Aloaded grocery cart is rolling across a parking lot in a strong wind. you apply a constant force \vec{f} =(33 n)\hat{i} - (41 n)\hat{j} to the cart as it undergoes a displacement \vec{s} = (-9.4 m)\hat{i} - (3.1 m)\hat{j}.
part a
how much work does the force you apply do on the grocery cart?
express your answer using two significant figures.

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?
