Select all numbers that are correctly rounded.

a. 1.578 rounded to 1.57
b. 12.82 rounded to 12.8
c. 3256 rounded to 3250
d. 0.0259 rounded to 0.026

So the correctly rounded answers are B and D

Explanation:

12.82 rounded to 12.8

This is correct, because it rounded down from 2, which is what it's supposed to do.

0.0259 rounded to 0.026

This is correct, because it rounded up from 9, which is what it's supposed to do. :)

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
