Three particles a, b, and c enter a magnetic field as shown below. What can you say about the charge on each particle (symbol O with x in the middle represents magnetic field pointing into the page)?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

Need only answer if you think you know it
