The answer is: Renewable energy resource.
The explanation for this completion exercise is shown below:
By definition, the Renewable energy is that the energy that is obtained from renewable resources. Renewable energy sources has taken on importance in recent years and plays an important role in the sustainable development of the planet.
Therefore, Agricultural waste used as fuel is an example of a Renewable energy resource, because you can obtain low emissions but high efficiency.
Answer:
v = 44.27 m / s
Explanation:
This is an exercise in kinematics since they ask the maximum speed of the train
v² = v₀² + 2 a x
a train departs with zero initial velocity
v² = 2 a x
v = √ 2ax
calculate
v = √ (2 1.21 810)
v = 44.27 m / s
in this solution we have assumed that the train uses the entire distance with acceleration
The equatorial radius of the earth is
r = 6378 km = 6378 x 10³ m
The earth makes 1 revolution in 24 hours.
The angular velocity is
ω = (2π rad)/(24*3600 s) = 7.2722 x 10⁻⁵ rad/s
The tangential velocity (linear velocity) at a point on the equator is
v = rω
= (6378 x 10³ m)*(7.2722 x 10⁻⁵ rad/s)
= 463.8 m/s
Answer: 463.8 m/s
