Answer:
ITS THE TOESSSSSSS FOR ME
A, yes because the plane is using air resistance and acceleration is increasing while it goes up. Although you don’t know speed, still yes.
The temperature scale which starts at absolute zero is the Kelvin scale. The correct option in respect to the given question is the last option. William Thompson was the British scientist and inventor that invented the Kelvin scale. William Thompson was also popularly known as Lord Kelvin.His discovery of the Kelvin scale is considered one among the three best scales in use for measuring temperatures.Each measuring unit of this scale is never called a degree but a Kelvin. This specialized scale gives the option of measuring temperature in both centigrade and Fahrenheit.
Answer:
4N
Explanation:
Given parameters:
Weight of stone when immersed in water = 18N
Weight of water displaced = 4N
Unknown:
Weight of the stone in air = ?
Solution:
To solve this problem, we employ the Archimedes' principles.
It states that the upward buoyant force on a body is equal to the weight of the fluid displaced.
The weight of the water displaced is equal to the weight of the body.
So, the weight of the stone in air = 4N
A basic mechanical device that is used for applying a force.
Examples are: inclined plane, lever, wedge, wheel and axle, pulley, and screw...Hope this helps, have a BLESSED and wonderful day!
