Calculate the numerical value of fb in n. no attempt no attempt 13% part (e) express the total force f in terms of w and fb assuming upward is the positive direction. no attempt no attempt 13% part (f) calculate the numerical value of f in n. no attempt no attempt 13% part (g) express the acceleration a in terms of f, rhob and vb. no attempt no attempt 13% part (h) calculate the numerical value of a in m/s2.

need to see circuit to get time constant

what is the actual question though?

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

moisture is lackin, and organic acids are scarce.
