Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become. Hope this helps please mark brainliest :)
Answer:
First one: group
Second one: period
Third one: number of valence electrons
Last one: increases
Answer:
Red, orange, yellow, green, blue, indigo, violet.
Explanation:
Answer:The higher the amplitude, the higher the energy. To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
Explanation:
Assuming ideality:
PV=nRT
Pv= (mass/molarmass)RT
Solve for the mass :-)
