Suppose that the emf from a rod moving in a magnetic field was used to supply the current to illuminate a light bulb in a circuit, and the force needed to keep the rod moving is . What happens to the force needed drive the motion of the rod if the light bulb is removed?a. No force is neededb. there is no longer a magnetic force to oppose the motion. c. It is the same as when the bulb is in the circuit. d. A larger force is needed to the keep the rod moving

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3

The pressure on how fast or slow the car is going

Ais the answer as neutral object contain both charges so thats why they can be attracted
