a. deflate because volume is directly proportional to temperature

b. deflate because volume is inversely proportional to temperature

c. expand because volume is inversely proportional to temperature

d. stay the same size because there is no relationship between volume and temperature

Which transition by an electron will release the greatest amount of energy? oa ob oc od

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction
