1. A 250.0 g metal block absorbs 7.849 × 10 3 J of heat to raise its

 

temperature by 35.0 K. What is the substance? Show your work.

 

Specific Heats of Selected Substances

 

Substance

 

Water (ice) C [J/(kg·K)]

 

2,060 Iron 450 Aluminum 897 Gold 130 Copper 385 Silver 235 Ammonia (liquid) 4,700 Water (liquid) 4,180 Water (steam) 2,020 Lead 2. 128 A 12.0 V battery is hooked up with three resistors (R1, R2, and R3) in parallel

 

with resistances of 2.5 ?, 7.0 ?, and 15.0 ?, respectively.

 

a.) Draw a labeled circuit diagram for the circuit described using correct

 

symbols.

 

b.) Calculate the equivalent resistance.

 

c.) Calculate the current passing through each resistor in the circuit. 3. A block and tackle is used to raise a 72.0 N crate 12.3 m from the loading

 

dock to the ship. This requires a force of 25.0 N to be applied by the

 

longshoreman.

 

a.) What is the mechanical advantage of the block and tackle?

 

b.) How much rope must be pulled? Note: Assume that IMA = MA.

 

c.) The longshoremen have only a 40 m rope that they are told not to

 

cut. They use this for the block and tackle. How does this affect the

 

efficiency of the block and tackle? 4. A 650.0 kg roller coaster car is at rest at the top of a 75 m hill. It rolls down

 

the first drop to a height of 28 m. When it travels to the top of the second hill,

 

it is moving at 23.5 m/s. It then rolls down the second hill until it is at ground

 

level. Draw a picture of the roller coaster drop and calculate the kinetic and

 

potential energy at the top and bottom of each hill. 5. A 2.4 cm object is 15.0 cm to the left of a convex lens with a focal length of

 

+5.0 cm.

 

a.) Draw a ray diagram of the setup showing the location of the image.

 

b.) Calculate the distance of the image from the lens.

 

c.) What size is the image and is it upright or inverted?
