Answer:
The Fertile Crescent was good for farming because of the fertility of its land, a result of irrigation from numerous large rivers in the region.
Explanation:
Answer:462400joules
Explanation:
Mass=m=800kg velocity=v=34m/s
Kinetic energy=(m x v^2)/2
Kinetic energy =(800x34^2)/2
Kinetic energy =(800x34x34)/2
kinetic energy =924800/2
Kinetic energy =462400joules
Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. ... They are hence known as 'electromagnetic' waves. The electric field and magnetic field of an electromagnetic wave are perpendicular (at right angles) to each other.
Hope this helps.

The average acceleration of the car as it accelerates from 15 m/s to 25 m/s will be 2.5 m/s².
<h3>What is Average acceleration?</h3>
Average acceleration is the average rate of change of velocity with respect to time. Mathematically -
a = Δv/Δt
Given that a car is traveling at 15 m/s in north direction and in 4 seconds it accelerates to 25 m/s in the north direction only. Therefore, we can write -
initial velocity [u] = 15 m/s
final velocity [v] = 25 m/s
time taken [Δt] = 4 s
The magnitude of the average acceleration can be calculated as follows-
a = Δv/Δt
Δv = v - u = 25 - 15
Δv = 10 m/s
Therefore -
a = 10/4
a = 2.5 m/s².
Therefore, the average acceleration of the car will be 2.5 m/s².
