Which hypothesis is supported by your observations of the teacher demonstrations? Question 9 options:

If the resistance in a circuit increases, then the speed of the electrons increases.

If the resistance in a circuit increases, then the speed of the electrons decreases.

If the resistance in a circuit increases, then the speed of the electrons stays the same.

the answer for apex is the lowest

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.

given values:

mass = 0.3 kg.

conservation of mass

mass before something happens = mass afterwards
