Mass of the object is given as
now the speed of object is given as
here we know that
now we will have
now we will have kinetic energy of the object as
now the power is defined as rate of energy
so here we can find power as
so above is the power used for the object
I believe the answer is 7.24 kJ.
From the equation ΔE = dW + dQ; where W is the work done on/by the system and Q is the heat the system absorbs/loses.
Therefore; ΔE = 72.4 kJ since the system has bot done any p-v work (dV= zero) and has absorbed heat.
The answer is A: Core --> Mantle --> Crust.
Core: The earth's core is the center of the earth, which would ultimately be the deepest. The core is made up of alloy, which is a mixture of many medals, such as iron and nickel.
Mantle: The earth's mantle is the layer between the earths crust and core. Often made of silicate rocks.
Crust: The earth's crust is the outer-most of the three options. Usually made of up different types of rocks.
The correct answer is B) Measures of variability. Hope this helps.
Answer:
Nuclear Reaction
Explanation:
Technically fusion and fission should be included, but a nuclear reaction includes both fusion and fission, so it must be the answer.
