Answer:
it is positive feedback loop
Explanation:
It's a phenomenon scientists call a positive feedback loop: deforestation causes drought, which in turn, worsens deforestation, and so on, intensifying the effect. The study concluded that deforestation causes 4% of drought, while drought accounts for 0.13% of deforestation per millimeter of rain in the Amazon biome.
Why are there 16 ounces in a pound but 14 pounds in a stone?
Answer:
The pound originally was 12 oz, but was increased to 15 and then 16 oz later. One should remember that the weights on the scales were marked in oz, of 1, 2, 4, 8, &c, and in one case, the 16 oz simply became the pound.

A taxi drives 300.0 m south and then turns and drives 180.0 m east. What is the total displacement of the taxi?
Please find attached photograph for your answer.
Hope it helps.
Do comment if you have any query.
The total displacement of the taxi is approximately 349.68 m.
To find the total displacement of the taxi, we can use the Pythagorean theorem since the south and east directions form a right triangle.
Given:
Distance traveled south = 300.0 m
Distance traveled east = 180.0 m
Treat the south direction as the negative y-direction and the east direction as the positive x-direction.
Using the Pythagorean theorem, the total displacement (D) is given by:
D = √((Δx)² + (Δy)²)
Where:
Δx is the change in the x-direction (east)
Δy is the change in the y-direction (south)
Let's calculate the total displacement:
Δx = 180.0 m (east)
Δy = -300.0 m (south)
D = √((180.0 m)² + (-300.0 m)²)
D = √(32400.0 m² + 90000.0 m²)
D = √(122400.0 m²)
D ≈ 349.68 m
Therefore, the total displacement of the taxi is approximately 349.68 m.

How much force, in N, must be applied to a 18-kg object in order to accelerate it at 5 m/s2?
Answer:
90 N
Explanation:
Given Information :Acceleration (a) = 5 m/s²Mass (m) = 18 kgTo calculate :Force (F)Calculation :★ F = ma→ F = 18 kg × 5 m/s²
→ F = 90 kg.m/s²
→ F = 90 N
Therefore, 90 N force is required.

A motorist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration? Is this acceleration higher than that of a car which accelerates from 0 to 30 m/s in 6 seconds?
Answer:
[tex]\boxed {\boxed {\sf \frac {8}{3} \ m/s^2 \ and \ not \ higher \ than \ the \ car's \ acceleration }}[/tex]
Explanation:
Acceleration is the rate of change of velocity with respect to time. It is calculated by dividing the change in velocity by the time.
[tex]a= \frac {v_f-v_i}{t}[/tex]
1. Motorist Acceleration
The motorist accelerates from an initial velocity of 0 meters per second to a final velocity of 8 meters per second in 3 seconds.
[tex]v_f[/tex]= 8 m/s [tex]v_i[/tex]= 0 m/s t= 3 sSubstitute the values into the formula.
[tex]a= \frac{ 8 \ m/s - 0 \ m/s }{3 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{8 \ m/s}{3 \ s}[/tex]
[tex]a= \frac{8}{3} \ m/s^2[/tex]
[tex]a \approx 2.667 \m/s^2[/tex]
2. Car Acceleration
The car accelerates from an initial velocity of 0 meters per second to a final velocity of 30 meters per second in 6 seconds.
[tex]v_f[/tex]= 30 m/s [tex]v_i[/tex]= 0 m/s t=6 sSubstitute the values into the formula.
[tex]a= \frac{ 30 \ m/s - 0 \ m/s }{6 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{30 \ m/s}{6 \ s}[/tex]
[tex]a= { 5 \ m/s^2}[/tex]
The motorist's acceleration is 8/3 or approximately 2.667 meters per second squared. This is not higher than the car's acceleration of 5 meters per second squared.
