Answer:
The correct answer is Option A (decrease).
Explanation:
- According to Heisenberg's presumption of unpredictability, it's impossible to ascertain a quantum state viewpoint as well as momentum throughout tandem.
- Also, unless we have accurate estimations throughout the situation, we will have a decreased consistency throughout the velocity as well as vice versa though too.
Other given choices are not connected to the given query. Thus the above is the right answer.
The answer is :78 I think
-- Toss a rock straight up. The kinetic energy you give it
with your hand becomes potential energy as it rises.
Eventually, when its kinetic energy is completely changed
to potential energy, it stops rising.
-- When you're riding your bike and going really fast, you come
to the bottom of a hill. You stop pedaling, and coast up the hill.
As your kinetic energy changes to potential energy, you coast
slower and slower. Eventually, your energy is all potential, and
you stop coasting.
-- A little kid on a swing at the park. The swing is going really fast
at the bottom of the arc, and then it starts rising. As it rises, the
kinetic energy changes into potential energy, more and more as it
swings higher and higher. Eventually it reaches a point where its
energy is all potential; then it stops rising, and begins falling again.
The choices above are social psychology terms
that help describe the people’s actions in their everyday interaction with
people. The sentence example is:
Those computer geeks are all the same.
They
spend all day playing video games and programming their computers to serve them
breakfast. I don't think I've ever seen one reading a real book or throwing a
baseball. Why, they're almost like machines!

Is an example of stereotyping. Stereotyping
happens when a person applies a single group behavior or minority behavior to a
whole group ‘s behavior sharing the same characteristic.</span>
Answer:
Wnet, in, = 133.33J
Explanation:
Given that
Pump heat QH = 1000J
Warm temperature TH= 300K
Cold temperature TL= 260K
Since the heat pump is completely reversible, the combination of coefficient of performance expression is given as,
From first law of thermodynamics,
COP(HP, rev) = 1/(1-TL/TH)
COP(HP, rev) = 1/(1-260/300)
COP(HP, rev) = 1/(1-0.867)
COP(HP, rev) = 1/0.133
COP(HP, rev) = 7.5
The power required to drive the the heat pump is given as
Wnet, in= QH/COP(HP, rev)
Wnet, in = 1000/7.5
Wnet, in = 133.333J. QED
So the 133.33J was the amount heat that was originally work consumed in the transfer.
Extra....
According to the first law, the rate at which heat is removed from the low temperature reservoir is given as
QL=QH-Wnet, in
QL=1000-133.333
QL=866.67J
