If it's a distance graph, then it's a constant speed.
A is the answerrrrrrrrrrrr
Answer:
#_electrons = 2 10¹⁰ electrons
Explanation:
For this exercise we can use a direct rule of three proportions rule. If an electron has a charge of 1.6 10⁻¹⁹ C how many electrons have a charge of 3.2 10⁻⁹ C
#_electrons = 3.2 10⁻⁹ ( 
)
#_electrons = 2 10¹⁰ electrons
Answer:
1. 25%
2. You can move the skater higher up to increase the potential energy.
3. The kinetic energy increases because there is more motion.
Explanation:
1. If the total kinetic and potential energy is 100%, and we know that the kinetic energy is 75%, then we can find the potential by finding the missing value of this equation. Potential energy + kinetic energy =total energy.
? + 75%=100%
2. The higher an object is, the more potential energy it has because of the increase of its gravitational energy.
3. When an object is higher, there is more potential energy. As the skater goes down, the potential energy decreases which in turn increases the kinetic energy.
