1. Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
2. Insulation helps to prevent that transfer of heat. Many different materials are used for insulation. Engineers often use fiberglass, wool, cotton, paper (wood cellulose), straw and various types of foams to insulate buildings. A layer of trapped air can serve as insulation, too!
3. I'm not sure. Sorry
We are given with the data that the angle of velocity is above the negative axis. hence, the angle lies in the second quadrant with negative x axis and positive y axis. In this case, the x component is -12 cos 60 equal to -6 m/s while the y-component is 12 sin 60 equal to 6 sqrt of 3 m/s.
Answer:
B cus is in the south but that pfp tho
I would say gas, but I don't know enough about plasma to put it out. It's definitely not solids or liquids because their molecules are too close together to move freely. Gas or plasma! Sorry that I'm not sure.
Potential energy is what something has energy of staying still. if a car was the the top of a hill that’s where it has the most potential. kinetic energy is energy in motion. as that car on the hill starts to roll down, the potential of it lowers as the kinetic raises
