Answer:
Atoms consist of nucleus made by protons and neutrons orbited by electrons.
Explanation:
Answer:
Part A - The combined angular momentum of the masses is 0.48 kg-m^2/s.
Part B - 0.0495 is her linear speed.
Explanation:
Part A - We know that angular momentum is the measure of the amount of rotation of the body and is the product of of the moment inertia and the angular velocity. The equation for the moment of inertia can be expressed as l=mr^2 in which m is the mass and r is the radius of the circle. According to the problem, r is 0.6m. Then, l=2kg*(0.6)^2=0.72kg-m2/s2. We also know that angular velocity is the product of linear velocity and the radius which can be expressed as w=rv. Therefore, w=0.6*11 which equals to 0.66 rad/s. The angular momentum is 0.72 kg-ms/s2*0.66 rad/s. Which equals to 0.48 kg-m^2/s.
Part B - First we use l=mr^2, where m=2 kg and r=0.15m. 0.15 becomes 0.225 and when multiplied with 2 is 0.045, giving us the moment of inertia to plug in the following equation. L=l*w where l is 0.045 and w is 1.1 m/s. 1.1 times 0.045 is 0.0495 which is in other words, her linear speed.
I am rusty with this, but I hope it helps!
Answer: Here are the complete options.
A spontaneous process is one that occurs very quickly. A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium. A spontaneous process is one that occurs without continuous input of energy from outside the system. A process is spontaneous if it must be continuously forced or driven.
The correct option is
A spontaneous process is one that occurs without continuous input of energy from outside the system.
A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium
Explanation:
spontaneous process is one that occurs without continuous input of energy from outside the system and occur on its own because spontaneous processes are thermodynamically favorable characterized by a decrease in the system's free energy, they do not need to be driven by an outside source of energy. Which means that the initial energy is higher than the final energy.
A process that is spontaneous in one direction is nonspontaneous in the other direction under a given set of conditions, provided the system is not at equilibrium which will result to The sign of ΔG will change from positive to negative (or vice versa) where T = ΔH/ΔS. In cases where ΔG is: negative
