Answer:
3.5434 eV
Explanation:
For a particle with kinetic energy E and mass m , the wavelength associated is given by the following relation,
E = 
Putting the values we get
E = 
=1.063 x 10⁻²¹ J
= .0066 eV.
Energy of¹light in terms of eV
= 1244 / 350 = 3.55 eV.
Work function = 3.55 - 0.0066 = 3.5434 eV.
Answer:
Gravitational potential energy is due to the position of an object above Earth's surface. The object has the potential to fall due to gravity.
Explanation:
Gravitational potential energy depends on an object's weight and its height above the ground (GPE = weight x height). hope this helps you :)
Answer:
(a) 1/60
(b) Yes, it was unusual.
Explanation:
Number that went to the right field = 19
Number that went to the right center field = 18
Number that went to the center field = 12
Number that went to the left center field = 10
Number that went to the left field = 1
Total number of home runs = 60
(a) The probability that a randomly selected home run was hit to left field is
P(left field) = 1/60
(b) It was unusual because whenever a player hit a home run, it most times went to the right field,which is why the right field had the highest probability, 19/60.
On the other hand, it went to the left field the least number of times, which is why the left field had the least probability, 1/60.
So, it was unusual.
