Anyone can help me solve 2 of those problems

A man lifts a box of books that weigh 185N. The box is lifted 0.80m. How much work does the student do on the box?

A thermometer can measure temperature to the nearest enth of a degree. Which of the following readings gives the temperature to the accuracy of the thermometer?
a) 67.43
b) 67
c) 6.743x10^1
d) 67.4
e) None of these

• Physics -

The man exerts a force of 185 Newtons up.
The box moves .8 meters up
The work done = .8*185 newton meters which is called Joules

• Physics -

Only d is to a tenth of a degree.
A is to a hundredth
B is to a whole degree
C is to a hundredth (It is really the same a A)

thanks a lot
