The grand canal was built to make easier the transportation of grains to the power center of north china.
<h3>How was the Grand Canal built?</h3>
The canal was built in order to connect the Yellow River in the north with the Yangtze River in the south. This canal is built for making easier the transportion of grain from the south to the centers of north China. The total length of the Grand Canal is 1,776 km.
So we can conclude that the grand canal was built to make easier the transportation of grains to the power center of north china.

Food chain: a series of organisms showing which organisms eat each other
Explanation:
We have a wave function: D(y,t) and we want to know some things about it. 1. The direction the wave is travelling is negative y direction or -y. 2. Since sound waves are longitudinal waves, this sound wave is oscillating along the y axis. 3. The wavelength we can get from k=2π/λ, k is the wave number, λ is the wavelength. So λ=2π/k=6.28/8.96=0.7 m. 4. Before i get the wave speed i will calculate the period of oscillation. It can be calculated from: ω=2πf where ω is angular frequency and f is wave frequency. So f=ω/2π=3140/6.28=500 Hz and the period is T=1/f=1/500=0.002 s. 5. Wave speed is v=λ*f= 0.7*500=350 m/s.
The approximate acceleration of the car would be <span>3.00
</span>How? We have to use the formula to find the velocity.
v = d/t = 120/6.32
v = 19
Then plug the factor into the acceleration formula to find the acceleration:
a = v/t = 19/6.32
a = 3.00
So, the approximate acceleration of the car would be 3.00
Answer:
8N/m
Explanation:
The elastic potential energy stored can be calculated using the equation:
elastic potential energy = 0.5 × spring constant × (extension)2
assuming it is not stretched beyond the limit of proportionality.
Then calculate using the values in the question:
100J = 0.5 × spring constant × 5²
200J = spring constant × 25
spring constant = 200J ÷ 25m²
spring constant = 8J/m²
spring constant = 8N/m
