<span>when the temperature of an ideal gas remains constant, the product of the pressure and volume of the gas is constant. Therefore, the volume the gas is inversely related to its pressure. </span>
(a) The moment of inertia of the sign for rotation about the side of length h is 1.24 kgm².
(b) The kinetic energy of the sign when it is rotating about an axis is 141.37 J.
<h3>Moment of inertia of the triangular sign</h3>
The moment of inertia of the sign for rotation about the side of length h is calculated as follows;
I = 2 x ¹/₃M(b/2)²
I = 2 x ¹/₃Mb² x ¹/₄
I = ¹/₆Mb²
I = ¹/₆ x 4.4 x 1.3²
I = 1.24 kgm²
<h3>Rotational kinetic energy of the ball</h3>
K.E(rot) = ¹/₂Iω²
where;
- ω is angular speed = 2.4 rev/s = 2.4 x (2π rad)/s = 15.1 rad/s
K.E(rot) = ¹/₂(1.24)(15.1)²
K.E(rot) = 141.37 J

To find the average (aka mean) of a group of numbers, all we need to do is add them up then divide that number by how many numbers we started with
23 + 21 + 24 + 22 = 90
90 ÷ 4 = 22.5
Therefore, the average distance the book traveled on ice is 22.5 cm
15 + 18 + 16 + 17 = 66
66 ÷ 4 = 16.5
Therefore, the average distance the book traveled on concrete is 16.5 cm
In conclusion, the average distance the book traveled on ice is greater than the average distance the book traveled on concrete

1 BTU mean 1 degree of F increased for 1 pound mass. Since the mass unit is in kg that means you need to convert it into pound. One metric ton means 1000kg and 1 kg mean 2.20462lb, then the water mass is: 1000kg x 2.20462lb/kg= 2204.62lb.
You are putting 110,000 btus of heat, so the calculation would be
Temperature increase= energy/mass = 110000btus/ 2204.62lb= 49.9 degree
