Answer:
Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
Explanation:
Answer: 270 km
Explanation:
3 cm/80 km :: 10 cm/(x)km
cross multiply
3x = 80(10)
x = 800/3 = 266.66666... ≈ 270 km

I believe it's True! Brainliest??
Explanation: Hope you have a great day :)
The final common speed of the two carts will be 69.3 m/sec.The momentum conservation principle is applied.
<h3>What is the law of conservation of momentum?</h3>
According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
Unit conversion:
1 metric tons = 1000 kg
Given data;
m₁= 11.6 metric ton =11600 kg
m₂ = 23.2 metric ton = 23200 kg
Let v represent the combined velocity of the two carts once they are connected, and let u represent the starting velocity of cart 1 when it reaches the bottom.
Considering energy conservation;

From the conservation of momentum principle;

Hence, the final common speed of the two carts will be 69.3 m/sec.
