Which will ensure laboratory safety during the experiment? Check all that apply. using beaker tongs to handle the hot beaker

reading the thermometer accurately

checking the beaker for chips prior to heating on the hot plate

using a beaker instead of an Erlenmeyer flask

turning off the hot plate after use

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.

explanation:

i can do 50 in a row ( but i get so tired after that)

see earlier

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.
