Answer:
distance between school and home is 21 miles
Explanation:
given data
in rush hour speed s1 = 28 mph
less traffic speed s2 = 42 mph
time t = 1 hr 15 min = 1.25 hr
to find out
distance d
solution
we consider here distance home to school is d and t1 time to reach at school
we get here distance equation when we go home to school that is
distance = 28 × t1 .......................1
and when we go school to home distance will be
distance = 42 × ( t - t1 )
distance = 42 × ( 1.25 - t1 ) ...................2
so from equation 1 and 2
28 × t1 = 42 × ( 1.25 - t1 )
t1 = 0.75
so
from equation 1
distance = 28 × t1
distance = 28 × 0.75
distance = 21 miles
The choices can be found elsewhere and as follows:
A anthropocentric
B frontier
C land
D biocentric
I think the correct answer is option A. It is anthropocentric the type of ethic that is life-centered and views humans as just one component life on Earth. Hope this answers the question. Have a nice day.
Answer:
Mass of the sled in the snow 83.33 kg.
<u>Explanation</u>:
Given that,
Force applied to move the sled in the snow (F) = 75N
![\text { Acceleration }(a)=0.9 \mathrm{m} / \mathrm{s}^{2}](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Acceleration%20%7D%28a%29%3D0.9%20%5Cmathrm%7Bm%7D%20%2F%20%5Cmathrm%7Bs%7D%5E%7B2%7D)
We know that
Newton's second law of motion is
![\text { Force }=\text { mass } \times \text { acceleration }](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Force%20%7D%3D%5Ctext%20%7B%20mass%20%7D%20%5Ctimes%20%5Ctext%20%7B%20acceleration%20%7D)
F = ma (Or "force" is equal to "mass" times "acceleration".)
So if we move this around we can isolate mass and get mass
![\text { Mass }=\frac{\text { force }}{\text { accelearation }}](https://tex.z-dn.net/?f=%5Ctext%20%7B%20Mass%20%7D%3D%5Cfrac%7B%5Ctext%20%7B%20force%20%7D%7D%7B%5Ctext%20%7B%20accelearation%20%7D%7D)
![\mathrm{M}=\frac{75}{0.9}](https://tex.z-dn.net/?f=%5Cmathrm%7BM%7D%3D%5Cfrac%7B75%7D%7B0.9%7D)
M = 83.33 kg
Mass of the sled in the snow <u>83.33 kg.</u>
Answer: 131.14km per day
Explanation: since the second half of the terns migration takes 122 days we can assume that the full migration would take 244 days. using this we can divide the total distance by the total amount of days it takes (because speed = distance/time) which is 32,000/244, which would be 131.14
