In the study of Physics, the "Universal Gas Law" is not considered a law at
all.true or false
Answer: It’s False hope this helps
Explanation:
The answer is False, the Universal Gas Law" is considered law in Physics.
The universal gas law is considered law in physics and it states that the product of the Pressure and Volume of a given mass of gas is equivalent to the product of the number of moles, Boltzmann constant, and the temperature.
It is also known as the Ideal gas equation and is expressed mathematically as:
PV = nRT where:
P is the pressure
V is the volume
n is the number of moles
R is the Boltzmann constant
T is the absolute temperature.
Hence from the above definition, we can see that Universal Gas Law" is also considered a law in physics. The answer is False

The temperature at which water leaves the boiler is?
Answer:
The average setting for a gas-powered hot water boiler is 180°F. This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat.

What would make oppositely charged objects attract each other more?
o increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object
O decreasing the positive charge of the positively charged object and decreasing the negative charge of the negatively charged object
O increasing the distance between the positively charged object and the negatively charged object
O maintaining the distance between the positively charged object and the negatively charged object
Answer:
a: increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object
Explanation:
The oppositely charged objects attract each other more is option a. It increased the positive charge and the negative charge.
The Attraction of the oppositely charged:At the time when the oppositely charged objects are attracted to each other more so here the positive charge should be increased with respect to the positive charge object and the negative charge is increased with respect to the negative charge object

Which of the following best represents R=A+B ?
A)
B)
C)
Answer:
C
Explanation:
Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.
Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)
The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.
What is a vector quantity?The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.
Examples of vector quantities are displacement, velocity acceleration, force, etc.
As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,
The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.
Thus, the correct answer is option C.

a car is traveling north. can its acceleration vector ever Point South? explain
When a car is traveling north, its acceleration vector can point south when it is slowing down.
A vector quantity has both magnitude and direction. The direction of a vector is always shown by the direction to which the arrow points.
If the car is travelling north, the direction of the acceleration vector will continue to point northwards.
However, when the car slows down, the direction of the accelerating vector will now point southwards.

A bicyclist steadily speeds up from rest to 6.00m/s in 7.30s.
How far did she travel during this time?
Answer:
21.899 m
Explanation:
The explanation here is a little differe because we are starting from rest. So, everyone does physics a little differently, but what I would start with is trying to find the accelaration. I've given the formula, now you are able to plug this into the displacement formula where you Velocity Initial = 0m/s (Since you are starting from rest) and V final = 6.00 m/s...
You just plug numbers into the formula after solving for accelaration and do some simple algebra! I hope this helps! I am attaching a new pdf for visuals! If you can't open it let me know! Also there is a star by accelaration because I didn't know if I spelled it right, sorry!
