An engineer uses aluminum to build an airplane rather than composite materials that are lighter and stronger. He does this because he is concerned about the composite materials and how suddenly they can fail. This is an example of:

Teresa wanted to test the effects of liquid density on the speed of sound waves. what is the dependent variable in her experiment?

A proton (mass = 1.67*10-27 kg, charge = 1.6*10-19 C) travelling with speed 1*106 m/s enters a region of space containing a uniform magnetic field of 1.2 T. What is the time t required for the proton to re-emerge into the field-free region? t =
