Answer:
C)Thirty percent
Explanation:
This question is about the article "Fad, fashion or classic? How to shop sensibly." Where the narrator states that a person's wardrobe must be in accordance with his daily life and the number of activities he does. In this article, Michael Kors states that a person's wardrobe must consist of 70% comfortable clothes and 30% fad clothes, however, this percentage must be adapted to the daily life of each person, always prioritizing the activities he does and the places who attends.
Answer:
x = 70°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an external angle of the triangle, thus
x + 50 = 120 ( subtract 50 from both sides )
x = 70
Answer:
2440.24 J
Explanation:
Moment of inertia, I1 = 5 kg m^2
frequency, f1 = 3 rps
ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s
Moment of inertia, I2 = 2 kg m^2
Let the new frequency is f2.
ω2 = 2 x π x f2
here no external torque is applied, so the angular momentum remains constant.
I1 x ω1 = I2 x ω2
5 x 6 π = 2 x 2 x π x f2
f2 = 7.5 rps
ω2 = 2 x π x 7.5 = 15 π
Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J
Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J
Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J
Ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.
Ionic charge is the electrical charge of an ion formed when when an atom gains or losses electron.
Metals form ionic charge (cation) by the loss of electron while non-metal form ionic charge (anion) by the gain of electron.
- This ionic charge increases across the group and consequently, results in a decrease of ionic radius.
- When a positive ion (cation) transfers electron to the negative ion (anion) an Ionic bond will be formed.
<u>For example</u>;
- ionic charge of group 1 elements = +1
- ionic charge of group 2 elements = + 2
- ionic charge of group 3 elements = + 3
- ionic charge of group 4 elements (carbon group) = -4 or +4, (<em>they don't usually form ions</em>)
- ionic charge of group 5 elements = -5
- ionic charge of group 6 elements = -6
- ionic charge of group 7 elements = -7
Thus, we can conclude that ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.
