Answer:
A flame always point upwards because the flame's gas is hotter than the surrounding air and, like you said, a hot gas is always lighter or less dense than a cold gas.
Explanation:
The acceleration is 3 m/s per minute, or 0.05 m/s per second.
Hello,
The answer should be option D "specific heat".
Reason:
Specific heat is what tells the person how my heat and or pressure is required to raised the objects temperature. Its not option A convection because I'm convection is mainly used as like the ozone layer and the suns rays. Its not option B radiation because radiation doesn't tell the person what temperature it needs in order for it to rise its more like its already rises and hot. Its also not option C because conduction is the process of a object heating another object therefore the answer is option D.
If you need anymore help feel free to ask me!
Hope this helps!

Electron as a free particle
Explanation:
Free electrons,the electrons which are not attached to the nucleus of a atom and free to move
Answer
given,
Mass of the solid sphere = 1800 Kg
radius of the sphere,R = 5 m
mass of the small sphere, m = 2.30 Kg
when the Point is outside the sphere the Force between them is equal to
when r>R
When Point is inside the Sphere
when r<R
where r is the distance where the point mass is placed form the center
Now Force calculation
a) r = 5.05 m
[/tex]
F = 1.082 x 10⁻⁸ N
b) r = 2.65 m
