Answer:
an oscillator consisting of a material point of m = 200g vibrates under the action of an elastic force according to the equation y = 0.2sin (π / 4 • t + π / 16) (m)
calculate the period and frequency of the oscillation
calculate the speed and acceleration
calculate the Total Energy
Okay! Thank you for this knowledge
Answer: When electricity flows through it.
Explanation:
The electromagnet exhibits magnetic properties only as soon as current flows through the nucleus. Namely, the electric current in the space around the electrical conductor through which it passes creates a magnetic field. Unlike a permanent magnet, which has a permanent property of magnetism, the electromagnet is a temporary magnet because the magnetic field also disappears when the current ceases.
Answer:
W = 30 N
Explanation:
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
![(70\ N)(40\ cm - 10\ cm)-(30\ N)(50\ cm-40\ cm)-(W)(100\ cm - 40\ cm) = 0\\W(60\ cm) = (70\ N)(30\ cm)-(30\ N)(10\ cm)\\\\W = \frac{1800\ N.cm}{60\ cm}](https://tex.z-dn.net/?f=%2870%5C%20N%29%2840%5C%20cm%20-%2010%5C%20cm%29-%2830%5C%20N%29%2850%5C%20cm-40%5C%20cm%29-%28W%29%28100%5C%20cm%20-%2040%5C%20cm%29%20%3D%200%5C%5CW%2860%5C%20cm%29%20%3D%20%2870%5C%20N%29%2830%5C%20cm%29-%2830%5C%20N%29%2810%5C%20cm%29%5C%5C%5C%5CW%20%3D%20%5Cfrac%7B1800%5C%20N.cm%7D%7B60%5C%20cm%7D)
