Which one of the following scholars suggests the earth’s origin ...
Otto Schmidt, a Soviet scientist, was one of the scholars who suggested that the Earth's origin could be attributed to gases and dust particles. Schmidt proposed this theory as part of his research on the formation of celestial bodies, including planets like Earth. Therefore, option (d) is the correct choice.

Origin of Earth according to O Schmidt

According to O Schmidt, the earth's origin is from gases and dust particles. This theory is known as the Nebular Hypothesis, which suggests that the solar system, including the Earth, was formed from a nebula - a cloud of gases and dust particles.

Nebular Hypothesis

- The Nebular Hypothesis proposes that the sun and planets were formed from a rotating disk of dust and gases.
- Over time, gravity caused the dust and gases to clump together, eventually forming the Earth and other celestial bodies.

Role of Gases and Dust Particles

- The gases and dust particles in the nebula provided the building blocks for the formation of the Earth.
- Through processes such as accretion and gravitational attraction, these particles gradually came together to form larger bodies like planets.

Supporting Evidence

- The Nebular Hypothesis is supported by observations of other planetary systems and the formation of stars.
- It also explains the composition and structure of the solar system, including the similarities and differences between the planets.

Conclusion

O Schmidt's theory of the Earth's origin from gases and dust particles provides a plausible explanation for the formation of our planet within the context of the larger solar system.

A particle accelerator functions by exerting a magnetic field on charged particles which are shot into the accelerator. The magnetic field causes the charged particles to move around in a circle of radius R that can be predicted by the following equation, where mp is the mass of the particle in kilograms, v is the initial speed at which the particle was shot in meters per second, q is the charge of the particle in Coulombs, and B is the strength of the magnetic field in Tesla.R=mpv/qBA proton weighs approximately 1 amu (atomic mass units) and has a charge of 1.6∗10−19 C. An electron has the same magnitude of charge, but it has about 1/1800of the protons mass. What would happen to radius R if we were to suddenly switch the particle in the accelerator from a proton to an electron, keeping all of the other conditions the same?

A physicist performs a series of experiments to determine the relative magnitude of electric charge on four particles. A given particle is considered to have a higher magnitude of charge than another if it will push out (or draw in) a positive test charge farther than the other particle.A particle that pushes the test charge has positive charge, while a particle that pulls (or draws in) the test charge has negative charge. This is known as the sign of the charge. Magnitude of charge is unrelated to sign.The experiment is conducted on a horizontal axis that measures from 20m in total: from –10m on the left to +10m on the right, with a measurement of 0m in the middle.Experiment 1Particle A is placed at position –5m on the horizontal axis. The test charge has a specific magnitude of charge and is located at +3m on that same axis. The result of the experiment is that the test charge is displaced to +7.5m.Experiment 2Particle B is placed at position –8m on the horizontal axis. The test charge has the same magnitude of charge as the previous experiment and is located at 0m on that same axis. The result of the experiment is that the test charge is displaced to –7.5m.Experiment 3Particle C is placed at position 0m on the horizontal axis. The test charge has the same magnitude of charge as the previous experiment and is located at +8m on that same axis. The result of the experiment is that the test charge is displaced to +10m.Experiment 4Particle D is placed at position –5.5m on the horizontal axis. The test charge has the same magnitude of charge as the previous experiment and is located at +2.5m on that same axis. The result of the experiment is that the test charge is displaced to +7.5m.Q.Which of the following represents the order of charge of the four particles, from highest to lowest?

Sound waves travel through a medium by mechanically disturbing the particles of that medium. As particles in the medium are displaced by the sound wave, they in turn act upon neighboring particles. In this fashion, the wave travels through the medium through a parallel series of disturbed particles. Like in other forms of motion, the rate at which the sound wave travels can be measured by dividing the distance over which the wave travels by the time required for it to do so. Study 1A group of students hypothesizes that the velocity of sound is dependent upon the density of the medium through which it passes. They propose that with more matter in a given space, each particle needs to travel a shorter distance to disturb the adjacent particles. Using two microphones and a high speed recording device, the students measured the delay from the first microphone to the second. They chose a variety of media, shown in Table 1, and measured the velocity of sound through each using their two-microphone setup. The results are found in Table 1.Study 2The students wanted to test their hypothesis by using the same medium at different densities. To do this, they heated pure water to various temperatures and repeated the procedure described in Study 1. Their results can be found in Table 2.According to Study 2, water at which of the following temperatures yields the greatest velocity of sound?
