Technician a says a lab scope can be used to measure resistance. technician b says that a lab scope can be used to measure frequency by dividing the length of a cycle into 1. who is correct?

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

pecialized keyboards

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
