Answer:
Explanation:
The initial velocity, u, of the car=15m/s
The final velocity, v, of the car =0m/s
Time, t, taken for the car to come to a stop=5s
Acceleration is calculated by,
By substitution,
The negative sign implies that the car has decelerated.
The tiny particles that make up elements are called "molecules"
Answer:
Explained
Explanation:
It is possible for the voltage amplitude across the capacitor to be greater than the voltage amplitude across the source because it is gonna charge to its peak and will add up the voltage level.Moreover,ac capacitance of capacitance can be changed by introducing di electric
so voltage can be changed !!!
