Answer:
yes
Explanation:
As the formula is α= ΔL/L*ΔT where alpha (α) is the sign of coefficient of linear expansion
Answer:
Carbon and oxygen
Explanation:
White dwarfs are the stars which have used all their hydrogen and helium fuel and now exists with only carbon and oxygen in their core. Their size reduces up to one hundredth times of the size of their sun in early stages and yet they possess the same mass.
Due to loss of fuels and impact of gravity, a young star collapses on itself leading to formation of dwarf star.
Answer:
11250 N/C
Direction: 0 deg counterclockwise from positive x-axis
Explanation:
= magnitude of charge on each particle = 5 μC = 5 x 10⁻⁶ C
= distance of each particle from center of circle = 2 m
= Magnitude of electric field at the center by each particle
Magnitude of electric field at the center by each particle is given as

inserting the values

From the diagram , we see that being equal and opposite, the electric fields due to charge q₁ and q₃ cancel out.
So net electric field at center is only due to charge q₂ direction towards positive x-direction
So
= Resultant electric field = 11250 N/C
Direction: 0 deg counterclockwise from positive x-axis
Answer:
the magnitude of the dog's total displacement to the nearest tenths = 53.12°
Explanation:
Given that:
a dog walks 8.0m due to the north and 6.0 m due east.
We can determine the magnitude of the dog's total displacement by using the Pythagoras theorem.
Consider the north direction be the opposite and the east direction to be the adjacent, therefore the hypotenuse will be the dog's total displacement.
So, suppose hypotenuse is represented by a
the opposite represented by b, and the adjacent represented by c
Then;
a² = b² + c²
a² = 8² + 6²
a² = 64 + 46
a² = 100
a =
a = 10.0 m
However, the magnitude of the dog's total displacement is calculated by taking the tangent of the system.
tan θ = opposite / adjacent
tan θ = b/c
tan θ = 8/6
tan θ = 4/3
tan θ = 1.333
θ = tan⁻¹ (1.333)
θ = 53.12
the magnitude of the dog's total displacement to the nearest tenths = 53.12°
We would observe that the light went out and the heat turned off.
Since the sun's mass didn't change, the Earth's orbital motion
wouldn't change, but that would not matter any more.
Our continued existence would be just a matter of time, and
not much of it.
