I hope my answer helped you. have a nice day!
Answer: 2000cm3
Explanation:
Given that,
Initial volume of gas V1 = 1000cm3
Initial temperature of gas T1 = 300K
New volume V2 = ?
New Temperature T2 = 600 K
Since volume and temperature are involved while pressure is constant, apply the formula for Charles law
V1/T1 = V2/T2
1000cm3/300K = V2/600K
3.33 = V2/600
To get the value of Z, cross multiply
V2 = 3.33 x 600
V2 = 2000cm3
Thus, the new volume of the ideal gas is 2000cm3
Answer:
45,300 N
Explanation:
The significant figures are the digits that cannot be eliminated from the number without changing its value. Let's analyze each case:
450.3 N --> this number has 4 significant figures: 4, 5, 0, 3
0.04503 N --> this number has 6 significant figures: 0, 0, 4, 5, 0, 3
45,300 N --> this number has 5 significant figures: 4, 5, 3, 0, 0
4.5300 N --> this number has 3 significant figures: 4, 5, 3 (the two final zeroes can be removed from the number without changing its value)
The moment of inertia for rotation about a perpendicular axis through its center is 1.3 × 10⁻⁶ gm².
<h3>Moment of Inertia:</h3>
The measurement of a body's rotational inertia is its moment of inertia. The body's resistance to a change in the speed at which it rotates along an axis as a result of an applied torque (turning force) operating on the body.
For a disc, the moment of inertia about the perpendicular axis through the center is given by 0.5MR².
Where,
M is the mass of the disc
R is the radius of the disc.
For the axis through the edge, use the parallel axis theorem.
I = I(axis through the center of mass) + M(distance between the axes)²
= 0.5MR² + MR² (since the axis through the center of mass is the axis
through the center).
= 1.5 MR²
I = 1.5 × 21 × (13/2)²
= 1330.875 gm²
= 1.3 × 10⁻⁶ gm²
Therefore, the moment of inertia for rotation is 1.3 × 10⁻⁶ gm².
