Answer:
1250joules
Explanation:
The kinetic energy is energy in motion and it's formula is
KE =1/2MV^2
M represent mass which is 100Kg.
V represent velocity which is 5m/s
Therefore, KE = 1/2×100×5× 5
= 50 × 25
KE= 1250joules
The location of reduction in an electrochemical cell is called the anode.
An electrochemical cell ( galvanic cell ) is generate electric energy from chemical reactions. In galvanic cell species ( for example zinc and zinc cations ) from one half-cell lose electrons ( oxidation ) and species from other half-cell ( for example copper and copper cations ) gain electrons ( reduction ). Electric current is generated due to the flow of electrons from the anode that undergoes an oxidation reaction to the cathode which has a reduction reaction in the circuit of an outer wire circuit.

It depends on other factors to. techniqually this doesent take place in time so it could be that in the future that will be enough but you are probably right. most appliances could not heat water with .1 lb of propane. though it would be luke warm
Answer:
c. composed of only one type of atom or molecule.
Explanation:
Pure substances are the substances that could be made up of only one type of particles and also it contains fixed structure. They would be further categorized as the elements & compounds. It is an elements that only consist of only one type of atom or molecule
Therefore as per the given situation, the option c is the answer
