58 the number of protons are the same as your atomic number<span />
We know average speed =total distance/time taken
So avg speed=(85+63)/(5+5)=14.8km/hr

Explanation:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.
The coefficient of friction (fr) is a number that is the ratio of the resistive force of friction (Fr) divided by the normal or perpendicular force (N) pushing the objects together. It is represented by the equation: fr = Fr/N.
Answer: large intestine
Explanation:
mouth grind and moisten food
saliva break down starch into sugar
esophagus transport food from mouth to stomach
stomach churn food, break down food with enzymes
liver add bile to break down fat
pancreas add enzymes to digest protein
gallbladder store bile
small intestine absorb food through villi
large intestine absorb extra water and remove waste from body
In the thermal equilibrium, the change in temperature is said to be zero in between the bodies. Thermal equilibrium is reached when both objects have the same temperature.
<h3>What is thermal equilibrium?</h3>
Thermal equilibrium is easily explained by the zeroth law of thermodynamics. If any two-body is at thermal equilibrium there is no change in the temperature of the body.
According to zeroth law if body A is in thermal equilibrium with body B and body B is in thermal equilibrium with C . So body A and C are also in thermal equilibrium.
In the thermal equilibrium, the net heat transfer is said to be zero in between the bodies.
Hence option A IS RIGHT. Thermal equilibrium is reached when both objects have the same temperature
