Answer: Hi, in this problem we should take the next assumption: If the system is closed, there should be a conservation of the total energy.

The total energy is the sum of the kinetic and the potential energy, so if the potential energy increases, then the kinetic energy should decrease in the same amount, so the total energy remains constant.

A 1 kg object sits on the earth’s surface. What is the force of gravity between the object and the earth? (mass of the earth = 5

snow_lady [41]

Answer:

9.81N

Explanation:

the force of attraction is given by

F=GmM/R²

where m is mass of the body

M is mass of the earth

R is radius of the earth

G is the universal gravitational constant(6.67x10-¹¹)

hence we substitute the values in the formula.

Answer:

check the point where the output device's field wiring is connected to the output rack. ( C )

Explanation:

Given that an indicator light on the output module is indicating that a signal has been sent to the output point where the failed single output device is connected , the best line of action to properly indicate the output device that has filed in the PLC system, is to check the point where the output device's field wiring is connected to the output rack in the PLC system.

A PLC system is a computer control system ( especially Industrial ) that helps in the monitoring the states of input and output devices in an industry.
