A 100.00 ml of volume of 0.500 m hcl was mixed with 100.00 ml of 0.500 m koh in a constant pressure calorimeter. The initial temperature of individual acid and base was 23.0 oc. The final temperature after mixing was 25.5 oc. The specific heat of the solution was 3.97 j g-1 oc-1 assume the density of the solution is 1.00 g ml-1

a, c, d, e are all applying about success strategies.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

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
