<span>If the data comes from only two seismic stations, pinpointing the epicenter accurately becomes quite difficult. This is because triangulation requires data from three different stations. With just two, the two circles representing possible epicenter locations overlap at two points, so there are two potential epicenters instead of one.</span>

Response:

Seismic waves generated during an earthquake are captured by seismographs, devices that record the arrival times of P and S waves. These instruments aid in pinpointing the earthquake's epicenter. When an earthquake occurs, seismographs placed near the affected area detect seismic activity and each produces a circular area representing possible locations.

When the circles from three distinct seismographs intersect at one point, that location marks the approximate epicenter. This method is efficient and widely used.

However, if data is only obtained from two stations, only two circles can be drawn, which intersect at two distinct points. Consequently, this makes determining the precise epicenter difficult.

serg [3582]
The kangaroo reaches a maximum vertical altitude of 2.8 m, which can be calculated using the formula 2.8 = 1/2 * 9.8 * t^2. Thus, applying the equation s = ut + 1/2at^2.

A champion athlete can produce one horsepower (746 W) for a short period of time. The number of 16-cm-high steps a 70-kg athlete
Sav [3153]

Answer:

407 steps

Explanation:

Based on the question,

P = mgh/t........... Equation 1

Where P stands for power, m is mass, g denotes gravity, h is height, and t represents time.

Rearranging the equation to solve for h, we have:

h = Pt/mg............. Equation 2

Providing values: P = 746 W, t = 1 minute = 60 seconds, m = 70 kg.

Given constant: g = 9.8 m/s²

By substituting into equation 2

h = 746(60)/(70×9.8)

h = 44760/686

h = 65.25 m

h = 6525 cm

Calculating number of steps: 6525/16

The resulting number of steps = 407 steps

A careful photographic survey of Jupiter’s moon Io by the spacecraft Voyager 1 showed active volcanoes spewing liquid sulfur to
Sav [3153]

Answer:

529.15 m/s

Explanation:

h = Highest point = 70000 m

g = Gravitational acceleration = 2 m/s²

m = Sulfur's mass

Since both potential and kinetic energies are conserved

mgh=\dfrac{1}{2}mv^2\\\Rightarrow h=\dfrac{v^2}{2g}\\\Rightarrow v=\sqrt{2gh}\\\Rightarrow v=\sqrt{2\times 2\times 70000}\\\Rightarrow v=529.15\ m/s

The velocity at which the liquid sulfur exited the volcano is 529.15 m/s

A runner runs 4875 ft in 6.85 minutes. what is the runners average speed in miles per hour?
Keith_Richards [3271]

Calculating the average speed is straightforward by using the formula involving distance and time:

average speed = distance / time

 

Thus, we have:

average speed = 4875 ft / 6.85 minutes

<span>average speed = 711.68 ft / min</span>

kicyunya [3294]
No, that statement isn't correct because an atom is made up of two main regions and three subatomic particles: protons, neutrons, and electrons. Each of these particles is smaller than the atom itself, qualifying them as subatomic particles. To be classified as an atom, both protons and electrons are essential — for example, hydrogen has one proton and one electron. Neutrons don't influence the atomic electrical charge; they only add to the atomic mass.
