Answer:
What Is Not an Element? If you don't see it listed on the periodic table, it's not an element! Element non examples include all compounds, which are substances made when two different types of atoms form a chemical bond. Any material made by mixing elements is no longer an element
Explanation:
Answer:
The 15 ⁰C measured at this altitude is above the standard temperature for the altitude.
Explanation:
The standard temperature at sea level is 15 degrees Celsius. It decreases about 2 degrees C (or 3.5 degrees F) per 1,000 feet of altitude above sea level.
235 meters is equal to 771 feet.
Using the formula below, we can estimate temperature loss due to this change in altitude, that is 771 feet above sea level.
temperature loss = (3.5 x Change in altitude)/1000ft
temperature loss = (3.5 x 771ft)/1000ft = 2.7⁰F, (32 -2.7 = 29.3 ⁰F)
this is equivalent to 1.5⁰C temperature loss.
Thus, the standard temperature of the engineering quadrangle at 235 meters above sea level is 13.5 ⁰C.
Therefore, the 15 ⁰C measured at this altitude is above the standard temperature for the altitude.
Weight equals mass multiplied by the acceleration due to gravity.
<em>Average velocity is defined as the ratio of change in position to the time taken for that change. </em>
Answer: <em>True</em>
Explanation:
Velocity is obtained by dividing the displacement of an object by time interval. Displacement is a vector quantity which is defined as the shortest distance between initial and final point of an object.
In other words, displacement is the change in position of an object. A position-time graph can be plotted to find the average velocity of an object graphically. The average velocity can be obtained by calculating the slope of the position-time graph.
While average velocity deals with velocity over a particular time interval, instantaneous velocity gives the velocity of an object at a particular point of time or instant.
Thermal energy can be transferred in a few ways but friction is a good example, other ways include, radiation, convection, or conduction.
