Stephen is worried he has a fever. His dad is a scientist though and only has thermometer that measures in kelvin and is measured stephen’s temperature to be 312 kelvin. If stephens temperature is above 100 f he isn’t allowed to go to school. Can Stephen go to school today?

the answer for apex is the lowest

because growing process had stoped after 4-5 year

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
