Answer:
The total resistance of the circuit = 188ohms
Explanation:
potential difference = 25volts
For resistors in series, equivalent resistance
Rt = R1 + R2 + R3
Rt = 120 + 18 + 50
Rt = 188ohms
The total resistance of the circuit = 188ohms
It’s a force which acts on an object without coming physically in contract with it.
Answer:
3658.24m
Explanation:
Hello!
the first thing that we must be clear about is that the train moves with constant acceleration
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.

Vf = final speed
=160km/h=44.4m/s
Vo = Initial speed
=42.9km/h=11.92m/s
A = acceleration
=0.25m/s^2
X = displacement
solving

the distance traveled by the train is 3658.24m
I only know what number 1. is and its Mechanical Energy.
