The batteries in A flashlight rechargeable what energy conservation will have to take place in order to recharge the batteries.
vaieri [72.5K]

Example:

Solar energy ==> stored in chemical form in a tree as the tree grows

   Chemical energy in the wood ==>  released during burning

         Heat from the burning wood ==> absorbed by water,
                                                                 makes the water boil

               Steam holds great energy as heat,
                   steam pressure is used to turn a steam turbine

                     Kinetic energy of the turbine turns an electric generator

                         Electrical energy from the generator flows through
                              cables to your house, is available at outlets

                                  You plug your battery charger into an outlet,
                                       electrical energy flows through the charger 
                                       into the rechargeable batteries, where it is
                                       stored until you want to use it.

Calculate the momentum of a 4 kg Bolling ball being thrown at a speed of 3 m/s
bonufazy [111]

We are given –

  • Mass of boiling ball is, m = 4 kg
  • Speed is, v = 3 m/s
  • Momentum, P =?

As we know –

↠Momentum = Mass × Speed(Velocity)

↠Momentum = 4 × 3 kgm/s

↠Momentum = 12 kgm/s

  • Henceforth,Momentum will be 12 kgm/s.

An old fashioned string of 80 Christmas lights is wired in series. Each bulb has a resistance of 2 Ohms and the entire string is
34kurt

The sum of the resistance = 2 ohms x 80 lights = 160 ohms.

Current = Total voltage / total resistance:

Current = 120V / 160 ohms

Current = 0.75 Amps
