Explanation:
in a room with no windows that way it doesnt shatter. Usually a closet... or if you have a basement.sorry but that applies to all them
Answer: The weight of the air displaced by the balloon is less than the volume of the balloon.
Explanation:
A hot air balloon is a cloth wrap that contains several thousand cubic meters of air inside (a large volume of air). The burner heats the liquid propane to a gaseous state to generate a huge flame, which can reach more than 3 meters, thus heating the air mass inside the balloon. In this way,<u> its density is modified with respect to the air that surrounds it</u>, because the hot air is lighter than the outside air (less dense), causing the balloon to rise and float.
Now, if we know that the density of a body
is directly proportional to its mass
and inversely proportional to its volume
:

We can deduce that <u>by increasing the volume of the body, its density will decrease.</u>
This is proof of <em><u>Archimedes' Principle</u></em>:
<em>A body totally or partially immersed in a fluid at rest, experiences a vertical upward thrust equal to the mass weight of the body volume that is displaced.</em>
In this case the fluid is the air outside. So, the warm air inside the balloon, being less dense, will weigh less than the outside air and therefore will receive an upward pushing force or thrust that will make the balloon ascend.

Kirchhoff's loop rule is always true.
The foundation of circuit analysis is Kirchhoff's Laws for current and voltage. We have the fundamental set of tools required to begin evaluating circuits with these two principles, In an RLC circuit, the most fundamental elements of a resistor, inductor, and capacitor are connected across a voltage supply.

Answer:
A. T=126N
B. T=63N
Explanation:
To determine the tension in each given blocks, we first determine the acceleration of each block. It obvious that each mass will move with the same acceleration since the string connecting them is massless.
Hence using the equation of force we have
F=ma
Where m=total mass of blocks,
a=acceleration
F= force applied in this case the tension in the string.
For a 134 identical masses with an applied force of 134N, the acceleration of each mass can be computed as
134=134m*a
a=134/134m
a=(1/m )m/s²
a. To calculate the tension in the string between the 126 and 127 block, we use the equation below
T=ma
Since the number of blocks before the string is 126, we multiply the mass of each block by 126.
Hence the tension can be computed as
T=126m*a
Since a=1/m then
T=126m*1/m
T=126N
B.To calculate the tension in the string between the 63 and 64 block, we use the equation below
T=ma
Since the number of blocks before the string is 63, we multiply the mass of each block by 63.
Hence the tension can be computed as
T=63m*a
Since a=1/m then
T=63m*1/m
T=63N
