The answer is D “the lake contains more mass and more heat than the cup of water”
Answer: B
According to Coulomb: Like charges repel each other; unlike charges attract. Thus, two negative or positives charges repel one another, while a positive charge attracts a negative charge.
We see that the only diagram who shows two like charges and their Electromagnetic Forces is B
It would be helpful if you can provide the chart or any additional information about the what Selma made. Anyhow, as I've searched on the internet, the answer is - Switch the stages "Evaluate the solution" and "Design a solution."
Answer:
Potential Energy
Explanation:
Potential energy is the energy stored in an object due to it's position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
Answer:
A final velocity that is faster than an initial velocity.
Explanation:
The acceleration of an object is given by :
Where
v is final velocity and u is initial velocity
t is time taken
If the final velocity is more than the initial velocity, the acceleration is positive. So, the correct option is (a).
