SciTech needs to hire an engineer to develop a prototype for a project. The company asks each engineer to provide a cost and time estimate for the work. Each bid is shown in the table. Which engineer would be the most cost-effective for the project?

Camilla
John
Nora
Oracio

Oracio

Explanation:

Mutiply the cost per hour by the time to complete the job

Camila 40x20=800

John 30x30= 900

Nora 20x40=800

Oracio 15x50=750

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
