Give u = start velocity
v = end velocity
v = u + at
50 = 400 + a*30
30a = -350
a = -116.67 m/
**Why the accecleration is negative number**
Because displacement, velocity, and acceleration are VECTOR QUANTITIES.
Vector Quantity must have direction.
19-? Is the exact p.d across the 114-?resistor.
Current will different
But p.d will same in parallel circuit .
Answer and Explanation:
The answer would be: <u>Breakfast</u>
<u></u>
Breakfast would be the constant of this scenario because this doesn't change. The time of day (for eating eggs) will always be in the morning, so that wouldn't change.
Eating eggs would be the independent variable because you can change this value. This could be a different food or an amount of the food that is being eaten.
The grades would be the dependent variable because the score <em>depends</em> on the eating of eggs.
