Answer:
Technology to utilise the forces of nature for doing work to supply human needs is as old as the first sailing ship. But attention swung away from renewable sources as the industrial revolution progressed on the basis of the concentrated energy locked up in fossil fuels. This was compounded by the increasing use of reticulated electricity based on fossil fuels and the importance of portable high-density energy sources for transport – the era of oil.

Answer:
25v²
Explanation:
The kinetic energy in joules of a 50-kilogram runner running at v meters per second is modeled by the equation
Solution:
Kinetic energy is the energy of a body due to its motion. The kinetic energy of a body is maintained until there is a change in velocity. Kinetic energy can also be defined as the work done in accelerating a body from rest to a specified velocity. The SI unit is in Joules (J)
The formula for kinetic energy is:
K.E = (1/2)mv²
where m is the mass of the object and v is the velocity of the object.
Given that m = 50 kg and v = v, hence:
K.E = (1/2) * 50 * v² = 25v²
K.E = 25v²
The very beginning of the Preamble of the U.S. Constitution would suffice for reflecting the principle of popular sovereignty. “We the people.” These words show popular sovereignty by establishing the people’s rule for the government. “We the people” would be your answer.
Answer:
Climate
Explanation:
Climate is responsible for sparking hundreds of recent wildfires in California because due to climate change, the spark occurs in the dry grasses which catch fire and this fire spreads with the help of wind on thousand of acre and burn everything such as trees and vegetation etc. Due to this wildfires, the habitat of thousands of animals were destroyed and imbalance the whole ecosystem.
