Four seismometers stations are the minimum needed to calculate the epicenter of an earthquake.

Physics
1 answer:
Gelneren [198K]3 years ago
4 0

<u>Answer:</u>

False, Four seismometer statitons are no required to find the earthquake's epicenter.

<u>Explanation:</u>

The least number of seismometer stations sufficient for finding the epicenter of earthquake is three. Epicenter is point on earth's crust from where the seismic rupture gets originated. Using the distances to the epicenter from atleast three seismometers the epicenter of earthquake can be determined. This distance is used as the radius and 3 circles are drawn. The point at which the 3 circles intersect is called as epicenter of the earthquake. With one seismometer station, we can determine only the distance to the epicenter. With two seismometer station, measurements are ambiguous. Using more than three seismometer stations produces redundant information. Hence three seismometer is sufficient to determine the epicenter of earthquake.

which of the numbers on this figure indicates typical continental conditions (regional metamorphism)?
Tpy6a [65]

The number that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.

<h3>What is regional metamorphism?</h3>

Regional metamorphism occurs when rocks undergoes changes as a result of high temperatures and pressure deep within the earth's crust.

Regional metamorphic rocks are usually foliated or squashed in appearance.

Examples of regional metamorphism rocks are schist and gneiss rocks.

Therefore, the figure that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.

A piece of warm concrete is placed in a cold-water tank, and energy flows between the concrete and the water. Which way does the
sammy [17]

Answer:

Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body warming up. This is a natural phenomenon we experience all the time.

Answer:

1, When Jane brakes, the brakes slow the car wheels turning and the road surface exerts a backwards force on the tires, causing the car to decelerate. The pocket book tends to continue on in a straight line (Newton's first law). If she brakes hard enough that the friction between the book and the car seat is insufficient to decelerate the book as fast as the car is decelerating, the book will slide off the seat, and gravity pulls it to the floor

If a 3.5 gram ping pong ball were traveling to the right horizontally at 12 m/s, and a larger 12 g super ball were thrown direct
algol [13]

Answer:

v = 14.32 m/s

Explanation:

According to the principle of conservation of linear momentum, both the momentum and kinetic energy of the system are conserved. Since the two balls are in the same direction of motion before collision, then;

m_{1} u_{1} + m_{2} u_{2} = (m_{1} + m_{2}) v

0.035 × 12 + 0.120 × 15 = (0.035 + 0.120) v

0.420 + 1.800 = (0.155) v

2.22 = 0.155 v

⇒ v = \frac{2.22}{0.155}

      = 14.323

The velocity of the balls after collision is 14.32 m/s.
