Answer:
Independent variable: amount of sugar
Dependent variable: size of the loaf of bread
Explanation:
The amount of sugar the mother adds is completely up to her, and the size of the loaf changes according to that, which is why the loaf size is the dependent variable
The criteria of the indicator species that does not meet is:
<u>Found at the base of any food chain.</u>
<u>Option: B</u>
<u>Explanation:</u>
As an early warning system for environmental problems, indicator species are chosen for their sensitivity to environmental conditions. If the selected indicator species decrease in numbers or any health factor, it symbolizes to see for detrimental effects such as soil impurity, pollution in water/air, habitat fragmentation or drastic variation in climates.
Apart from being sensitive to change, these species must also be representative of the other organisms in the ecosystem, easily observable and must be sampled, and they should react continuously to environmental changes. So from the above conditions, it is clear that species found in any base of food chain is not the criteria.
The energy a charge has due to its position relative to other charges.
Answer:
<em>a. The cart's acceleration is 2 m/s^2</em>
<em>b. The cart will travel 100 m</em>
<em>c. The speed is 20 m/s</em>
Explanation:
a. The acceleration of the cart can be calculated using Newton's second law:
F = m.a
Solving for a:

The cart has a mass of m=15 Kg and is applied a net force of F=30 N, thus:


b.
Now we use kinematics to find the distance and speed:

The cart starts from rest (vo=0). The distance traveled in t=10 seconds is:


The cart will travel 100 m
c.
The final speed is calculated by:

The speed is 20 m/s
B. 0.5 km to the North. if its going 2 km/h, just take the time (.25 hours) and divide it by the speed, and you've got distance.
