Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
<span>a) Work = force x distance = 5.0 x 10^5 x 509 = 2.54 x 10^8
b) no change in velocity, therefore KE = 0
c) KE = 31 J
d) v = 15 m/s</span>
Explanation:
The de broglie wavelength is given by :
Here,
h is Planck's constant
p is momentum
Momentum and De-Broglie wavelength has inverse relationship. If momentum of an electron double, its wavelength gets half.
Explanation:
Since the current flowing through an ideal capacitor is described by equation:
for voltage across the capacitor constant with time the current is:
Open switch has this characteristics (Constant voltage and zero current).
