Answer:
specific heat of the substance
Answer:
One may assume that the planet radiates energy like a blackbody at some temperature according to the Stefan–Boltzmann law. Thermal equilibrium exists when the power supplied by the star is equal to the power emitted by the planet. The temperature at which this balance occurs is the planetary equilibrium temperature.
Explanation:
Explanation:
velocity gradient= velocity/distance
For the position of button we can use force balance as
Friction Force = Centripetal force
so here we will have
here we know that
R = radius of circle where button is placed
f = 35 rev/min
now from above equation
so friction coefficient will be 0.33
A solution is a homogeneous mixture of two or mores substances at molecular level mainly solute and solvents. A solution may be saturated, supersaturated or unsaturated. A saturated solution is when the solution has dissolved the maximum solute at a given temperature, unsaturated solution is a solution which can still dissolve more solute at a given temperature to achieve saturation. In this case, if a solution is forced to dissolve more solute than it normally can dissolve, the solution is supersaturated.
