The Answer is A
Hope this helped ;)
Explanation:
The kinetic energy of translation
m= mass v= linear velocity
The kinetic energy of rotation
I= MOI of the thin walled sphere =kmR^2
where ω= v/R= angular velocity
Then
=1/k
solid sphere: k=0.4; E1/E2 =1/0.4 = 2.5;
hollow sphere: k=2/3; E1/E2 = 1.5
Answer:
λ = 4.59 ×10⁻³ nm
Explanation:
Given data:
Energy of light = 4.33 ×10⁻¹⁴ J
Wavelength of light = ?
h = 6.626×10⁻³⁴ js
c = 3×10⁸ m/s
Solution:
Formula:
E = hc/λ
4.33 ×10⁻¹⁴ J = 6.626×10⁻³⁴ Js× 3×10⁸ m/s / λ
λ = 6.626×10⁻³⁴ Js× 3×10⁸ m/s / 4.33 ×10⁻¹⁴ J
λ = 19.878 ×10⁻²⁶ Jm / 4.33 ×10⁻¹⁴ J
λ = 4.59 ×10⁻¹² m
λ = 4.59 ×10⁻³ nm
Answer: you are the imposter you killed red then vented in admin
Explanation:
Answer is: A) The solution turns blue litmus to red.
Sulfuric acid (H₂SO₄) is a strong acid, it means that the solution of sufuric acid is more acidic (pH<7) than water (pH = 7).
Chemical dissociation of sulfuric acid in water:
H₂SO₄(aq) → 2H⁺(aq) + SO₄²⁻(aq).
When solution turns phenolphthalein pink, it means it is basic (pH>7).
Sulfuric acid has more hydrogen ions (H⁺) and less hydroxide ions (OH⁻) than water.
