Scientists use a method called triangulation to determine where the earthquake was. It is called triangulation because a triangle has three sides, and it takes three seismographs to locate an earthquake.

<h2>Answer:</h2>

<u>They can find the starting point of earthquake </u><u>by seismometer</u>

<h2>Explanation:</h2>

The epicenter of earthquake can be found by calculating the distance of seismometer and the  time taken by it to reach the siensmometer. The meter is placed on a rock or somewhere where the surface is not shaky and a firm reading could be taken. They should be placed away from noise sources like traffic noise or any other noise. There are two types of waves that are taken into consideration. These waves are called P waves and S waves which are responsible for determining the location of the earthquake.

Charged beads are placed at the corners of a square in the various configurations shown in
Akimi4 [234]

Answer:

The consecutive charge configuration has a more intense field than alternating

Explanation:

In each corner we place a different account there are only two different settings, see attached.

In the case of alternating charging (+ - + -) see diagram 1, the electric field in the center is canceled in pairs, resulting in a zero field

In the case of consecutive loads (+ + - -) in this case we have a result between the two charges, therefore the total field is

          E = 2 k q / ra2 a cos 45

The consecutive charge configuration has a more intense field than alternating

The terminal velocity of a person falling in air depends upon the weight and the area of the person facing the fluid. Find the t
AVprozaik [17]

Answer:

v=115 m/s

or

v=414 km/h

Explanation:

Given data

A_{area}=0.140m^{2}\\  p_{air}=1.21 kg/m^{3}\\  m_{mass}=80kg

To find

Terminal velocity (in meters per second and kilometers per hour)

Solution

At terminal speed the weight equal the drag force

mg=1/2*C*p_{air}*v^{2}*A_{area}\\   v=\sqrt{\frac{2*m*g}{C**p_{air}*A_{area}} }\\ Where C=0.7\\v=\sqrt{\frac{2*9.8*80}{1.21*0.14*0.7} }\\ v=115m/s

For speed in km/h(kilometers per hour)

To convert m/s to km/h you need to multiply the speed value by 3.6

v=(115*3.6)km/h\\v=414km/h
