The x component of the force on an incline plane is m*g*cos(theta) and the y component is mg*sin(theta). The normal force or x component, keeps the object in contact with the plane, and the y component of the force is so we can solve speed, acceleration, distance travelled, etc for the object using conservation of energy.
Hope this helps. Any questions please just ask. Thank you.
The US Department of Energy has set its own targets to achieve 15% of the country's electricity from hydropower by 2030 — it is currently 7%. Elsewhere around the world, countries are pledging to meet more and more of their energy needs through renewable energy sources.
Answer: <u>Option A: </u>The gas and food are examples of energy.
Explanation:
Work and energy are inter-related. Energy is required to do the work. An equal amount of energy is converted into work. Work and energy have same units. The SI unit is Joule.
The gas and food are sources of energy. They act as fuel. This energy is utilized to perform work. The gas is used to run the car. The food is metabolized inside the body which is a source of energy and utilized to perform every day work.
Hence, The gas and food are examples of energy.
Solid, liquid, gas, and plasma. hope that helped
