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
Answer: a) The Answer to the question is option a) None of it.
Explanation:
The reason is because according to the law of conservation of energy Energy can neither be created nor destroyed but can be transformed from one form to the other. Therefore none of the kinetic energy was dissipated, rather it was transformed to another form of energy.
<span>You have just demonstrated an insight learning. Internal insight occurs if one learned a new way without the help of environmental factors. In here, what the person initially learned that if one saw a broken light bulb from a lamp, he can be cut through the jagged glass if one does not wear a pair of gloves. And maybe because at the moment, the person could not find one, he felt using a cut potato to pick up the pieces of the broken lamp. This is a demonstration of insight learning. The person found a way to pick up the pieces of the broken lamp by using his instinct at the moment. The person is not influenced by an outside source to tell him to use a potato. </span>
Answer:
An open system can exchange both energy and matter with its surroundings. The stovetop example would be an open system, because heat and water vapor can be lost to the air. A closed system, on the other hand, can exchange only energy with its surroundings, not matter.
Explanation:
Answer:
A
Explanation:
Velocity means speed with a direction. Unless the speed changes too, or it has an increase in speed, the answer would be different. Here, the direction changes, making the velocity change.
