Answer:
536.448m/s or 20miles/hr
Explanation:
Speed is defined as the distance travelled by a body or an object in a specified time.
Speed = Distance/Time
If a hurricane travels a distance of 20 miles in 1 hour.
Distance travelled = 20miles
Time taken = 1hour
Speed = 20miles/1hour
Speed = 20miles/hr
Since 1mile = 1609.344m
20miles = 20×1609.344
20miles = 32186.88m
1hour = 60seconds
Expressing the speed in m/s
Speed = 32186.88m/60s
Speed = 536.448m/s
Answer:
Explanation:
When we add salt to water entropy of the system increases because some amount of energy is released as salt dissolves in the water due to the dissociation of ions.
Therefore entropy of the system after the salt dissolves is highest among them all and the least entropy is associated when mixing begins.
Entropy is the degree of randomness and it increases when salt dissociates to
as these ions are freer to move inside an aqueous solution compared to Previous state.
Yes. Kinetic energy is a form of mechanical energy and friction will turn that kinetic energy into heat.
