An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. The average speed of the
Norma-Jean [14]

Answer:

1083.173 km

Explanation:

Speed of longitudinal waves = 9.1 km/s

Speed of transverse waves = 5.7 km/s

Time taken by the longitudinal wave is t

Time taken by the transverse wave is t+71

Distance = Speed × Time

Distance traveled by the longitudinal wave

\text{Distance}=9.1t

Distance traveled by the transverse wave

\text{Distance}=5.7(t+71)

Since both distances are equal

9.1t=5.7(t+71)\\\Rightarrow 9.1t-5.7t=404.7\\\Rightarrow 3.4t=404.7\\\Rightarrow t=\frac{404.7}{3.4}=119.03\ s

The time taken by the longitudinal wave is 119.03 seconds

Distance traveled by the longitudinal wave

9.1t=9.1\times 119.03=1083.173\ km

The earthquake is 1083.173 km away

Why do two resistors in parallel together contain less resistance than the same two resistors in series?
stira [4]

Answer : When resistors are connected in parallel, the supply of current is equal to the sum of the currents passing through each of the resistors.

To be specific, the currents in the branches of a parallel circuit add up to the supply current. When resistors are connected in parallel, they have the same potential difference across them.

When resistors are connected in series the total resistance is greater than the individual resistances, hence the currents flow is less.

When resistors are connected in parallel, more current flows from the source than would flow for any of them individual resistors, so the total resistance is lower.

During summer in the northern hemisphere _____.
Kipish [7]
For part of our orbit the northern half of Earth is tilted toward the Sun. This is summer in the northern hemisphere; there are longer periods of daylight, the Sun is higher in the sky, and the Sun's rays strike the surface more directly, giving us warmer temperatures
