RAdio Direction And Ranging
Answer:
Pushing from the same direction: 343 N
Pushing from opposite directions: 171 N
Explanation:
If Dani and Gina are pushing in the same direction then you would add up the forces they are pushing with since the force is applied in the same direction.
257N+86N=343 N
If Dani and Gina are pushing in the opposite direction then you would subtract the forces they are pushing with because they are going against each other.
257N-86N=171 N
Hope this helped! :)
The intensity of light is related to our perception of brightness.
Answer:
1) Average velocities:
Given the magnitudes of 2 velocity vectors, in different time instants, the average velocity is defined as the difference of the 2 velocity magnitudes, in absolute value, divided by the interval of time occuring between the measurement of the velocity magnitudes.
2) Average acceleration
Given the magnitudes of 2 acceleration vectors, in different time instants, the average acceleration is defined as the difference of the 2 acceleration magnitudes, in absolute value, divided by the interval of time occuring between the measurement of the acceleration magnitudes.
As you see the definitions are pretty similar.
