The answer is 50 i. e. C

Explanation:

If the potentiometer is assumed to be linear

Then one one quarter of the total resistance will be below the slider and three quarters of the resistance will be above the slider.

To get zero voltage reading, 150 must be 3/4 of the total resistance of the right leg

150 = 0.75(150 + R)

150 = 112.5 + 0.75R

37.5 = 0.75R

R = 50 Ω

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
