B. 17 m/s
C. 21.5 m/s
D. 19.5 m/s
Since the acceleration is constant, the average velocity is simply the average of the initial and final velocities of the body:
We can proof that the distance covered by the body moving at constant average velocity is equal to the distance covered by the body moving at constant acceleration a:
- body moving at constant velocity : distance is given by
- body moving at constant acceleration : distance is given by
Period is defined as the time required to complete one cycle which is also related to frequency. Period is presented by an equation P = 1/f where p is the period, and f is the frequency. The unit is in second. Frequency is defined as the number of circular revolutions in a given time interval and it is in Hertz (Hz) = 1s^-1. Velocity s defined as the arc traveled at a given time with the equation v=l/t where v is the velocity, l is the length and t is time. The unit is in m/s.
B. compounds
C. Molecules
D. atoms
Molecules collide and create a movement of heat called conduction.
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

Answer:
c.
Explanation:
Answer:
False
Explanation:
Inattentionla blindness is a condition that happens when you overview or do not notice an object that is not supposed to be in a certain place and that is strange for its context because you are paying attention to something else, this means that if you do a task that needs a great deal of attention you will actually increase the inattentional blindness.
