Answer:
change in mass = 2.41*10^{8}kg
Explanation:
The change in the mass can be computed by using the relation
(1)
That is, the energy liberated comes from the mass of the nuclear fuel. The energy generated in one year is
Hence, by replacing in the equation (1) you have (c=3*10^{8}m/s)
HOPE THIS HELPS!!
Oxygen and Neon have the same number of valence electrons because both the compounds are in the same group and the outer orbital of both the compounds consists of 6 electrons
Answer:
i think its because u gave the almost every answer the same exact thing. all the questions have different ways of moving which means different forces for each one i hope this helps :)
Explanation:
Answer:
Explanation:
There is electric field between the plates whose value is given by the following expression
electric field E = V /d where V is potential between the plates and d is distance between them
E = 300 / 5 x 10⁻³
= 60 x 10³ N/c
Force on electron = q E where q is charge on the electron
F = 1.6 X 10⁻¹⁹ X 60 X 10³ = 96 X 10⁻¹⁶ N.
Acceleration a = force / mass
a = 96 x 10⁻¹⁶/ mass = 96 x 10⁻¹⁶ / 9.1 x 10⁻³¹
= 10.55 x 10¹⁵ m / s²
For midway , distance travelled
s = 2.5 x 10⁻³ m
s = 1\2 a t²
t = 
= 
t = .474 x 10⁻¹⁸ s
For striking the plate time is calculated as follows
t = ![[tex]\sqrt{\frac{2\times5\times10^{-3}}{ 10.55\times10^{15}}](https://tex.z-dn.net/?f=%5Btex%5D%5Csqrt%7B%5Cfrac%7B2%5Ctimes5%5Ctimes10%5E%7B-3%7D%7D%7B%2010.55%5Ctimes10%5E%7B15%7D%7D)
[/tex]
t = 0.67 x 10⁻¹⁸ s
Answer:
C. water is more dense and viscous
Explanation:
Rapid gas exchange can be accomplished more easily in air than in water because water is more dense and viscous.
Gases have the greatest ease of diffusion of their respective particles, as occurs in air, since their molecules have higher speeds and have more distance from each other than liquids.
The molecular diffusion rate in liquids is much less than in gases. The molecules of a liquid are very close (liquids are more dense and viscous) to each other compared to those of a gas, then the gas molecules hits with the molecules of the liquid with more frequency and this causes that the gas moves slower than in other gas (for example in air).
