The transfer of energy means, in convention process, transport of matter. In this case, hot water has lower density than cool water. The water with less density ascends and leaves gaps that are occupied with cooler water "packages".

What factors does the speed of atoms depend on?
Vedmedyk [2.9K]
<h2>Answer:</h2>

The speed of atoms depends upon:

  • Temperature: Speed of atom is directly proportional to the temperature of atoms.
  • Pressure : It is also directly proportional to the speed of an atom.
  • Volume of gas : As the volume of gas increases, collision between atoms increases with increasing the speed of atom
  • Number of atoms surrounding: More number of atoms leads to more collisions, increasing speed of atoms.

The left face of a biconvex lens has a radius of curvature of magnitude 11.7 cm, and the right face has a radius of curvature of
SIZIF [17.4K]

Answer:

Explanation:

R1 = + 11.7 cm

R2 = - 18.7 cm

n = 1.52

(a) Use lens maker formula

\frac{1}{f}=\left ( n-1 \right )\left ( \frac{1}{R_{1}}-\frac{1}{R_{2}} \right )

\frac{1}{f}=\left ( 1.52-1 \right )\left ( \frac{1}{11.7}}+\frac{1}{18.7} \right )

\frac{1}{f}=\frac{0.52\times 30.4}{218.79}

f = 13.84 cm

(b)

R1 = + 18.7 cm

R2 = - 11.7 cm

n = 1.52

(a) Use lens maker formula

\frac{1}{f}=\left ( n-1 \right )\left ( \frac{1}{R_{1}}-\frac{1}{R_{2}} \right )

\frac{1}{f}=\left ( 1.52-1 \right )\left ( \frac{1}{18.7}}+\frac{1}{11.7} \right )

\frac{1}{f}=\frac{0.52\times 30.4}{218.79}

f = 13.84 cm

Does a stove have mechanical energy
Ainat [17]

-- Any object has gravitational potential energy relative to any place
lower than where the object is.  The stove in the kitchen has potential
energy relative to the basement floor.

-- If an object is not moving, then it has no kinetic energy. The stove has
no kinetic energy unless you throw it or drop it out of a window.
