How does SpaceX reduce costs? But introducing reusability cuts all launch costs by the same amount it cuts government launch costs. If this is true, then “flight-proven” rockets could reduce the cost of an ordinary launch to as little as $36 million. That’s even cheaper than the 30% cost reduction that SpaceX initially promised four […]

Why is Mars so radioactive?
Why is Mars so radioactive? Causes: Mars has no protective magnetosphere, as Earth does. As a result, over the course of the next 500 million years, Mars atmosphere was slowly stripped away by solar wind. Between the loss of its magnetic field and its atmosphere, the surface of Mars is exposed to much higher levels […]
How do you calculate the standard hydrogen electrode?
How do you calculate the standard hydrogen electrode? Standard hydrogen electrode aH+ is the activity of the hydrogen ions, aH+ = fH+CH+ / C. pH2 is the partial pressure of the hydrogen gas, in pascals, Pa. R is the universal gas constant. T is the temperature, in kelvins. F is the Faraday constant (the charge […]

What are the 2 types of potential energy?
What are the 2 types of potential energy? There are two main types of potential energy: Gravitational potential energy. Elastic potential energy. What type of mechanical energy is stored in an aerosol can? This means that a particle can have kinetic energy (because it is moving) and elastic potential energy – stored in the springy […]
What is the relationship between vibration and sound?
What is the relationship between vibration and sound? Sound is all about vibrations. The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates. Can sound […]
