Q. Television sets sometimes use a rabbit ears antenna to the right. A rabbit-ears antenna consists of a pair of metal rods. The length of each rod can be adjusted to one quarter of a wavelength of an electromagnetic wave whos frequency is 125 Mhz. How long is each rod.
Q. A 26-kg girl is bouncing on a trampoline. During a certain interval after leaving the surface of the trampoline, her kinetic energy decreases to 210 J from 430 J. How high does she rise during this interval? Neglect air resistance.
A gasoline engine absorbs 2,600 J of heat and performs 1,000 J of mechanical work in each cycle. Find the total of heat expelled in each cycle.
Two insulated wires, each 2.50 m long, are taped together to form a two-wire unit that is 2.50 m long. One wire carries a current of 7A; the other carries a smaller current I in the opposite direction. The two wire unit is placed at an angle of 78..
To determine the location of her center of mass, a physics student lies on the lightweight plank supported by two scales 2.50 apart, as indicated . If left scale reads 300 , and right scale reads 122 .
Two 2.0cm x 2.0cm plates that form a parallel-plate capacitor are charged to (+/-) 0.708 nC.what are the electric field strength inside and the potential difference across the capacitor if the spacing between plates.
How many 185 W lightbulbs can you use in a 191 V circuit without tripping a 15 A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each lightbulb is 131 V.)
What is the kinetic energy of a 0.5-kg object moving at a constant speed of 2 m/s?
To estimate the muzzle speed of a blow dart, fire dart straight up into the air and time how long it takes to come back down. Roughly half of that time is the time for object to decelerate from its initial velocity to motionless. Estimation the in..
How does the magnitude of electrical force between a pair of charged objects change while the objects are moved twice as far apart? Three times as far apart.
How various g's of acceleration does the astronaut experience when the device is rotating at top speed? Each 9.80 m/s^2 of acceleration is 1 g.
Presume the child remains horizontal during the fall to the floor. Note that a more complicated fall could result in a head velocity greater or less than the speed you calculate.
A 21 kg solid door is 220 cm tall, 94 cm wide. What is the door's moment of inertia for rotation about the vertical axis inside the door, 17 cm from one edge.
Suppose a constant ratio of 13.60 counts per minute per gram of living matter. A sample of a petrified tree was found to give 1.8 counts per minute per gram. How old is the tree.
