Can u breathe on Mercury? Rough Surface – Mercury is a rocky planet, also known as a terrestrial planet. Mercury has a solid, cratered surface, much like the Earth’s moon. Can’t Breathe It – Mercury’s thin atmosphere, or exosphere, is composed mostly of oxygen (O2), sodium (Na), hydrogen (H2), helium (He), and potassium (K). Can […]
Which part of a cloud is more likely to be positively charged?
Which part of a cloud is more likely to be positively charged? The larger and denser graupel is either suspended in the middle of the thunderstorm cloud or falls toward the lower part of the storm. The result is that the upper part of the thunderstorm cloud becomes positively charged while the middle to lower […]
What is the difference between the driving frequency and the natural frequency of an oscillator?
What is the difference between the driving frequency and the natural frequency of an oscillator? When the oscillating system starts oscillating on its own at a frequency , then this frequency is called natural frequency. But a system oscillating due to external excitation with a frequency , then this frequency is called driving frequency. What […]

Why is there more oxygen in the atmosphere now?
Why is there more oxygen in the atmosphere now? Oxygen levels are generally thought to have increased dramatically about 2.3 billion years ago. Photosynthesis by ancient bacteria may have produced oxygen before this time. In addition, early plants and algae began to release oxygen at a faster rate. … What would happen if there was […]
Is Nuclear Physics a good career?
Is Nuclear Physics a good career? For academic research jobs, nuclear physics may well be a better choice, while the opportunity to design real-world solutions to power generation and medical problems is a major benefit of studying nuclear engineering. Is nuclear physics harmful to humans? Nuclear radiation can ionise chemicals within a body, which changes […]
What attributes did all the stable orbits have in common?
What attributes did all the stable orbits have in common? A stable orbit is an orbit that repeats indefinitely, without ever changing shape.
