Where do we find the fastest moving galaxies? In the center of our Milky Way galaxy, scientists have spotted the fastest star ever detected, moving at more than 8% of the speed of light. Our galaxy’s center features the supermassive black hole Sagittarius A* (Sgr A*), which is as massive as about 4 million suns. […]
What are the 5 components of health-related physical fitness?
What are the 5 components of health-related physical fitness? 5 Components of Physical Fitness Cardiovascular Endurance. Muscular Strength. Muscular endurance. Flexibility. Body Composition. What are the 5 components of health related fitness and give their definition? There are five components of physical fitness: (1) body composition, (2) flexibility, (3) muscular strength, (4) muscular endurance, and […]
What does static pressure mean?
What is the relation between momentum and kinetic energy?
What is the relation between momentum and kinetic energy? There is a relation between kinetic energy and momentum as both the properties are linked with velocity. Momentum gets expressed as a multiplication of velocity and mass, whereas kinetic energy is the product of the square of speed and half of the mass. What happens to […]
How do you write a qualitative and quantitative observation?
How do you write a qualitative and quantitative observation? Qualitative observations use your senses to observe the results. (Sight, smell, touch, taste and hear.) Quantitative observations are made with instruments such as rulers, balances, graduated cylinders, beakers, and thermometers. These results are measurable. What are the advantages of giving qualitative observation? 1 Captures the Essence […]
What would happen to the human body if one of the body systems stopped working?
What would happen to the human body if one of the body systems stopped working? After one system shuts down, the others would slowly start to shut down as well until the body can no longer maintain homeostasis and the person would slowly die. 3. All systems would be working together but the main ones […]
Does speed of sound depend on humidity?
Does speed of sound depend on humidity? The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. Dry air absorbs far more acoustical energy than does moist air. This is because moist air is less dense than dry […]
How do you find the refractive index of water?
How do you find the refractive index of water? The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in […]
Can you open a digital gun safe with a magnet?
Can you open a digital gun safe with a magnet? Locksmith demonstrated recently at a business meeting in Vancouver, Canada. He showed that, using a rare earth magnet, one can exploit the nickel piece in this Sentry Electronic Safe to get it open without any damage. Are Cannon safes easy to break into? Whether you […]
What is the difference between reflection and reflective practice?
What is the difference between reflection and reflective practice? Reflective practice is ‘learning through and from experience towards gaining new insights of self and practice’ (Finlay, 2008). Reflection is a systematic reviewing process for all teachers which allows you to make links from one experience to the next, making sure your students make maximum progress. […]
