Answer:
D. gravity, friction, and an applied force.
Explanation:
There are 4 forces that act on an airplane in motion and they are:
Gravity and drag:
It acts in a downward direction—toward the center of the Earth.
Lift:
It is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.
Thrust:
It is the force that propels a flying machine in the direction of motion.
The electronic configuration of a ground-state Cr-atom :
1s²2s²2p⁶3s²3p⁶4s²3d⁴
<h3><u>What are electronic configurations?</u></h3>
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.
