Answer:
Increases the input force and decreases the input distance
Explanation:
When a force is applied over a given distance, there is an inverse relationship between the applied force and distance. Example is a tommy bar, when the length increases the force required decreases. This principle is applied to this wrench.

The kinetic energy of the alpha particles heats the air.
The alpha particle is so energetic that it leaves a smoke trail behind.
The alpha particle strikes nitrogen molecules and breaks them into atomic nitrogen.
Answers
Answer: Ionization by the alpha particle seeds the formation of clouds where the particle has passed.
The inner atmosphere of a cloud chamber is composed of an easily ionizable gas, this means that little energy is required to extract an electron from an atom. This gas is maintained in the supercooling state, so that a minimum disturbance is enough to condense it in the same way as the water is frozen.
Then, when a charged particle with enough energy interacts with this gas, it ionizes it.
This is how alpha particles are able to ionize some atoms of the gas contained inside the chamber when they cross the cloud chamber.
These ionized atoms increase the surface tension of the gas around it allowing it to immediately congregate and condense, making it easily distinguishable inside the chamber like a small cloud. In this way, it is perfectly observable the path the individual particles have traveled, simply by observing the cloud traces left in the condensed gas.

Answer:
+16 J
Explanation:
We can solve the problem by using the 1st law of thermodynamics:
where
is the change of the internal energy of the system
Q is the heat (positive if supplied to the system, negative if dissipated by the system)
W is the work done (positive if done by the system, negative if done by the surroundings on the system)
In this case we have:
Q = -12 J is the heat dissipated by the system
W = -28 J is the work done ON the system
Substituting into the equation, we find the change in internal energy of the system:
b) terrestrial equator
c) tropic of Capricorn
d) tropic of Cancer
e) South pole

from directly overhead, and the rising/setting sun is never more than 23.5 degrees
from due east/west.
So this is the place where the path of the sun across the sky changes the
least during the year, and therefore the place where the lengths of day and
night change the least during the year.
