Answer:
Addition of shells increases the distance of outer electrons from the nucleus.
Explanation:
Shielding effect is known as the attraction between the nucleus and an electron of any atom. In other words, it is the reduction in effective nuclear charge on an electron cloud.
Addition of electron shells results in the shielding of electron from nucleus. As the number of electron shells increases then farther will be the electrons placed from the nucleus and hence it will become easier to expel the electrons from outer shells with only little amount of ionization energy.
So, the amount of ionization energy require will be indirectly proportional to the shielding effect because more the shielding of electrons from the nucleus less will be the ionization energy require to expel the electrons.
Answer:
With a vector, however, the sign simply tells you about the direction of the vector. If you're travelling with a velocity of 20 km/hr east, it means you're travelling east, and your speed is 20 km/hr.
To develop this problem it is necessary to use the expression that allows us to convert the degrees Celsius to Fahrenheit. The expression that allows to realize it is given mathematically by:
In this way for 33.2 °C:
In this way for 38.2°C
Expressed in a range term, we can say that the measure in degrees Fahrenheit is:
![[91.76\° F , 100.76\° F]](https://tex.z-dn.net/?f=%5B91.76%5C%C2%B0%20F%20%2C%20100.76%5C%C2%B0%20F%5D)
Explanation:
The initial kinetic energy 
for both blocks is zero. Let 
and 
. So using the conservation law of linear momentum, we can write
or
The final kinetic energies for the two masses are
Therefore, the ratio of their kinetic energies is
Kinetic energy=0.5*mass*(velocity^2)
15,000 J=0.5*50*v^2
15,000J=25v^2
600 J=v^2
Velocity= 24.49 ms^-1
