Answer:
45.09 m/s^2
Explanation:
from the question we were given the following parameters
mass = 931.9 kg
initial velocity (V1) = 0 m/s ( since it started from rest )
final velocity (V2) = 25.7 m/s
time (t) = 0.57 s
The average acceleration is given by:
a = ( V2 - V1 ) / t
therefore
a = (25.7 - 0) / 0.57 = 45.09 m/s^2
Answer:
T = 2.4 + 2.4 = 4.8 [s]
Explanation:
In order to solve this problem, we must use the following kinematics equation and calculate the acceleration value.
Vo = inital velocity = 0
x - xo = 15 [m]
t = time = 2.4 [s]
15 = 0.5*a*(2.4)^2
a = 5.208 [m/s^2]
We can use the same equation to find the time.
30 = 15 + 0.5*(5.208)*t^2
t = 2.4 [s]
T = 2.4 + 2.4 = 4.8 [s]
Due to difference in electric potential.
<h3>What is Potential difference?</h3>
The amount of work in an electrical field to move a unit charge from one place to another is known as the electrical potential difference.
Here , the potential difference is the difference in electric potential between two charged substances.
Current is the flow of charges from one end end to another end of a conducting wire connected across a two terminals of a battery.
The potential difference is [provided by the battery across the two terminals due which the charges flow.
Current flow is from positive to negative terminals, indicating the movement of positive charges in that direction.
Hence , potential difference causes the electric charges to flow from one end of the battery .
