What is the persistent fear of snow falling

Answers

Chionophobia is the extreme dislike or fear of snow.

The word originates from Greek 'chion' meaning snow and 'phobos'
meaning fear, aversion or dread. People with Chionophobia often
understand that their fear is unfounded and weird. However, they
are unable to control it.

Another contributor was the first to answer the question correctly, and in fact,
I learned the answer from that earlier post.  If I could only remember who it was,
I would give them a big shout-out.  Their answer was deleted by a moderator

Which of the following statements is not true regarding atmospheric pressure?A. You calculate absolute pressure by adding atmospheric pressure to gage pressure.
B. When atmospheric pressure is higher than the absolute pressure of a gas in a container, a partial vacuum exists in the container
C. Mercury and aneroid barometers are used to measure atmospheric pressure.
D. Atmospheric pressure increases with increasing altitude

Answers

The correct answer is option B. i.e.When atmospheric pressure is higher than the absolute pressure of a gas in a container, a partial vacuum exists in the container. This is the incorrect statement about atmospheric pressure and the absolute pressure.

Which two changes would increase the electric force between two charged particles

Answers

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

If the amplitude of the resultant wave is twice as great as the amplitude of either component wave, and the wave exhibits reinforcement, the component waves mustA. Have a different wave length than the resultant wave
B. Be in phase with each other
C. Have a different frequency than the resultant wave
D. Be traveling in the opposite direction of the resultant wave

Answers

Correct answer choice is:

B. Be in phase with each other.

____________________________________________________________

Explanation:

Components waves mix to produce a resultant with the equivalent wavelength but the amplitude which is bigger than the amplitude of both of the unique component waves, and this results in constructive interference, which states that the interference of two or more waves of identical frequency and phase, constructing in their respective reinforcement and constructing a single amplitude equivalent to the total of the amplitudes of the unique waves.

Displacement vectors of 5 km north, 3 km east, 2 km south, and 3 km west combine to a total displacement of ___

Answers

The answer is A. 3 km north

Displacement (D) is the shortest distance from the initial to the final position.
In this example, distance is 5 km north - 2 km south = 3 km north (look at the image).
