Answer:
scalar quantity
Explanation:
Vector quantities have two characteristics, a magnitude and a direction. Scalar quantities have only a magnitude.
Lol, I remember I helped my sister with this question but anyways, the card flew because of inertia and the quarter fell in the glass because of gravity :).
Answer:
Experimental
Explanation:
Here the dependency of pressure on the temperature is to be determined. For finding this factor we need to calculate the pressure of the object at different temperature.
The process of calculating pressure for different temperature is experimental investigation because we need to perform this experiment for finding these value. On the basis of observed values the we can conclude the dependency.
Thus, this investigation is experimental.
Answer: Because the angle of attack is so high, a lot of momentum is transferred downward into the flow. These two features create a large amount of lift force as well as some additional drag.
Brainlest would be much appreciated.
Answer:
Quantity of heat or heat energy
Explanation:
the quantity of heat is the calculation of the total quantity of thermal energy in an object. it's S.I unit is joules (J) and the symbol for calculating it is Q.
