Answer:
Both technicians are correct.
Explanation:
A working coil in a relay can measure resistance between 50 an 200 ohms.
And the terminals in a Relay are the next, considering the German International Automotive industry standard DIN 72552:
85 Coil
86 Coil
87 NO Normally open
30 Common
So Measuring between terminal 30 and 87 must be an open circuit, and the ohmmeter must show infinite resistance or "OL".
The force of earth gravity on the space craft is 1.19 N
\begin{array}{c}
F = \frac{{GMm}}{{{{\left( {r + h} \right)}^2}}}\\
= \frac{{6.67 \times {{10}^{ - 11}} \times 6 \times {{10}^{24}} \times 1050}}{{{{\left( {\left( {6400 + 12800} \right) \times {{10}^3}} \right)}^2}}}\\
= 1.139\;{\rm{N}}
\end{array}$
Hence, the force of gravity on the space craft is 1.19 N.
Answer:
No.
Explanation:
- According to Faraday's law, the induced emf in the circuit is given by :
, it is proportional to the rate of change of magnetic flux.
- In this case, a short piece of wire that is not attached to anything and move it up and down in a magnetic field. It means that the circuit is not completed here. It is an open circuit. For the induction of current, a circuit must be completed.
- Hence, no current will induce.
