Answer:

Why the gravitational force is greater near the poles and less at equator?

Gravitational force of Earth is minimum at equator because the centrifugal force at the equator is maximum.

Centrifugal force is an outward force exerted on a body revolving in a circular path, to mantain its state of motion.

Explanation:

Here Earth revolves around its axis and the same forces act on it to enable its revolution.

Gravitational force at the equator is less because Centrifugal force, which is also acting at the equator cancels out the Gravitational force to an extent. Whereas at poles, there is no such effect of centrifugal force because earth is sphere (bulged at center; flat at poles )and hence gravitational force is maximum at poles.

The other reason is distance from any place on equator to centre of earth is more than at poles. Because Earth is bulged at centre and flat at poles. Since Gravitational force is given by

F= GMm/ r^2 ; r is the distance between two bodies.

What is the wavelength of gamma ray electromagnetic radiation with a frequency of 2.73x10^20 Hz?

Amanda [17]

Answer:

1.10 × 10⁻¹² m

General Formulas and Concepts:

Chemistry - Atomic Structure

Speed of Light = Wavelength times Frequency

c = λν
c = 3.0 × 10⁸ m/s

Explanation:

Step 1: Define

ν = 2.73 × 10²⁰ Hz

Step 2: Find wavelength

3.0 × 10⁸ m/s = λ(2.73 × 10²⁰ Hz)

λ = 1.0989 × 10⁻¹² m

Step 3: Check

We are given 3 sig figs. Follow sig fig rules.

1.0989 × 10⁻¹² m ≈ 1.10 × 10⁻¹² m

An alternative definition of electronegativity is Electronegativity= constant (I.E — E.A.) where I.E. is the ionization energy a

Kazeer [188]

Answer:

The electronengativity values of given elements is as follows.

Fluorine - 4

Chlorine -3

Bromine - 2.9

Iodine- 2.5

Explanation:

Electronegativity =consant (I.E-E.A)

The electron affinity and ionization energy values of the given elements is as follows.

(In attachment)

First we have to find the value of constant by using the fluorine atom to whom the electronengativity taken as "4".

Fluorine:

$4=constant[1678-(-327.8)]$

$Constant=0.0019942168$

By using this constant values we can find electronegatvity values of remaining elements.

Chlorine:

$Electronegativity=0.0019942168[1255+348.7]=3.1980\sim 3$

Therefore, electronegativity of chlorine is 3.

Bromine:

$Electronegativity=0.0019942168[1138+324.5]=2.91\sim 2.9$

Therefore, electronegativity of bromine is 2.9.

Iodine:

$Electronegativity=0.0019942168[1007+295.7]=2.59\sim 2.5$

Therefore, electronegativity of iodine is 2.5.
