Answer:
Climate scientists compare the tree growth records to local weather records. For locations where a good statistical match exists between tree growth and temperature or precipitation during the period of overlap, the ring widths can be used to estimate past temperature or precipitation over the lifetime of the tree.
A side of any triangle is less than the sum of the other two sides so the third side must be less than 24cm.
<h3>What is a triangle?</h3>
A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
In any triangle, the sum of two sides is always greater than the third side.
If the third side is equal to the sum of two sides then it will be a straight line rather than a triangle.
It means 10 + 14 > third side
24 cm > third side
Hence "A side of any triangle is less than the sum of the other two sides so the third side must be less than 24cm".

Answer:
As they travel through rock, the waves move tiny rock particles back and forth -- pushing them apart and then back together -- in line with the direction the wave is traveling. These waves typically arrive at the surface as an abrupt thud. Secondary waves (also called shear waves, or S waves) are another type of body wave

Explanation:
Gravitational Potential Energy can be calculated using the formula:
PE = mgh
where m is mass of object in <em>k</em><em>g</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>g is the gravitational acceleration of 10 m/s^2
h is the height at which object is thrown in <em>m</em><em>.</em>
Hence, by substituting in the values, we get:
GPE = (4.0)(10)(0.15)
<u>6</u><u> </u><u>J</u>
Hence, the potential energy is <u>6</u><u> </u><u>J</u><u>.</u>
Answer:
Angular momentum is conserved if there are no external forces
P1 = P2
I1 ω1 = I2 ω2
ω2 / ω1 = I1 / I2
If the skater pulls their arms in (I2 < I1) then the angular speed must increase for angular momentum to be conserved.
