Power = (work done) / (time to do the work)
Work done = (force to lift the object) x (distance lifted)
In this question, the force is the (weight of the basket)+(your weight).
Work done = (weight of basket+you) x (3 meters)
Time to do the work = 6 seconds.
Power = (weights x 3 meters) / (6 seconds)
<em>Power = (1/2)·(weight of the basket+you, in Newtons) watts</em>
Answer:
coal, oil and natural gas.
Explanation:
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
Explanation:
The Hubble telescope was launched in 1990, in the low Earth orbit and remains in operation. It was built by NASA with contributions from European Space Agency. There was a serious problem with the optical system and the analysis showed that the cause is the primary mirror that had been polished to the wrong shape, introducing spherical aberration. It was solved by sending servicing mission in 1993, by installing a set of specialized lenses to correct the flawed main mirror in the telescope. Including this, there have been total five astronaut servicing mission to Hubble.
Highly
Explanation:
An atom that has one electron in its valence electron shell is highly chemically reactive.
Such atoms are called Alkali metals. They occupy the first group on the periodic table and they are a bunch of metals.
- The number of electrons in the valence shell of atoms determines the reactivity of an element.
- Atoms are gained or lost or shared in order to attain an octet configuration.
- When an atom with one electron in the valence shell loses this electron, it will become stable.
- This implies that it will attain its octet.
- This makes them take part in reactions that will ensure they lose that electron.
- Examples of such atoms Li, Na, K, Rb, Cs and Fr.
