The kelvin temperature of an object is t1 and the object radiates a certain amount of energy per second. the kelvin temperature of the object is then increased to t2, and the object radiates 53 times as much energy per second as it radiated at the lower temperature. what is the ratio t2/t1?

What is special about a dc circuit ?

Which of the following changes will increase the capacitance of a parallel-plate capacitor? (there could be more than one correct choice.) a) increase the charge on the plates b) decrease the poten5al between the plates c) increase the potential between the plates d) introduce a dielectric material between the plates e) decrease the separation between the plates

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
