An electricity company wants to reduce wasted energy across a town. For the same amount of money, they can either: Use 20% of the wasted
energy from the power station to heat their offices. Install new power
lines which only waste half the energy of the old ones. Replace all the
bulbs in the town with LED bulbs, which are 99% efficient. Explain which of
these things they should do.

What must be the same for any two resistors that are connected in series ? a. the potntial diffrence across each b. the rate at which charge moves through each c. the rate at which energy is used by each d. the resistance to the flow of charge of each

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

Pl asaaap ! match the term to the correct description. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. movement that is like a t transfers energy from one location to another 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
