Answer:
1. The precession of the equinoxes.
2. Changes in the tilt angle of Earth’s rotational axis relative to the plane of Earth’s orbit around the Sun.
3. Variations in the eccentricity
Explanation:
These variations listed above; the precession of the equinoxes (refers, changes in the timing of the seasons of summer and winter), this occurs on a roughly about 26,000-year interval; changes in the tilt angle of Earth’s rotational axis relative to the plane of Earth’s orbit around the Sun, this occurs roughly in a 41,000-year interval; and changes in the eccentricity (that is a departure from a perfect circle) of Earth’s orbit around the Sun, occurring on a roughly 100,000-year timescale. which influences the mean annual solar radiation at the top of Earth’s atmosphere.
Answer:
ΔL =0. 000312 m
Explanation:
Given that
At room temperature ( T = 25 ∘C) ,L= 1 m
So the length at 13.0 ∘C above room temperature
L=1.000312 m
So the change in length
ΔL = 1.000312 - 1.0000 m
ΔL =0. 000312 m
Answer:
Our final answer is option (c) that is :
A resonant mode of your vocal tract.
Explanation:
Lets understand pitch of a sound first:
Pitch: Is the rate of vibrations produced and also the degree of lowness and highness of a tone.
Pitch formant:
When we take air inside our vocal tract it oscillates at different pitches depending upon the cast and capacity of the opening of the vocal tract.
Formant comes from the vocal tract and also at a resonance of our vocal tract.
So basically the vocal tract play a vital role for the formant.
Final answer is : A formant is a resonant mode of our vocal tract.
A spring is an object that can be deformed by a force and then return to its original shape after the force is removed.Springs come in a huge variety of different forms, but the simple metal coil spring is probably the most familiar. Springs are an essential part of almost all moderately complex mechanical devices; from ball-point pens to racing car engines.
If an object's first movement is 3.0m North and another movement is 4.0m west, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
<h3>What is displacement?</h3>
Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.
As given in the problem if an object's first movement is 3.0m North and another movement is 4.0m west
Resultant displacement can be calculated with the help of the triangle law of the vector addition,
Resultant = √( 3² + 4²)
=√25
= 5.0 m
Thus, the magnitude of the overall displacement made would be 5.0 meters in the northwest direction.
