Explanation:
Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.
While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.
As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.
Frequency = speed ÷ wavelength
= 330m/s ÷ 2.5m
= 132 Hz
The soft underbelly of the axis is referred to as Italy. Hope this helps!
Answer: 79.0 x 10²³ kg
Explanation:
The weight of any mass, is given by the value of the attractive force that the mass of the planet exerts on it, and is given by the Newton's Universal Law of Gravitation:
Fg = G m Mp / rp²
If Fg = 25.74 N, we can solve for Mp, as follows:
Mp = Fg . rp² / G m = 25.74 N. (7.3 10⁶)² m² / 6.67259. 10⁻¹¹ N.m²/ kg². 2.6 kg
Mp= 79.0 x 10²³ kg.
