Answer: I'm not sure, but I think it would be a <em>total lunar eclipse </em>
Answer:
Increase in total energy will be equal to the increase in the internal energy i.e 
Joules
Explanation:
Given
Weight of sledge hammer 
kilogram
Speed of sledge hammer 
meter per second
Kinetic energy is equal to half the product of mass and velocity square
Substituting the value of mass and velocity, we get -
It is given that one fourth of the energy is converted into internal energy
One fourth of kinetic energy is equal to
Increase in total energy will be equal to the increase in the internal energy i.e Joules
Explanation:
do we can say that the first step is finding the acceleration of the object. We do so by saying F = ma
so a = F/m
a = 500 m/s^2
we now have the time, acceleration and initial velocity.
so we can find the final velocity by using one of newtons equations which is: vf = vi + at
so:
vf = 0 + 500 × 12
vf = 6000
note that our initial velocity was zero since the object was initially at rest.
if you still have any doubt dont hesitate to ask for further help.
Answer:
A
Explanation:
because she wants to practice science and A is the practical option.
Answer:
the equilibrium constant is equal to 1 (i.e., the reactant and product concentrations are always equal).
Explanation:
ΔG is a symbol related to Gibbs free energy, which is a physical quantity related to thermodynamics. ΔG refers to the difference between the change in enthalpy (and sometimes entropy) and the temperature of a chemical reaction.
Gibbs free energy is very useful for measuring the work done between the reactants in a reaction. It is calculated using the formula: ΔG = change in enthalpy - (temperature x change in entropy).
The ΔG of a reaction would have a minimum value (zero), if the equilibrium constant is equal to 1 (that is, the concentrations of the reagent and the product are always equal).
