<span>Heat comes from stove flame to the sauce pan by radiation through infrared energy, heat conducts the metal of the sauce pan; Convection brings cool water to the hot surface at the bottom of the hot sauce pan until all or most of the water is hot enough to boil.</span>
The maximum force of friction:
F = μ* N, where μ is the friction coefficient and N id the force of the doghouse normal to the surface.
N for a flat surface would be: N = m*g, where m is the mass and g is the gravitational acceleration = 9,81 m/s².
Combined:
F = μ * g * m
A molecule, would be the correct answer
Answer:
The time taken by the ship to cover the distance, t = (x/25) s
Explanation:
Given data,
The initial velocity of the ship, u = 20 m/s
The final velocity of the ship, v = 30 m/s
The average velocity of the ship, V = (20 + 30)/ 2
= 25 m/s
The distance covered by the ship, d = x m
Then the time taken by the ship to cover the displacement is,
d = V x t
∴ t = d / V
Substituting the values,
t = x / 25
t = (x/25) s
Hence, the time taken by the ship to cover the distance, t = (x/25) s
The correct answer would be 1.35m/s sw.
