Answer:
Let's say a horse. In it's environment biotic factors such as predators and other animals that the horse competes with for food are limiting factors. Abiotic factors are the amounts of water, the temperature, and precipitation are also limiting factors.
Answer:
Option B. 1,100 Earth diameters
Solution:
Angular position of steroid,
(given)
To calculate the distance of asteroid, we use parallax method given as:
(1)
where,
From the relation:
l = ![\theta \times R](https://tex.z-dn.net/?f=%5Ctheta%20%5Ctimes%20R)
we get:
distance(d) or R = ![\frac{Earth diameter}{\theta}](https://tex.z-dn.net/?f=%5Cfrac%7BEarth%20diameter%7D%7B%5Ctheta%7D)
distance(d) or R = ![\frac{2\times radius of earth}{\theta}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%20radius%20of%20earth%7D%7B%5Ctheta%7D)
d = ![\frac{2\times 6350000}{8.726\times 10^{-4}}](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%206350000%7D%7B8.726%5Ctimes%2010%5E%7B-4%7D%7D)
distance, d = ![1.455\times 10^{10} m](https://tex.z-dn.net/?f=1.455%5Ctimes%2010%5E%7B10%7D%20m)
Comparing it with Earth's diameter:
d = ![\frac{1.455\times 10^{10}}{2\times 6350000} = 1,146](https://tex.z-dn.net/?f=%5Cfrac%7B1.455%5Ctimes%2010%5E%7B10%7D%7D%7B2%5Ctimes%206350000%7D%20%3D%201%2C146)
Since, the value is close to 1,100 Earth diameters, therefore, option B is the right answer.
Answer:
in series, R1 + R2 = RT
6 + R2 = 10
R2 = 4
IN SERIES COMBINATION,
CURRENT REMAINS THE SAME.
IT = VT/RT
IT = 20/10
= 2A
I remains the same in series, hence
I1 = 2A
I2 = 2A
V1 = I R1
= 2 x 6
= 12V
V2 = I R2
= 2 X 4
= 8V
P1 = I2R
= 2 X 2 X 6
= 24 W
P2 = I2R
= 2X 2X 4
= 16 W
TOTAL POWER = P1 + P2
= 40W

Answer:
![1650\:\mathrm{m}](https://tex.z-dn.net/?f=1650%5C%3A%5Cmathrm%7Bm%7D)
Explanation:
We can use the following kinematics equations to solve this problem:
.
Using the first one to solve for acceleration:
.
Now we can use the second equation to solve for the distance travelled by the airplane:
(three significant figures).
