    Centripetal force on a turning bus

    Isn't the bus going too fast so centripetal force that allows it to turn right is larger, hence providing a torque that will tip the bus over to the right (i.e. clockwise torque)?

    Centripetal force on a turning bus

    Homework Statement Consider the rear view of a bus turning right. If the driver turned the bus while traveling too fast, the bus could topple over. If the bus did topple would the bus fall to the left or to the right? Explain. Since the bus was turning to the right, the centripetal force...

    What is the difference in spectra between a sodium lamp and a candle flame?

    Homework Statement Hi, I'm having a bit of trouble explaining this physics phenomenon: A sodium lamp emits yellow light; that to the human eye appears to be quite similar to a candle flame in colour. When light from these two sources is viewed through a spectroscope, it is found that...

    What is the equilibrium force on a weight down a slope?

    Sorry, I'm still a bit confused... The 5 kg weight is on a 30˚ slope and the spring scale is on the slope as well. How am I supposed to work out a horizontal force? Is that the force that will be recorded by the spring scale? Thank you!

    How Does Changing Wire Resistance Affect EMF in an AC Generator?

    Homework Statement This is the solution to one of the problems I came across: In an AC generator, a coil spins in a magnetic field. Of the following choices, circle the one that will not cause an increase in the EMF generated in the coil? a. replacing the coil wire with one of lower...

    What is the equilibrium force on a weight down a slope?

    Homework Statement I have attached a picture of the problem to this thread, I am having trouble with part c. I am getting an answer which is much larger than 24.5N The systems shown in the figures are in equilibrium. If the spring scales are calibrated in Newtons, what do they read? (assume...
