I think the answer is c. the more characteristics they have in common. Sorry if wrong.
Answer:
Total power generation will be 291.465 MW
Explanation:
We have given that river is flowing at rate of V =
Average speed v = 3 m/sec
Height h = 58 m
We know that total mechanical energy is given by
E = KE +PE
Energy per unit mass
Total power generation from the river is given by
So
The object that is subjected to a steady centripetal force moves in a circular motion. If this force suddenly disappear, the object moves in a direction tangential to the circle with respect to the last direction of the centripetal force.
Answer:
The force on each wire is
Explanation:
From the question we are told that
The acceleration at which the elevator will stop is
The weight of each section of the wire is
Generally here are weight at each section
Generally considering the first section, the force acting along the y-axis is mathematically represented as
Here represents the tension on the wire at the first section while represents the weight of the lamp at the first section
So
=>
=>
=>
Generally considering the second section, the force acting along the y-axis is mathematically represented as
=>
=>
=>
=>
Generally considering the third section, the force acting along the y-axis is mathematically represented as
