M = 2.2 g = 2.2 x 10⁻³ kg, the mass of the bug.
r = 3.0 cm = 0.03 m, the radial distance from the center.
The angular speed is
ω = 280 rpm
= (280 rev/min)*(2π rad/rev)*(1/60 min/s)
= 29.3215 rad/s
The moment of inertia of the bug is
I = mr²
= (2.2 x 10⁻³ kg)*(0.03 m)²
= 1.98 x 10⁻⁶ kg-m²
Calculate the angular momentum of the bug.
J = Iω
= (1.98 x 10⁻⁶ kg-m²)*(29.3215 rad/s)
= 5.806 x 10⁻⁵ (kg-m²)/s
Answer: 5.806 x 10⁻⁵ (kg-m²)/s
The mass of the object doesn't matter. The change in its momentum is equal to the impulse that changed it ... 15 N-sec.
What I found was from another website and it said "For most of the year, Atlantic puffins live on the open ocean, with a range spanning from the eastern coast of Canada and the northern United States to the western coast of Europe and northern Russia. 60% of the world's puffins live near Iceland. Puffins are specially adapted to living<span> on the open sea." here is the link https://animalfactguide.com/animal-facts/atlantic-puffin/
I put the link and a picture so it hopefully won't be deleted for plagiarism.

Answer:
Q = 73325 J or 73.325 KJ
Explanation:
Given the following data;
Specific heat capacity of water = 4190
Mass = 0.5kg
dt = 65 - 30 = 35°C
Heat capacity is given by the formula;
Q = mcdt
Where,
Q represents the heat capacity.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
Substituting into the equation, we have:
Q = 0.5 * 4190 * 35
Q = 73325 Joules.
