Iron has a known density of 7.9g/ml. if a sample of iron has a mass of 84.5 grams, how many millimeters of water will the sample displace?

10.6962 ml

Explanation:

the density of water is 1g/ml

if you devide the mass by density you get the volume the volume times density is equal to the mass so

84.5 grams devided by 7.9 is equal to 10.6962 ml.

if you do that times 1g/ml is equal to 10.6962 g/ml.

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

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
