How high up on a building will a 15 foot ladder? Answer Expert Verified Use the Pythagorean theorem: The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building. What length of ladder is needed to reach a height of 7ft along the wall when the base of the ladder is 4 […]
What are the three functions of the Golgi apparatus?
What are the three functions of the Golgi apparatus? The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations. As the secretory proteins move through the Golgi apparatus, a number of chemical modifications may transpire. What would happen to the life of cell if there […]
What are the four properties of an ionic compound?
What are the four properties of an ionic compound? Properties Shared by Ionic Compounds They form crystals. They have high melting points and high boiling points. They have higher enthalpies of fusion and vaporization than molecular compounds. They’re hard and brittle. They conduct electricity when they are dissolved in water. They’re good insulators. Which of […]
How much time is a parsec?
How much time is a parsec? It is defined as 360×60×60/2π astronomical units (AU), which is equivalent to about 19.17 trillion miles, or about 3.262 light-years. The Star Wars parsec appears to be equivalent to the real-world measurement: The Essential Atlas says a parsec is 3.26 light-years. How many parsecs are in the universe? The […]
What would happen if temperature and precipitation changed in a climate zone?
What would happen if temperature and precipitation changed in a climate zone? Changes in temperature and precipitation can disrupt a wide range of natural processes, particularly if these changes occur more quickly than plant and animal species can adapt. In response, average temperatures at the Earth’s surface are rising and are expected to continue rising. […]
What is the relationship between temperature and kinetic energy answers?
What is the relationship between temperature and kinetic energy answers? Kinetic energy is directly proportional to the temperature applied. Basically with increase in temperature the vibration / collision of molecules increase hence kinetic energy increases. What is the relationship between the kinetic energy of molecules in an object? Explanation: The kinetic energy of the molecules […]
How can matter be transferred?
How can matter be transferred? In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter. How energy […]
Does photoelectric current depend on frequency?
Does photoelectric current depend on frequency? Photoelectric effect can be explained as: it takes a specific energy to launch an electron from a metal surface. This energy is the work function which relies upon the metal. Electrons can pick up energy by collaborating with photons. Current is not dependent on the frequency of photons. What […]
Is gravity the same in a plane?
Is gravity the same in a plane? You are correct that the force of gravity is slightly less the further you get from the earth. Airlines typically cruise around 30,000 – 35,000 feet. The force of gravity on Everest is about 0.434% less than the standard 9.8N/kg. This means that one pound at Sea Level […]
