Ais a system that uses vertical posts which are separated to support a horizontal beam.
a. truss
c. post-and-lintel
b. load-bearing
d. crenellation

A post-and-lintel is a system that uses vertical posts which are separated to support a horizontal beam. The answer is letter C. The horizontal beam is called the lintel and must not easily break. This type of system is mostly the basis of buildings nowadays.

less than one you can't create energy

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.
