Amassless rod of length l has a small mass m fastened at its center and another mass m fastened at one end. on the opposite end from the mass m, the rod is hinged with a frictionless hinge. the rod is released from rest from an initial horizontal position; then it swings down. what is the angular velocity as the rod swings through its lowest (vertical) position?

coil wire, increase current, put iron inside the coil

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

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
