The absolute zero temperature is the smallest thermodynamic thermal limit, which is considered as a zero kelvin when the enthalpy, as well as the entropy of a cooled ideal gas, are of minimal value.
It is expressed by using the formula:
[tex]\mathbf{T_{abs} = T_N + k}[/tex]
where;
[tex]\mathbf{T_{abs } = absoulte \ temperature}[/tex]
[tex]\mathbf{T_N = temperature \ at \Neptune \ Scale}[/tex]
k = factor to convert temperature from absolute scale to Neptunian scale
N:B: An absolute temperature = zero (0) kelvin
From the information given, Using Ideal gas since it is used in Neptune:
PV = nRT
where;
P = pressureV = volumen = no of molesR = rate(constant)T = temperatureFrom the question, provided that the gas is the same and no new mass is added;
Then, we can equate the moles of gas in the given conditions as;
[tex]\mathbf{\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}....\dfrac{P_nV_n}{T_n}}[/tex]
Using:
[tex]\mathbf{\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}}[/tex]
where the value of;
P₁V₁ = 28 dm³ atm
T₁ = 0⁰ N
P₂V₂ = 40dm³ atm
T₂ = 100⁰ N
∴
[tex]\mathbf{\dfrac{28}{(0+K)}=\dfrac{40}{(K+100)}}[/tex]
By cross multiply;
28(K+100) = 40(0+K)
28K + 2800 = 0 + 40K
40K - 28K = 2800
12 K = 2800
K = 2800/12
K = 233.33° N
Recall that:
[tex]\mathbf{T_{abs} = T_N + k}[/tex]
[tex]\mathbf{0= T_N+ 233.33 ^0 N}[/tex]
[tex]\mathbf{ T_N= - 233.33 ^0 N}[/tex]
Therefore, we can conclude that the value of the absolute zero of temperature on their temperature scale is -233.33° N

(2) 1 m = 100 cm, so
(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m
(3) 1 km = 1,000 m, so

A bowling lane is 18 meters long. How long would it take a 1.5 m/s bowling ball to
roll down that lane?
16.5 seconds
16.5 meters
12 seconds
27 seconds
27 meters
12 meters
Divide distance by speed:
18 meters / 1.5 meters/ second = 12 seconds
Answer: 12 seconds
A bowling lane is 18 meters long. it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane, therefore the correct answer is the third option
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
The mathematical expression for velocity is given by
velocity= total displacement/Total time
As given in the problem a bowling lane is 18 meters long and the ball is moving with a velocity of 1.5 m/s in the roll-down lane we have to find the time period for the bowling ball to roll down that lane
Total displacement = 18 meters
the velocity of the ball = 1.5 m/s
time =?
By substituting the values in the formula of the velocity
1.5 = 18/t
t= 12 seconds
Thus , it would take 12 seconds for a 1.5 m/s bowling ball to roll down that lane

Does a fan that is not spinning have energy?
Answer:
Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.
In vector diagrams, what does the length of the arrow tell you?
Answer:
The length of the arrow tells you the size of the quantity in the vector diagram.
The direction of the arrow simply tells you the direction
Answer and Explanation:
A vector in this sense is a thing that has both magnitude (length) and direction.
Say you're walking at a speed of 5 miles per hour. If you keep walking in a straight line, then in two hours you will have walked 10 miles.
This doesn't give any information about where you started or any information about where you ended up after those 2 hours.
This is because "speed" is a scalar. It's a number with no associated geometry. It's just a magnitude. It's the magnitude of velocity.
Velocity is a vector.
Look on a map at where you are right now. Call that the center of the circle. Draw the circle with a 10 mile radius around where you are now.
The length of the arrow represents all of the possible places you could be after a two hour walk.
Which direction the arrow was pointing is what allows your friends to meet you there without checking along a ~63 mile path to find you or searching ~314 square miles to find you if you slowed down or stopped off along the way.

a 16 Watt bulb is used for 5 hrs. what is the energy consumed by the bulb
Energy = (power) x (time)
Energy = (16 watt) x (5 hours)
Energy = 80 watt-hours
or
Energy = 0.08 Kilowatt-hours
or
1 watt = 1 joule/second
5 hours = 18,000 seconds
Energy = (16 joule/sec) x (18,000 sec)
Energy = 288,000 Joules
Explanation:
A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.
(16×5 ) watt-hour=80Wh.
Convert it to kilowatt-hour i.e 0.08 KWh/day.
So 0.08 KWh is the energy consumption for one day.

A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?
Answer:
[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]
Explanation:
We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F= \ m \times a[/tex]
1. Calculate AccelerationThe mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).
[tex]v_f=[/tex]10 m/s [tex]v_i=[/tex]0 m/s t= 5 sSubstitute these values into the formula.
[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s[/tex]
[tex]a= 2 \ m/s^2[/tex]
2. Calculate ForceNow we know the mass and acceleration of the wheelbarrow
m= 20 kg a= 2 m/s²Substitute the values into the force formula.
[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]
[tex]F= 40 \ kg*m/s^2[/tex]
Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.
[tex]F= 40 \ N[/tex]
Answer:
40 N
Explanation:
We know that
F = ma
and
a = (v - u)/t
So,
F = m(v - u)/t
F = 20(10 - 0)/5
F = 20(10/5)
F = 20(2)
F = 40 N

does the object fall just during the 2nd second (i.e., from time t= 1 s to t = 2 s)?
Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per
second. Answer B is wrong because velocity increases. Answer C is wrong because the
distance increases every second. Ans. E is wrong because the derivative of distance with
respect to time gives the velocity, not the acceleration.
