Since you are looking for the speed, you need to rearrange the formula which is f = speed / wavelength. That should give you speed = f (wavelength.) All you need to do next is to substitute the value to the following equation. speed = 250 Hz (6.0m) that should leave you with 1500 m/s which is very fast.
compound is covalent! The bond between HI is a polar covalent bond. ... It is because Hydrogen is electropositive in nature in comparison to Iodine.
Answer:
C) Momentum
Explanation:
Refers to an objects mass in motion.
The answer is C. nebular are star nurseries. When the massive gas being collapsing in its own weight. Local areas of gas begin to coalesce under gravity. Due to enormous pressure, nuclear fusion begins and a protostar is formed. The protostar grows into the sun as more hydrogen fuses at the core. The planetesimal materials at the edges of the protostellar discs coalesce to form planets that orbit the star.
Answer:b) atoms
Explanation:which are in turn made up of protons, neutrons and electrons
