Answer:
The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages

HOPE IT HELPS
Answer:
Isolated system
Explanation:
If we are talking about theremodynamic system answer is ISOLATED SYSTEM
If we talking about mechanic annswer is CLOSED SYSTEM
CLOSED SYSTEM IN CLASSICAL MECHANICS = ISOLATED SYSTEM IN THERMODYNAMICS.
Answer:
45.9m
Explanation:
Given parameters:
Mass of the ball = 1kg
Initial velocity = 30m/s
Unknown:
Height the ball will travel = ?
Solution:
At the maximum height, the final velocity of the ball will be 0;
Using ;
V² = U² - 2gh
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
h is the height
0² = 30² - (2 x 9.8 x h)
0 = 900 - 19.6h
h = 45.9m
Answer:
Sand: 28°C, 27°C, 26°C
Potting soil: 33°C, 29°C, 31°C
Mixture: 29°C, 29°C, 22.5°C.

Question:
<em>For an exothermic reaction at equilibrium, how will increasing the temperature affect Keq?</em>
Answer:
<em>The reaction will proceed towards the liquid phase. Heat is on the reactant side of the equation. Lowering temperature will shift equilibrium left, creating more liquid water. A reaction that is exothermic releases heat, while an endothermic reaction absorbs heat.</em>
<em>If you increase the temperature, the position of equilibrium will move in such a way as to reduce the temperature again. It will do that by favouring the reaction which absorbs heat. In the equilibrium, that will be the back reaction because the forward reaction is exothermic.</em>
