Consider a weight suspended from a string wrapped around the hub of a flywheel. When the weight is released, the flywheel and hub rotate together about the fixed axis O. If the hanging weight is 30.0 N, the radius of the hub(r)is 20.0 cm, and the moment of inertia of the flywheel is 24 kgm2, calculate the torque and angular acceleration of the flywheel.

moving ball hits still ball. mover stops, hit ball moves. momentum transfer.

i believe it is b. what was the cause of the big bang

hope this !

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
