The force of gravity is less between to objects when the product
of their masses is smaller, or when they are farther apart.
Answer:
Explanation:
Initial volume v₁ =46 x 10⁻⁶ m³
Initial temperature T₁ = 438.28 + 273 = 711.28 K
Initial pressure P₁ = nRT₁ / v₁
= 30.4 x8.3 x 711.28 / (46 x 10⁻⁶ )
= 3901.5 x 10⁶ Pa
Final temperature T₂ = 824 + 273 = 1097 K
Final volume V₂ =?
For isobaric process
v₁ / T₁ = V₂ / T₂
V₂ = V₁ X T₂ /T₁
= 46 X 10⁻⁶ X 1097/ 711.28
= 70.94 X 10⁻⁶ m³ = 70.94 cm³
b ) For isothermal change
P₁ V₁ = P₂V₂
P₂ = P₁V₁ / V₂
= 3901.5 X 10⁶ X 46 / 24.3
7385.55 X 10⁶ Pa.
Answer:
Δω = -6.00 rad/s
α = -2.61 m/s²
Explanation:
Step 1: Data given
A bicycle tire is spinning counterclockwise at 3.00 rad/s
Δt = 2.30 s
In theopposite (clockwise) direction, also at 3.00 rad/s
Step 2: Calculate the change in the tire's angular velocity Δω
Δω = ωf - ωi
ωf = - 3.00 rad/s
ωi = 3.00 rad/s
Δω = ωf - ωi = -3.00 - 3.00 = -6.00 rad/s
Step 3: Calculate the tire's average angular acceleration α
α = Δω / ΔT
α = -6.00 rad/s /2.30s
α = -2.61 m/s²
A negative angular acceleration means a decreasing angular velocity
