Answer:
True
Explanation:
Understanding the relationship between change in velocity with time will explain to you how the object is accelerating or decelerating. This means acceleration is a ratio calculated from the change in velocity of an object and change in time. In a velocity time graph, the y-axis represents the velocity and the x-axis represents the time.
The slope of the graph m = Δ y-axis values/Δ x-axis values
m= Δvelocity / Δ time
m= Δ v / Δ t ------this the definition of acceleration so;
a= Δ v / Δ t
Conclusion : The slope/gradient of a velocity -time graph is acceleration.
Answer:
3.33 ohms
Explanation:
Parallel circuit :
1/Rtotal= 1/R1 + 1/R2 + 1/R3
1/Rtotal= 1/10 + 1/10 + 1/10
1/Rtotal=3/10
Therefore it Rtotal= 10/3=3.33 ohms
Answer:
Distance, x = 5.7 m
Explanation:
We have,
Acceleration of the car is -8.7 m/s²
It is required to find how far will the car travel while coming to a complete stop if its initial speed was 10 m/s. Using third equation of kinematics to find it as :
So, the distance covered by the car is 5.7 m.
Answer:
c will have the largest charge
Explanation:
because more lines are coming more line means more foce is required
25Wwwwwwwww has a greater resists
