Explanation:
Given the magnitude of the forces, 7N and 2N, the minimum combining force acting on the forces are when the force's is acting in opposite direction.
Magnitude of the force in opposite direction is 7N - 5N = 2N
The maximum combining force occurs when they act in the same direction. Magnitude of the force in the same direction is 5N+7N = 12N
Hence the range of magnitude requires is 2N≤F≤12N
Answer:
Thermal energy typically flows from a warmer material to a cooler material. Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation.
Explanation:
ion know...
So is light, but we don't use light either to power anything, even though we do know how to capture them and extract their energy.
The reason we don't use sound or light as sources of energy is because the amount of energy in the sound and light that surrounds us is pitifully small ... in the milliwatts or microwatts, whereas the things we build and operate with oil or electricity need watts or kilowatts to function.
1 watt of sound will drive you out of the room and wake the neighbors, and 1 watt of light ... if it all enters your eye ... can permanently damage your sight.
