[Sagot para sa’yo] Hihii I have a project where we have to come up with solutions, or at least something that could help with the effects of typhoons. Me and my groupmates fell short and came up with vetiver grass after researching a bit. We're planning on comparing it with two other types of grass and placing all three types of grasses in different types of soil. The problem now, is that my teacher wants me to complicate the project so it's not too "elementary-level" by tomorrow.​

[Sagot para sa’yo] A. THINK TANK! Write True if the statement is correct, but if it's False, change the underlined word or group of words to make the whole statement true. Write your answers on your science notebook. 1. Mechanical energy consists of two types, the potential energy and kinetic energy. 2. Potential energy is energy due to its high velocity. 3. Kinetic energy is also termed as stored energy. 4. Given that PE is 50 J and KE is 10 J, then the total ME is 40 J. 5. ME is the product of PE and KE. 6. The object's kinetic energy is transformed into potential energy or vice versa. 7. When Potential Energy of a pendulum decreases as it swings down, Kinetic Energy increases as it gains speed. 8. At a point, Potential Energy is zero while Kinetic Energy is at its maximum. 9. When the vehicle is moving, there is a gain of potential energy. 10. When the vehicle is at rest, it has kinetic energy.​
