Electromagnets can easily be turned on and off.
Explanation:
An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil".
When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.
You can look on the manufacturers website or packaging. generally it will have rp-sma antenna connectors
Answer:
‼️‼️‼️155.4 calories‼️‼️‼️
Explanation:
1 gram of fat = 9 calories
1 gram of carbohydrates = 4 calories
1 gram of protein = 4 calories
11x9 = 99
1.1x4 = 4.4
13x4 = 52
This would get you go this question thus the answer to your question
99 + 4.4 + 52 = 155.4 calories
Answer – C (Using instruments that have not been calibrated).
When the integrity of an instrument’s calibration has been compromised (usually due to exposure to a shock, vibration, or physical damage), it needs to be calibrated; failure to do this inevitably leads to inaccurate measurement; this is a very common measurement error.
