Answer:
266.7k
Explanation:
Given parameters:
Initial pressure = 36Pa
Initial temperature = 300k
New pressure = 32Pa
Unknown:
New temperature = ?
Solution:
To solve this problem, we have to apply the combined gas law when the volume is constant;
in this instant, when the volume is constant, the pressure of a given mass of gas varies directly with the absolute temperature.
=
P and T are pressure and temperature
1 and 2 are initial and final states
Insert the parameters and solve;
=
T₂ = 266.7k
Answer: A.) v = 2πr/T
Explanation:
The tangential speed of an orbiting object can be obtained by the product of the radius of the orbit and the angular speed of the object in a circular motion.
This the tangential seed can be represented mathematically as :
Tangential speed (v) = angular speed(ω) × radius(r)
v = r × ω --------(1)
Recall:
ω = 2π/T
Substituting ω = 2π/T in equation (1)
v = r × 2π/T
v = 2πr/T
