is this right??
Select the choices in which work is done by recording "yes" or "no":
a. Reese completing her chemistry homework
b. the movers carrying Catalina's amplifier from the moving truck to her house
c. Li pushing his motorcycle down his driveway
d. Reese carrying several encyclopedias
e. Catalina picking up a piece of sheet music from the floor
f. Cory pushing a stalled car but unable to get it to move
g. pushing a science book along a table
my answers
a. yes
b. yes
c. yes
d. yes
e. yes
f. no
g. yes
I assume this is a physics question...
Work is applying a force to cause a displacement (W=F*s)
So, in any of your examples, if there is not both force and displacement, it's not considered work. So, I would say...
a. no
b. yes
c. yes
d. yes
e. yes
f. no
g. yes
