Explanation:
Antoine lavoisier is most famous for his role in discovering of oxygen. He recognized and name two important element oxygen(1778) and hydrogen(1779).
In a chemical reaction, Lavoisier observed the mass is retained. A chemical reaction's total mass of the products will always be the same as the total mass of the reactant materials used in the reaction. His results led to one of the basic laws of chemical behavior: the law of material preservation, which states that matter is preserved in a chemical reaction.
Answer:
Elements are made up of only one type of atom. Each element has a unique chemical symbol. Elements can be identified by their atomic number.
Assuming is a closed circuit when the switch is closed, it would be the strength of the battery in the circuit, assuming a and b were points at each end of the circuit. Depending on the specifics of the circuit, this could change, you could add more batteries together or it could reduce based on resistance if there's a viable current path still open while the switch is open. You may have missed attaching a picture or link.
Answer:
1.28 m, 14 m/s
Explanation:
At the maximum height, the velocity is 0.
Given:
a = -9.8 m/s²
v₀ = 5.00 m/s
v = 0 m/s
x₀ = 0 m
Find:
x
v² = v₀² + 2a(x - x₀)
(0 m/s)² = (5.00 m/s)² + 2(-9.8 m/s²) (x - 0 m)
x = 1.28 m
The maximum speed is at the bottom of the well.
Given:
a = -9.8 m/s²
v₀ = 5.00 m/s
x₀ = 0 m
x = -8.5 m
Find:
v
v² = v₀² + 2a(x - x₀)
v² = (5.00 m/s)² + 2(-9.8 m/s²) (-8.5 m - 0 m)
v = -13.8 m/s
Rounded to 2 sig-figs, the maximum speed is 14 m/s.
'Greater' or 'smaller' means whatever the force is right now would change.
In order to figure out how it would change, we would need to know what
the cube is surrounded by right now, before it goes into the water.
What I'm really trying to say is: There's not enough information in
the question for us to be able to answer it.
