Six objects are placed in a 500^ \circ \rm F (260^ \circ \rm C) oven and allowed to reach thermal equilibrium. Each object has a mass of 1.0 {\rm kg}. The specific heat and thermal conductivity of each substance are denoted by c and k respectively.

Part B:

When removing the objects from the oven, you accidentally touch each one with your hand. Rank these objects on the basis of how hot they feel.
 
Rank from largest to smallest. To rank items as equivalent, overlap them.

Part C:

Each of the objects is immediately dunked in an identical tub of cold water. The tubs are quickly sealed and insulated. Rank the objects on the basis of their temperature on reaching equilibrium with the water.

Rank from largest to smallest. To rank itens as equivalent, overlap them.

The figure shows angular position versus time grap

a) Rank these graphs on the basis of the angular velocity of each object. Rank positive angular velocities as larger than negative angular velocities. Rank from largest to smallest. To rank items as equivalent, overlap them.

b) Rank these graphs on the basis of the angular acceleration of the object. Rank positive angular accelerations as larger than negative angular accelerations. Rank from largest to smallest. To rank items as equivalent, overlap them.

 

Five identical quintuplets leave earth when they reach the age of 21, in the year 2121. Each quintuplet goes on a spaceship journey that takes T years, as measured by a clock in each spaceship. During the journey, they travel at a constant speed v, as measured on earth, except during the relatively short acceleration phases of their journey.

Part A. Rank these quintuplets on the basis of the year on earth when they return from their journey. Rank from largest to smallest. To rank items as equivalent, overlap them.

A: T=20 years, v=0.4c

B: T= 5 years, v=0.2c

C: T=10 years, v=0.8c

D: T=10 years, v=0.4c

E: T=20 years, v=0.8c

 

Part B. Rank these quintuplets on the basis of their age when they return from their journey. Rank from largest to smallest. To rank items as equivalent, overlap them.

A: T=20 years, v=0.4c

B: T= 5 years, v=0.2c

C: T=10 years, v=0.8c

D: T=10 years, v=0.4c

E: T=20 years, v=0.8c

Six boxes held at rest against identical walls.
Rank the boxes on the basis of the magnitude of the normal force acting on them.
Rank from largest to smallest. To rank items as equivalent, overlap them.

1.)130N--->7kg
2.)150N--->1kg
3.)150N--->7kg
4.)120N--->3kg
5.)140N--->5kg
6.)140N--->3kg
(Since the boxes are at rest, Newton's 2nd law dictates that the horizontal forces on each box must add up to zero. You can use this information to determine the normal forces. If two boxes are both pushed against the wall by the same force, then they should experience the same normal force.)
 
Part B.) Rank the boxes on the basis of the frictional force acting on them.
Rank from largest to smallest. To rank items as equivalent, overlap them.
1.)130N--->7kg
2.)150N--->1kg
3.)150N--->7kg
4.)120N--->3kg
5.)140N--->5kg
6.)140N--->3kg
