What cause the air current to curve?
soldi70 [24.7K]

The Coriolis force bends the air current.

Explanation:

  • Coriolis force is an inertial force that opposes or deflects the motion of a freely moving mass from its original path.
  • The Deflection of wind and ocean current on Earth are all the effect of coriolis force.
  • Such an effect is termed as Coriolis effect.
  • Coriolis force act to a particular point of reference and not beyond that.

Predict the dominant type of bonding by considering electronegativity.
Vlad1618 [11]
If the atoms that are bonding have identical electronegativities, then it's a completely nonpolar covalent bond. This doesn't happen in the real world unless the two atoms are of the same element. In a practical sense, any two elements with an electronegativity difference less than 0.3 is considered to be nonpolar covalent.
As the difference between the atoms increases, the covalent bond becomes increasingly polar. At a polarity difference of 1.7 (this changes depending on who you ask) we consider it no longer to be a covalent bond and to be the electrostatic interactions characteristic in an ionic compound.
Just so you know, you shouldn't take these values as exact. ALL interactions between adjacent atoms involve some sharing of electrons, no matter how big the difference in electronegativity. Sure, you wouldn't expect much sharing in KF, but there's a little sharing of electrons anyway. There's certainly no big cutoff that happens at a difference of 1.7 Pauling Electronegativity units.

An experiment was designed to test whether students could squeeze a clothespin more times in one minute after resting or after e
Rudik [331]

If a student rests and then squeezes a clothespin for one minute, will they be able to squeeze it more than someone that exercised before squeezing the pin for 1 minute?


Hope this helps!
