How do you say 0.80?
"zero point eight zero"
What does is mean when a system has reached equilibrium?
if there is no motion of a lever around a fulcrum, then how do the torques compare? the torques must be equal. this does not necessarily imply that the forces or the lever arms involved are equal. when this situation occurs we say the lever system is in equilibrium.
Can potential energy ever be less than kinetic energy?
The answer to both of your questions lies in the different nature of both quantities, momentum and kinetic energy. Momentum is a vector, kinetic energy is a scalar. This means that momentum has a magnitude and a direction, while kinetic energy just has a magnitude. Consider the following system: 2 balls with equal mass are rolling with the same speed to each other. Magnitude of their velocities is the same, but the directions of their velocities are opposed. What can we say about the total momentum of this system of two balls? The total momentum is the sum of the momentum of each ball. Since masses are equal, magnitudes of velocities are equal, but direction of motion is opposed, the total momentum of the system of two balls equals zero. Conclusion: the system has zero momentum. What can we say about the total kinetic energy of this system? Since the kinetic energy does not take into account the direction of the motion, and since both balls are moving, the kinetic energy of the system will be different from zero and equals to the scalar sum of the kinetic energies of both balls. Conclusion: we have a system with zero momentum, but non-zero kinetic energy. Assume now that we lower the magnitude of the velocity of one of the balls, but keep the direction of motion. The result is that we lower the total kinetic energy of the system, since one of the balls has less kinetic energy than before. When we look to the total momentum of the new system, we observe that the system has gained netto momentum. The momentum of the first ball does not longer neutralize the momentum of the second ball, since the magnitudes of both velocities are not longer equal. Conclusion: the second system has less kinetic energy than the first, but has more momentum. If we go back from system 2 to system 1 we have an example of having more kinetic energy, but less momentum. I hope this answers your question Kjell
Can an object have a non zero force and have constant kinetic energy?
an object can have a non zero force acting upon it if and only if the sum of all of the forces on the object is still equal to zero. The sum of the forces is equal to mass times acceleration. If an object is accelerating, then it does not have a constant KE therefore the sum of the forces must be equal to 0 so that acceleration is also equal to zero. For instance, take the case of an object falling through the air. Initially, the force of gravity is accelerating the object downward and it is gaining KE. After some time, this object will reach terminal velocity. At this point, the resistance force of the air on the object negates the force of gravity and the sum of the forces is equal to zero. The object now falls at a constant velocity and in turn also a constant KE. It is still being acted upon by the force of gravity and the resistance force but these forces are canceling each other out. =============================== I don't like to delete an answer that somebody put a lot of effort into, and supervisors don't like it when I become plainly uncomplimentary. So all I can say is: Use the above answer at your own extreme peril, and far better to ignore it. Especially the 1st and 3rd sentences.
Which description applies to a system in a sealed flask that is half full of water?
The system in the sealed flask that is half full of water can be described as a closed system since nothing can enter or leave the flask. Additionally, it can be regarded as an equilibrium system since the water level remains constant and there is no net change in the system.
What does it mean to say a system delta g has an equal to zero?
When ΔG is zero, the process is already in equilibrium, with no net change taking place over time
What can you say about the sum of a number and its opposite?
They equal zero.
How do you say 43.1002?
Expressed in words, this is equal to forty-three point one zero zero two.
How do you say 0.0517 in word form?
Expressed in words, this is equal to zero point zero five one seven.
Why does one to the power of zero equal zero?
Any number to the power zero equals 1. A possible exception is zero to the power zero. Some people claim it is equal to zero, others say it equals one, consistent with any other value. Still more say that the result of zero to the power zero is an undefined value. With the possible exception of zero, the statement above holds true for any value.
How do you say 6 00 in spanish?
If you mean 'six o'clock' - las seis If you mean six zero zero - seis zero zero If you mean 600 - seiscientos
What does mil mean in soccer They say 1 mil in the half I know its zero But why do they say that?
It's actually nil and it means zero.
What is 0 comma 0 mean?
In some countries, people say zero comma zero instead of zero point zero. In short, it means zero, with 1/10 precision.
How do you say the number 0.7542?
Expressed in words, this is equal to zero point seven five four two.
What happens if an object covers equal distances in equal periods of time?
Then you can say that the object's speed and the magnitude of its velocity are constant, and the magnitude of its acceleration is zero.
What does it mean when people say you divided by zero?
It means that your not making any sense? Cause you can't divide a number by zero.
How do you say 9.806415?
Expressed in words, this is equal to nine point eight zero six four one five.
