Explanation:
The five basic postulate of kinetic molecular theory includes:
1) All gases consist of large amount and numbers of tiny particles that are far apart from each other and also relative to their size.
2) The collisions between gas particles and gas particles against container walls is refer to as elastic collision.
3) All gas particles are in a continuous random and rapid motion. They possess kinetic energy which is energy of motion.
4) There are no attractive force between gas particles.
5) The temperature of a gas depends on the average kinetic energy of the gas particle.
Answer:
Explanation:
power of a heating element = V² / R where V is voltage and R is resistance
putting in the values
5200 = 75² / R
R = 1.082 ohm
Formula for resistance
R = ρ L / S , ρ is resistivity , L is length and S is cross sectional area
1.082 = 5 x 10⁻⁷ x L / (3.83 x 10⁻⁶)
L = 8.29 m
b )
power of a heating element = V² / R , R is new resistance
5200 = 120² / R
R = 2.77 ohm
R = ρ L / S , ρ is resistivity , L is length and S is cross sectional area
2.77 = 5 x 10⁻⁷ x L / (3.83 x 10⁻⁶)
L = 21.22 m

same distance from the mirror as the object
same size
lateral inversion
<u>Explanation</u>
The image formed by a plane mirror is formed at equal distance from the mirror as the object is.
The size of the image is the same as the size of the object.
The image is laterally inverted. This means that, when a person lifts his right hand, his or her image will raise it's left hand.
