In a car factory, there are 8.0 assembly lines. Each assembly lines manufactures cars at the same speed. There are 12 workers working on each assembly line. How many employees are there in total? How many sig figs should your answer be in? Rounding to proper sig figs.
Remember when multiplying or dividing to round to the least number of sig figs.
A.1
B.2
C.3
d. none of the above

i think the answer is a, hope this is right, that would be my best guess.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
