Rightarrow f=\frac{\omega_o}{2\pi}

\Rightarrow f=\dfrac{1}{2\pi}\times 0.447\times 10^3\\\\\Rightarrow f=71.16\ Hz

A student rides her bicycle to school, which is 6 km north of her home. After school, she rides to the grocery store that is 2 k
Free_Kalibri [48]
The total distance traveled from home to the grocery store would be 8km.

Because both distances she traveled were in the same direction, north, both displacement and distance travel were equal.

If the student traveled in two different directions, such as north to the school and south to the grocery store, her distance traveled would be 8km but her displacement would only be 6km.

Which option below best explains why the second law of thermodynamics is
Llana [10]

''The freezer and room are not an isolated system, since electrical energy flows in.'' is the correct statement.

<h3>What is Second Law of Thermodynamics?</h3>

The Second Law of Thermodynamics says that "in all energy exchanges, if no energy enters or leaves the system, the potential energy of the state will always be less than the energy of the initial state."

So we can conclude that ''The freezer and room are not an isolated system, since electrical energy flows in.'' is the correct statement.
