Answer:
Explanation:
Let the internal resistance be r .
Since in open circuit the volt is 1.55 V , this will be the source voltage .
Source voltage = 1.55
If external resistance be R .
1.55 / (R + r ) = .500
R + r = 3.1 ohm
So sum of internal resistance and external resistance will be 3.1 ohm.
It’s important for a scientist to be open-minded because they need to be able to understand or creative anything that was never thought about. It’s also important for a scientist to be skeptical because some ideas or products that they hear about can have false factors. I hope this helped!
Answer:
Final velocity of the elevator will be 4.453 m/sec
Explanation:
Let mass is m
Acceleration due to gravity is g m/sec^2
Distance s = 2.2 m
As the elevator is moving upward so net force on elevator
So according to question
0.46 mg = ma
a = 0.46 g
a = 0.46×9.8 = 4.508
Initial velocity of elevator is 0 m/sec
From third equation of motion
So final velocity of the elevator will be 4.453 m/sec
