PIT_PIT [208]

Answer:

Moment=Force x Pivot

Explanation:

A moment is the turning effect of a force. Moments act about a point in a clockwise or anticlockwise direction.

Law of moments:

When an object is balanced (in equilibrium) the sum of the clockwise moments is equal to the sum of the anticlockwise moments.

How to calculate moments:

Moment=Force x Pivot

Which temperature is the hottest, 200°C, 200°F or 200 Kelvin?
gogolik [260]

Answer:

200 °C

Explanation:

Let’s convert all the temperatures to the same scale, say, Celsius.

<em>Celsius</em>

Water boils at 100 °C, so 200 °C is the temperature of <em>superheated steam</em>.

<em>Fahrenheit </em>

Water boils at 212 °F, so 200 °F is <em>just below the boiling point of water</em>.

C = \frac{5 }{ 9}(F-32)

C = \frac{5 }{ 9}(200-32) = \frac{5 }{ 9}\times168 = 93 ^{\circ}\text{C}

<em>Kelvin </em>

Standard temperature is 0 °C = 273.15 K. Ice melts at 273.15 K (0 °C), so

200 K is <em>well below the melting point of ice</em>.

C = K – 273.15

C = 200 -273.15 = -73 °C

Thus, 200 °C is the hottest temperature.
