The average velocity of the object in moving from point-B to point-C is
(the straight-line distance and direction from point-B to point-C)
divided by
(the time the object takes to make the trip) .
Sometimes in the same direction but most of them go in the opposite direction
Answer:
Acceleration is a vector quantity which is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.
Answer:
Explanation:
The charge on 10μF capacitor = 10 x 12 x 10⁻⁶ = 120 μC
when it is connected with 20μF capacitor both acquires common potential whose value is
= 120 x 10⁻⁶ /( 10 +20) x 10⁻⁶ = 4 V.
Energy stored in 20μF capacitor =1/2 x 20 x 10⁻⁶ x 4 x 4 = 160 x 10⁻⁶ J.
Answer:
The acceleration of car is 6.67 m/s².
Explanation:
Given that,
Initial velocity = 30 m/s
Distance = 15 m
Final velocity = 10 m/s
Time = 3 sec
We need to calculate the acceleration
Using formula of acceleration
Negative sign shows the car is slowing down.
Hence, The acceleration of car is 6.67 m/s².
