In 2011, a professional climber scaled the outside of Burj Khalifa making it all the way to 828 meters in 6 hours. how far did they climb in the first 2 hours?

Given:

Professional climbers climb 828 meters in 6 hours.

To find:

how far did they climb in the first 2 hours?

Solution:

According to the question,

In 6 hours, they climb 828 meters.

In 1 hour, they climb meters.

In 2 hour, they climb meters.

Now, the distance they climb in the first 2 hours is

Therefore, they will climb 276 meters in first 2 hours.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
