The earth has a radius of 6380 km and turns around once on its axis in 24 h. (a) what is the radial acceleration of an object at

S_A_V [24]

<span>we know that<span>

a = ω²r
r = 6380 km----------- > 6.38e6 m
ω=2π/86400 sec </span></span>
<span>a=(2π/86400) ² (6.38e6 m )------------ > 0.03374
<span>
a = 0.03374 m/sec² </span></span>

if g------------------- > 9.8 m/sec² <span>
X----------------------> 0.03374 m/sec² </span>
X=0.03374 /9.8---------- > 0.00344 <span>
a = 0.00343 g </span>

the answer is
a = 0.03374 m/sec²
a = 0.00343 g

ABCD, GB is parallel to AK, AC is congruent to DB, GB is perpendicular to BD, KC is perpendicular to AC

AleksandrR [38]

Answer:

The two column proof is given as follows;

Statement ${}$ Reason

1. $\overline {ABCD}$ , $\overline{GD}$ \\ $\overline {AK}$ , $\overline{AC}$ ≅ $\overline {DB}$ ${}$ Given

$\overline{GB}$ ⊥ $\overline {BD}$ , $\overline{KC}$ ⊥ $\overline {BD}$

2. ∠KCA = ∠GBD = 90° ${}$ Given

3. Therefore,

4. ∠KAB = ∠GDC ${}$ Alternate interior angles

5. ΔGBD ≅ ΔKCA ${}$ By ASA rule of congruency

6. $\overline{GB}$ ≅ $\overline {KC}$ ${}$ By CPCTC

Explanation:

Given that two angles and an included side of triangle ΔGBD are equal to the corresponding two angles and an included side of triangle ΔKCA, therefore, ΔGBD ≅ ΔKCA by the Ange-Side-Angle rule of congruency, therefore, we have;

Segment $\overline{GB}$ is congruent to segment $\overline {KC}$ by Congruent Parts of Congruent Triangles are Congruent, CPCTC.

The Earth's precession has caused the North Pole to point to other stars besides Polaris in the past

Alenkasestr [34]

Answer:

<u>True</u>

Explanation:

The spinning of the earth on its axis has led to the stars to travel across the sky in a circular direction, as when you reach the north pole the stars appear directly above us as the atmosphere is less dense and more clear.

This is defined as the axial precession is slow, gravity-induced and changes in the order of astronomical body rotation. Also known as the precession of the equinoxes, discovered in 1929.

Polaris being a north pole star, the brightest star in the constellation. Standing almost motionless in the northern hemisphere. And s about 433 light-years away from being a yellow supergiant it's in precession with that of earth. It is 2.5 brighter than today as in Ptolemy time.
