Answer:

The change in gravitational potential energy of the climber-Earth system,\Delta E=4.49\times 10^5\ J

Explanation:

Given that,

Mass of the hiker, m = 85 kg

Time, t = 2 h

Vertical elevation of the climber, h = 540 m

We need to find the change in gravitational potential energy of the climber-Earth system. We know that due to change in position of an object, gravitational potential energy occurs. It is given by :

\Delta E=mgh\\\\\Delta E=85\times 9.8\times 540\\\\\Delta E=4.49\times 10^5\ J

So, the change in gravitational potential energy of the climber-Earth system is 4.49\times 10^5\ J. Hence, this is the required solution.

1 The question asks for a certain quantity of examples in a list (Name 6 factors that contributed to the start of World War I, What 3 subatomic particles constitute an atom? etc).
2 The question is academically precise and, therefore, indecisive in the wording (What are the 2 kinds of loading most professional engineers and academics in the field of engineering today generally consider to be relevant in most cases when considering typical types of structure usually made of common materials using well-understand methods?)
3 The question challenges the answerer to defend a position as opposed to merely rattling off a list based on knowledge alone, thereby invoking higher levels of Bloom's Taxonomy. (What are 4 arguments that could be used to defend arguments made by the physicists of the day that electromagnetic waves must move through an illusive substance called 'the ether?)

What is the approximate increase in size from a 1 w to a 2w carbon resistor?
zepelin [54]
Since the 2-watt jobber has to dissipate twice as much power as the smaller unit I would expect it to have double the surface area. So if they are the usual cylindrical striped resistors then the larger one could have either double the length or else 1.4 times the radius of the smaller one.

When an athlete holds a barbell overhead, the reaction force is the weight of the barbell on his hand. how does this force vary
Sonja [21]
The force applied by the competitor is littler than the heaviness of the barbell. At the point when the barbell quickens upward, the power applied by the competitor is more prominent than the heaviness of the barbell. When it decelerates upward, the power applied by the competitor is littler than the heaviness of the barbell.
