1.) because then people can evacuate the area in the path<span> of the hurricane.
2.) </span><span>At higher altitudes, water vapor starts to condense into clouds and rain, releasing heat that warms the surrounding air, Which makes it rise as well. Warmer waters feed more energetic storms.
3.) </span> <span>A hurricane starts off as a series of thunderstorms which intensify as it moves over the warm and humid sea. The humidity is at a constant level and so it continues to grow over the sea. Any kind of decrease or increase in humidity can change the strength of a hurricane.
4.) </span><span>Actually, tropical cyclones need weak winds. If the atmospheric winds are even remotely strong, they will act to cut back the system and prevent the convection from wrapping around the center.

5.) That hard to tell, it could be too much. Though I am going to go with yes. Cyclones need weak winds and good amount humidity.</span><span>

Distance, since distance represents how far something has travelled, which would be in our case 2.5m.
The correct answer is letter A. 6 millimeters. <span>If an object 18 millimeters high is placed 12 millimeters from a diverging lens and the image is formed 4 millimeters in front of the lens, the height of the image is 6 millimeters.
</span>
Solution:
18 / x = 12 / 4
12x = 72
x = 6mm
Answer:
F_Balance = 46.6 N ,m' = 4,755 kg
Explanation:
In this exercise, when the sphere is placed on the balance, it indicates the weight of the sphere, when another sphere of opposite charge is placed, they are attracted so that the balance reading decreases, resulting in
∑ F = 0
Fe –W + F_Balance = 0
F_Balance = - Fe + W
The electric force is given by Coulomb's law
Fe = k q₁ q₂ / r₂
The weight is
W = mg
Let's replace
F_Balance = mg - k q₁q₂ / r₂
Let's reduce the magnitudes to the SI system
q₁ = + 8 μC = +8 10⁻⁶ C
q₂ = - 3 μC = - 3 10⁻⁶ C
r = 0.3 m = 0.3 m
Let's calculate
F_Balance = 5 9.8 - 8.99 10⁹ 8 10⁻⁶ 3 10⁻⁶ / (0.3)²
F_Balance = 49 - 2,397
F_Balance = 46.6 N
This is the balance reading, if it is calibrated in kg, it must be divided by the value of the gravity acceleration.
Mass reading is
m' = F_Balance / g
m' = 46.6 /9.8
m' = 4,755 kg
