What are some ways in which the temperature of a substance can be measured

Juli2301 [7.4K]

The three most normal units of estimation for temperature are Celsius, Fahrenheit, and Kelvin.

A thermometer is an instrument that measures temperature. It can gauge the temperature of a strong, for example, food, fluid like water, or gas like air.

The Celsius scale is important for the decimal measuring standard. The decimal standard of estimation additionally incorporates units of mass, like kilograms, and units of length, like kilometers. Most logical fields measure temperature utilizing the Celsius scale. Zero degrees Celsius is the edge of freezing over water, and 100 degrees Celsius is the limit of water. Three countries don't utilize the Celsius scale. The United States, Burma, and Liberia utilize the Fahrenheit scale to quantify temperature. In any case, even in these nations, researchers utilize the Celsius or kelvin scale to gauge temperature. Water freezes at 32 degrees Fahrenheit and bubbles at 212 degrees Fahrenheit. The Kelvin scale is utilized by physicists and different researchers who need to record exceptionally exact temperatures. The Kelvin scale is the main unit of estimation to incorporate the temperature for "outright zero," the complete shortfall of any intensity energy.

A machine has a velocity ratio of 6 and is 80%efficient. What effort would be needed to lift a load of 300N with the aid of this

valkas [14]

Efficiency =Velocity Ratio/Mechanical Advantage *100%

80%=6/MA*100%
Therefore MA=7.5

MA=Load/Effort
7.5=300/E
E=300/7.5
E=40

*A car is going over the top of a hill whose curvature approximates a circle of radius 350m. At what velocity will the occupants

Scilla [17]

Answer:

v= 18.5 m/s

Explanation:

When at the top of the hill, the only force that keeps the car in the circular trajectory, is the centripetal force.

This force is not a new force, is just the net force aiming to the center of the circle.

In this case, is just the difference between the normal force (always perpendicular to the surface, pointing upward) and the force that gravity exerts on the car (which is known as the weight), pointing downward.
