What do we mean by principle of conservation?​

What should the power status of a circuit be when measuring resistance with an ohmmeter?

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
