Yes. The line is increasing. The flat line at the top of the graph is where there is not acceleration and the decreasing line is deceleration.
Neither the speed nor the distance of a falling object is linearly related to time.
Answer:
A vibration or oscillation is a periodically repeated reversal of the direction of movement.
Explanation:
Une vibration ou une oscillation est une inversion répétée périodiquement de la direction du mouvement.
Here is just another definition.
A vibration is periodic back-and-forth motion centerd around it's equilibrium.
Answer: option 4: A wire that is 2-mm thick and coiled.
Explanation:
The current in each wire is same. The magnetic field due to a current carrying wire increases if the wire is coiled with the more number of turns. A thick wire would cause low resistance to the current. Hence, a 2-mm thick wire which is coiled would produce the strongest magnetic field.
Answer:
Explanation:
The time taken by the light to travel a given distance is defined as:
Here c is obviously the speed of light. Now we convert the average distance form Venus to Earth to meters:
Finally, we calculate the minutes taken by the light to travel from Venus to Earth:
