Answer:
a). Roger travel total a distance of 2070m
b). The average speed of the whole tip
0.16025
Explanation:

a).
First trip 450m
Second trip :

So final distance is
450m+1620m=2070m
b).

The average speed is
0.10625 
Answer:
Explanation:
a ) The earth rotates by 2π radian in 24 x 60 x 60 s
so angular speed ( w ) = 2π / (24 x 60 x 60) = 7.268 x 10⁻⁵ rad / s
b ) Linear speed of city of Arlington ( v ) = w r = w R Cosλ where R is radius of the earth and λ is latitude .
v = 7.268 x 10⁻⁵ x 6.371 x 10⁶ cos 32.7357
389.5 m /s
acceleration = w² r = w² R Cos 32.7357
= (7.268 x 10⁻⁵ )² x 6.371 x 10⁶ x cos 32.7357
=283.08 x 10⁻⁴ m/s²
c) velocity ratio =
w r /w R =
R cos 32.73/ R
= Cos 32.73
= 0.84 .
The answer is true. scarcity exists because the resources are being depleted to meet the increasing demands of the people
The answer that I got was 5'8333..., which is the total for height and in inches, all of this would be 70 inches, or 1.78 meters, or 178 centimeters, or 1780 millimeters, but just go for the height that person is going to be at, 5'833... (this is repeated so just round it up to 5'8 if you want to.)
Hope this helped!

Answer:
The ocean tides on earth are caused by both the moon's gravity and the sun's gravity. ... Even though the sun is much more massive and therefore has stronger overall gravity than the moon, the moon is closer to the earth so that its gravitational gradient is stronger than that of the sun.
