Answer:
The speed of nitrogen molecule is 1.87 m/s.
Explanation:
Given that,
Pressure = 2 atm
Density = 1.7 grams/liter
Atomic weight = 28 grams
We need to calculate the temperature
Using formula of idea gas
Put the value into the formula
We need to calculate the speed of nitrogen molecule
Using formula of RMS speed
Hence, The speed of nitrogen molecule is 1.87 m/s.
Answer:
10.09 N
Explanation:
Analogously to Newton's second law, torque can be defined as:
Here, I is the moment of inertia and is the angular acceleration. We have:
Torque is the vector product of the position vector of the point at which the force is applied by the force vector:
Since the effective lever arm is perpendicular to the force, the angle between them is . The magnitud of this vector product is defined as:
.
Solving for F and replacing the known values:
