2024 WGU C165 Unit 5 Earth & Sky New Full Questions and Answers ( Included ) 100% Correct 1. Newton's Law of Universal Gravitation Answer: The law that says every object in theuniverse attracts every other object, and that the force is affected by mass and distance: the greater the mass of an object, the greater the attraction; the farther apart the objects, the weaker the attraction. 2. Nebula Answer: a cloud of gas and dust in space 3. Nuclear Fusion Answer: The process by which ...

Lights acts as what? - Answer-Particle and wave. Wavelength - Answer-The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) - Answer-The number of wavefronts per second. Highest: x-ray Velocity of Light - Answer-C = 3.00 X 10^8 = wavelength X frequency Amplitude - Answer-The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) - Answer-Increases as frequency increases and as wa...

Give the full electron configuration of an Al atom and a Cr3+ ion : 1s2 2s2 2p6 3s2 3p1 1s 2s2 2p6 3s2 3p6 3d6 Deduce the formula of the ion that has a charge 2+ with the same electron : Sr2+ Deduce the formula of the compound that contains 2+ ions and 3- ions that both have the same electron configuration as argon : CaP Deduce which of Na+ and Mg2+ is the smaller ion 2 marks : Mg 2+ Both have the same number of shielding however Mg2+ has more protons so higher nuclear charge and so...

Which reaction requires the most energy? A. N(g) → N+(g) + e - B. N+(g) → N2+(g) + e - C. F(g) → F+(g) + e - D. F+(g) → F2+(g) + e - - Answer-D. F+(g) → F2+(g) + e - Fluorine has a higher effective nuclear charge than Nitrogen - so it is harder to remove an electron (takes more energy because the electron is more strongly attracted by the nucleus). Effective nuclear charge is the same for F and F+ because the number of protons and core electrons are not changed. However, when t...
