<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.
Answer:
Explanation:
R1 = + 11.7 cm
R2 = - 18.7 cm
n = 1.52
(a) Use lens maker formula



f = 13.84 cm
(b)
R1 = + 18.7 cm
R2 = - 11.7 cm
n = 1.52
(a) Use lens maker formula



f = 13.84 cm

What is Newton's second law of motion?
<h2><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u>:-</h2>
Newton's second law of motion states that the rate of change of momentum is directly proportional to the applied force and the direction of change of momentum takes place towards direction of applied force.

-- 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.
