Answer:
Explanation:
Let's begin by explaining that the relation between the Celsius scale and Kelvin scale is:
This means the absolute zero point of the Kelvin scale is
Keeping this in mind, we have the freezing point and boling point of Methane as:
Freezing point:
Boiling point:
According to this, there is a linear relation between the methane scale () and the Kelvin scale in the form:
(1)
Where:
is the temperature in Kelvin
is the temperature in degrees Methane
Firstly, we need to find the value of and with the two given points ( and ):
When and :
(2)
When and :
(3)
Now we have the linear equation:
(4)
Isolating :
(5)
Evaluating for :
(6)
Finally:
This means
Answer:
in decimal form x = 1.5
in exact form x = 3/2
and as a mixed number x = 1 1/2
Explanation:
Answer:
Explanation:
Magnetic field due to a long wire
= 10⁻⁷ x 2i / r where i is current in the wire and r is distance of the point from the wire
In the given case magnetic field
B = 10⁻⁷ x 2i / r
= 10⁻⁷ x 2x 1.3 / .8 x 10⁻²
= 3.25 x 10⁻⁵ T
= 32.5 x 10⁻⁶ T
It will create a deflecting torque on the compass needle
Let after turning by angle θ , equilibrium point is reached
at this point , deflecting torque = restoring torque by earth's magnetic field
MB cosθ = MHsinθ , M is magnetic moment of magnetic needle , H is horizontal component of earth's magnetic field.
Tanθ = B / H
= 32.5 / 29
=1.20
θ = 50 degree approx .
The Sun shines on the moon which then shines back on the earth. Also the stars but thats very minimal
