Explanation:
If a large photon strikes the surface, that has enough strength to take out an electrode, which will then travel to the positive side since it is negative. Current is flowing at this stage. Since the reduced photons will be unable to distinguish between atoms, no power can pass.
Question:
At standard temperature and pressure, the volume of a tire is 3.5L. What is the new pressure if the temperature outside is 296k and its weight causes the volume of the gas is 2.0 L?
Answer:
The new pressure is: 1.896 atm
Explanation:
At standard temperature and pressure, we have:
Outside, we have:
Required
Determine the new pressure
Using combined gas law, we have:
This gives:

The relative atomic mass of element X is 41.4 amu while the relative atomic mass of the second element is 162.3 amu
The questions are incomplete, the complete questions are;
1) Element X has three naturally occurring isotopes. The mass (amu) and % abundance of the isotopes are 37.919 amu (5.07%), 39.017 amu (15.35%), and 42.111 amu (79.58%). What is the average atomic mass of element X?
2) A certain element has three isotopes. The isotopic masses and abundances are: 159.37 amu (30.60%), 162.79 amu (15.79%), and 163.92 amu (53.61%). What is the average atomic weight of the element?
We can obtain the average atomic mass the the sum of the products of relative abundance and isotope mass for all the isotopes of the element.
Note that isotopes of an element has different masses and abundances. The average atomic mass of the element includes contribution from all these isotopes.
1) (37.919 × 0.0507) + (39.017 × 0 .1535) + (42.11 × 0.7958) = 41.4 amu
2) (159.37 × 0.3060) + (162.79 × 0.1579) + (163.92 ×0 .5361) = 162.3 amu

Answer:
Density = mass/ volume
Explanation:
57.4g / 11.5cm3 = 4.991304(g/cm)
round to sig figs = 5.00(g/cm)
