Answer:
Nickel has an atomic number of 28,so it has 28 electrons
Nickel has 10 valence electrons
The Outer space of the colder region has the temperature of 2 Kelvin.
<u>Explanation:</u>
Even the sun is in extreme hot condition or temperature, but the outer space or called as space is extremely cold that is around 2 Kelvin.
In the space there are no objects or nothing to make the heat to travel through, even though the sun's heat travels in space there will be nothing like molecules or atoms are there to transfer or absorb it. So, at the outer regions of colder space the temperature is only 2 Kelvin.
Answer:
Gravitational potential energy of water behind the dam
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Hydroelectric power plant refers to a renewable source of energy used for the generation of electricity, through the use of powerful hydraulic steam turbines operating at high voltage and are being driven by the energy acquired by water falling from a height and flowing through a penstock (pipe) i.e the mechanical energy (gravitational potential energy + kinetic energy).
At a hydroelectric power plant, potential energy is changed into kinetic energy. The kinetic energy is then transformed into electrical energy.
The source of the energy that turns the turbine in the power plant is Gravitational potential energy of water behind the dam, usually from streams or rivers.
C,
takes dead things, makes them into other things
The ideal gas law states:
If we put in the data.
Hope this helps.
