Answer:
LED ligths produce less heat and more ligth.
Explanation:
Incandescent bulbs transform 88% of their energy in form of heat, but not in ligth, however LED ligth bulbs transform 88% of their energy in visible ligth (in particular visible wavelengths), so they are more eficcients.
Answer:
Principles of Simple Machines: Machines simply transmit mechanical work from one part of a device to another part. A machine produces force and controls the direction and the motion of force, but it cannot create energy. A machine's ability to do work is measured by two factors.
Explanation:
Answer:
the hypotenuse = 13.78 cm
Ф = 27.44°
θ = 62.56°
explanation:
Answer:
Well that depends on the force that is being applied onto the table and how much is being forced back
Explanation:
When learning about net force there should be some numbers with a N next to them showing you the direction of the newtons. In order to solve this problem and figure out the net force you have to subtract the newtons ( larger number first no negative newtons) then the largest newton after the subtraction the direction is the same direction as the biggest number
Example: 20N⬆️
30N⬇️
Subtract 30-20=10N⬇️
