Question
Earthquakes are essentially sound waves—called seismic waves—traveling through the earth. Because the earth is solid, it can support both longitudinal and transverse seismic waves. The speed of longitudinal waves, called P waves, is 8000 m/s Transverse waves, called S waves, travel at a slower 4500 m/s. A seismograph records the two waves from a distant earthquake. The S wave arrives 2.0 min after the PP wave.How far away is the Earthquake. Assume that the waves travel in straight lines, although actual seismic waves follow more complex routes.
Answer:
The distance is
Explanation:
From the question we are told that
The speed of longitudinal seismic wave is
The speed of Transverse seismic wave is
The time difference between the arrival of longitudinal seismic with respect to Transverse waves is
Generally the time difference between the arrival of longitudinal seismic with respect to Transverse waves is mathematically represented as
=>
=>
=>
=>
Septum is the tissue that separates the left and right sides of the heart.
False. The closest galaxy known to us is the Canis Major Dwarf Galaxy which is 236,000,000,000,000,000 km (25,000 light years) from the Sun.

<u>Question:</u>
Two particles are separated by a distance d. At this distance, the strong interaction between them is much greater than the electrical interaction. What are the possible values of d?
a. extremely large values, such as the distances between the planets and sun
b. extremely small values, such as the distances between particles in an atomic nucleus
c. values between 1 mm and 1 m
d. values between 1 m and 1 km
<u>Answer:
</u>
The possible values of d are extremely small values, such as the distances between particles in an atomic nucleus.
<u>Explanation:
</u>
Any kind of interaction requires force between the interacting materials and that force tends to directly proportional to the product of mass of the materials and inversely proportionate to distance of separation of the interacting materials.
So, mostly based on the distance of separations, an interaction can be termed as strong or weak interactions. If the interacting particles are placed at higher distance, then the force acting between them tend to decrease leading to weak interaction.
An interaction stronger than electrical interactions can occur within subatomic particles. This leads to binding of the subatomic particles as an atom. So the distance d should be extremely small in subatomic particles like distance between the particles in an atomic nucleus.
