Calcium and boron react to form calcium boride, as represented by the chemical equation below.
Ca + 6 B → Cab6
Which type of reaction is shown by this equation?
A. double displacement
B. single displacement
C. synthesis
D. decomposition

it should be -8.6 cm hope this out

v=ir = 3x15 =45 v

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.
