Draw the location of the epicenter of an earthquake in Carmona, Silang,GMA Cavite if the hypothetical distance of epicenter in C
stellarik [79]

The kinematics and geometry can locate the point where the earthquake occurs: Point of interception of the three circles

The earthquakes occur due to a sudden movement of two tectonic plates, this movement produces longitudinal and transverse waves with different speeds, called S and P waves. The speed of the waves is constant, so we can use the uniform kinematic movement relationship

           v = d / t

Where v is the speed of the wave, d is the distance and t is the time.

The speed of the two types of waves is known, they depend on the material and type of wave varies between 4 and 7 km / S, the time is measured in the seismometers, for which we can calculate the distance.

For a seismometer, the calculated distance corresponds to a circle, so to locate the epicenter of the earthquake we must have a minimum of three earthquakes, the point of intersection of the circles is the place of occurrence of the event, see the attachment for a diagram of the process.

In conclusion, with kinematics and geometry we can locate where the earthquake occurs: Point of interception of the three circles

Help me. ASAP!!!!! 23 POINTS!!!!!!!
Alona [7]
a) Group 2 elements have 2 electrons on their outer shell, so they form a 2+ charge.

b) they lose 2 electrons as they are transferred to the non metal.

c)They obtain this charge as when they are made into an ionic compound the 2 electrons on the outer shell are transferred to the non metal, meaning there are 2 more protons that electrons, giving it a positive charge.

hope this helps! :)

Answer:

\boxed{\sf \lambda \:  = 1.282 \times    {10}^{ 3} nm}

Explanation:

Suppose an electron makes transition from n initial (ni) to n final (nf) then formula for wavelength is given by,

\frac{1}{ \lambda}  = R_H {Z}^{2}  \big(\frac{1}{{n_f^2}}  - \frac{1}{{n_i^2}} \big)

Where,

  • λ is wavelength of photon
  • Rʜ is rydberg constant, the value of Rʜ is

109690 Cm-¹ in <em>Puri Sharma Pathania</em> standard book of physical chemistry &

109737 Cm-¹ according to <em>Wikipedia</em>

  • Z is the atomic number of atom, for hydrogen Z =1,

& according to given data, ni = 5, nf = 3

Solution:

Let's solve for wavelength,

Substituting all the given data in above formula,

\frac{1}{ \lambda}  = 109690 \times  {1}^{2}  \big(\frac{1}{{3^2}}  - \frac{1}{{5^2}} \big)

\frac{1}{ \lambda}  = 109690 \times  {1}^{2}  \big(\frac{1}{{9}}  - \frac{1}{{25}} \big)

\frac{1}{ \lambda}  = 109690 \times  {1}^{2}  \times   \frac{25 - 9}{25 \times 9}

\frac{1}{ \lambda}  = 109690 \times  {1}^{2}  \times   \frac{16}{225}

\frac{1}{ \lambda}  =   7800.18 \: \: cm ^{ - 1}

\lambda = 1.282 \times  {10}^{ - 4} cm

Now we know that, 1 cm = 10000000 nm,

Converting the wavelength from Cm → Nm

\lambda \:  = 1.282 \times  {10}^{ - 4} \times  {10}^{7}

\lambda \:  = 1.282 \times  {10}^{ - 4 + 7}

\sf \lambda \:  = 1.282 \times    {10}^{ 3} nm
