- An electric heater works by passing a current of 100 Amperes though a coiled metal wire, making it red hot. If the resistance of the wire is 1.1 Ohms, what voltage must be applied to it? G:I=100A R=1.1Omega A U:square A=? E x=a. 14 8 =14 tx/m A 5. S: V A/=111V A
- A 12 Volt car battery pushes charge through the headlight circuit resistance of 10 Ohms. How much current is passing through the circuit? G:V=square A R=square A square E: V=Rarrow square = square = square square square S: (1) S: square A=square A
- What current flows through a hair dryer plugged into a 120 Volt circuit if it has a resistance of 25 Ohms? G:V=square A R=square A U:square A=? E :V=Rarrow square s :square 4y =(square 4y 1:(square 4) S: square A= square A
- An MP3 player uses a standard 1.5 Volt battery. How much resistance is in the circuit if it uses a current of 0.01 Amperes? G:V=1.5V A I=0.01A A U:R A/=? E :V=Rarrow boxed (R) = = square square square 5. A ) S: square A=square A
- A ball is tossed from an upper-story window of a building The ball is given an initial velocity of 8.20m/s at an angle of 21.0^circ below the horizontal. It strikes the ground 6 .00 s lat (a) How far horizontally from the base of the building does the ball strike the ground? 45.9m (b) Find the height from which the ball was thrown. 194 m (c) How long does it take the ball to reach a point 10.0 m below the level of launching? 1.16
