Answer:
The internet is most useful to them because they use it to communicate.
Explanation:
If I were to send a message to my brother in Florida, through the internet, while I'm in Pennsylvania he would get it in minutes. On the other hand if I were going to meet him and then explain what I wanted to tell him in person it would take a much longer time.
Answer:
7.92 m/s
Explanation:
= Mass of raindrop = 
= Mass of mosquito
= Initial Velocity of raindrop = 8.1 m/s
= Initial Velocity of mosquito = 0 m/s
= Velocity of center of mass
For elastic collision
Hence, the velocity of the attached mosquito, falling immediately afterward is 7.92 m/s
Use the formula:
E = (1/2) * m * v ^2
For unit consistency, make sure that:
E energy is in joules (J)
m mass is in kilograms (kg)
v velocity is in meters per second (m/s)
So, substituting to the equation:
14= (1/2) * (17) * v^2
By algebraic manipulation, we derive:
v = (2*14/17)^0.5
v = 1.2834 m/s

They become flooded
Explanation:
Pavements using concretes and asphalts make water to runoff their surface. These surfacing materials prevents infiltration of water into the soil.
- Usually from every precipitation, a proportions goes into the soil as infiltration.
- Paved surfaces prevents infiltration of water into the soil.
- All the surface runoff will eventually move into nearby streams and rivers thereby increasing the volume of water in them.
- This enables rivers to become inundated and in the process they flood their banks and surrounding areas.

Answer:
The equation is missing in the question. The equation is 
a). 
, the horse will not turn.
b). a(t) = 10 + 18t
Explanation:
Given :
∴ At t =0, x = 10 m
a). Velocity as a function of time
= 
Turning velocity must be zero.
v(t) = 0
Taking the positive value of time.
The horse will not turn.
b). Acceleration as a function of time.
= 10 + 18t
∴ a(t) = 10 + 18t
