In the science fiction story "The little prince is an android" a second journey of the character from the novel by Antoine de Saint-Exupéry is proposed, in which he visits a planet where respect for the ecosystem is paramount. They have developed a technology capable of storing the energy released in electrical storms where 92 lightning strikes are produced every second. In a simplified way, lightning occurs when the potential difference between the cloud and the planet's surface reaches at least 2.6 cross times 10 to the power of 7 volts. The electrical currents generated in lightning are about 3.4 cross times 10 to the power of 4 amperes on average. Determine the average power of 92 lightning strikes produced with these values of potential difference and an electric current. Select one: O 8.8x 10¹1 W 9.6 × 10⁹ W 8.1 x 10¹3 W 7x 10¹ W

Two electrons are initially separated by 5.0 X 10^-8 m. When they are both released, they fly apart. How fast would they be flying apart when they are separated by a large distance?
What is the velocity of an electron that has a momentum of 3.041021kgm/s ? Note that you must calculate the velocity to at least four digits to see the difference from c.
Problem A newly discovered light positively charged particle has a mass of m and charge q. Suppose it moves within the vicinity of an extremely heavy (fixed in place) particle with a positive charge Q and mass M. When the light particle is xi distance from the heavy particle, it is moving directly away from the heavy particle with a speed of vi. a) What is the lighter particle's speed when it is xf away from the heavy particle? (Consider the Newtonian Gravitation acting between the two charged particles. Ignore the effects of external forces) Solution: We may solve this using two approaches. One involves the Newton's Laws and the other involving Work-Energy theorem. To avoid the complexity of vector solution, we will instead employ the Work-Energy theorem, more specifically, the Conservation of Energy Principle. Let us first name the lighter particle as object 1 and the heavy particle as object 2. Through work-energy theorem, we will take into account all of the energy of the…

2)One hazard of space travel is debris left by previous missions. There are several thousand objects orbiting Earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint. Calculate the force exerted in newtons by a 0.190 mg chip of paint that strikes a spacecraft window at a relative speed of 4.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10−8 s.
