To understand the meaning and possible applications of the work-energy theorem.
rosijanka [135]

Answer:

   <u> a = V final 2___v initial2</u>

                      28

Explanation:

By definition for contant acceleration        <u>a =   V final ___v initial</u>

                                                                                      t

Furthermore the average speed is           <u>V abg =  v initial +v final</u>

                                                                                         2

Combine these relationships to eliminate t.               8 = Vabg t.

What is the energy of a baby who weighs 20 N sitting on a 1.5 m high chair
guajiro [1.7K]
The energy of the baby is gravitational potential energy, and it is equal to the weight of the baby times its height from the ground:
U=(mg) h
where
mg=20 N is the weight (the mass times the gravitational acceleration)
h=1.5 m is the height from the ground
If we plug the numbers into the equation, we find
U=(mg)h=(20 N)(1.5 m)=30 J

Answer:

  • toaster -- 15 A, 8 Ω
  • fry pan -- 10.83 A, 11.08 Ω
  • lamp -- 0.83 A, 144 Ω
  • fuse will blow

Explanation:

  P = VI

  I = P/V = P/120

  R = V/I = V/(P/V) = V^2/P = 14400/P

<u>Toaster</u>: I = 1800/120 = 15 . . . amps

  R = 14400/1800 = 8 . . . ohms

<u>Fry pan</u>: I = 1300/120 = 10.833 . . . amps

  R = 14400/1300 = 11.08 . . . ohms

<u>Lamp</u>: I = 100/120 = 0.833 . . . amps

  R = 14400/100 = 144 . . . ohms

The total current exceeds 20 A, so will blow the fuse.
