Answer:
it shows the products of a chemical reaction to the right of the reaction arrow
Answer: Because new theories can come out that better explain observations and experimental results can replace old theories.
Explanation: Theories more than ten years old are usually out of date. Scientists want to prove that the work of other scientists is wrong. New evidence that supports a change prompts scientists to modify earlier theories.
Answer:
Explanation:
I can conclude that this means that the law can be broken under certain coditions as long as its not focused on a natural phenomonon
and a pheononmono is a fact or situation that is observed to exist or happen, especially one whose cause or explanation is in question.
Answer:
x=0.46m, speed=7.9m/s
Explanation:
Using the concept of conservation of energy:
1. kinetic energy of mass m and velocity v: 
2. gravitational potential energy of mass m, grav. acc. g and height h: 
3. potential energy in a spring with spring constant k and displacement from equilibrium x: 
Calculating x:


Calculating the speed:



Solving for
:

Answer:
t = 4.08 s
Explanation:
if the body is thrown upward, it has negative gravity. Knowing through the International System that the earth's gravity is 9.8 m/s²
Data:
- Vo = 40 m/s
- g = -9.8 m/s²
- t = ?
Use formula:
Replace and solve:
Time taken by it to reach max height is <u>4.08 seconds.</u>
