Answer:
GPS Satellites.
Explanation:
You will always be able to have access to 4 of them no matter where you are on the Earth. This is useful for triangulation.
The answer here would be infrared waves. Hot objects and humans give off heat in the form of infrared light, thermal imaging technology in the goggles enable them to catch this light emitted by these objects
If the atom is neutral, then the number of electrons will ALWAYS be the same as the number of protons (which is the atomic number), so in this case the number of protons is 16, and that make the number of electrons 16
Answer:
The equation for acceleration can be rewritten as B to calculate the net force acting on an object when its mass and acceleration are known.
Explanation:
I hope that helps! (B is the answer)
Answer:
7.45
Explanation:
At 3.0 m PE = m*g*3.0, KE = m*g*(4.0 - 3.0)
At 2.0 m PE = m*g*2.0, KE = m*g*(4.0 - 2.0)
At 3.0 m PE = m*g*1.0, KE = m*g*(4.0 - 1.0)
At 0 m PE = 0, KE = m*g*h = total energy = 7.45 J
