Answer:
A compass can detect a magnetic field and show its direction. Iron filings can show the shape of a magnetic field. A gaussmeter can detect a field and indicate its strength.
Explanation:
Answer:
Vf = 44.27 m/s
Explanation:
When a ball is dropped it is acted upon by gravitational force under free fall motion. So, in order to find its final speed we use 2rd equation of motion, as follows:
2gh = Vf² - Vi²
where,
g = acceleration due to gravity = 9.8 m/s²
h = height lost = 100 m
Vf = Final Velocity = ?
Vi = Initial velocity = 0 m/s (Since, ball starts from rest)
Therefore,
(2)(9.8 m/s²)(100 m) = Vf² - (0 m/s)²
Vf = √(1960 m²/s²)
<u>Vf = 44.27 m/s</u>
Answer:
36 minutes
Explanation:
Distance= Time*Speed
Let time taken to go to city be x hours, therefore, time to travel back is (2-x) hours
The distance to and from the city are equal hence
15x=35(2-x)
15x=70-35x
50x=70 hence x=70/50=1.4 hours
Time to drive home will be 2-x=2-1.4=0.6 hours
0.6*60=36 minutes
Therefore, time to travel back home is 36 minutes
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.
