Answer: option c. as the force on a spring increases, the distance it stretches increases.
Explanation:
Hooke's Law relates the force (F) applied on the spring and extension (x) of the spring:
F = - k x
Where, k is the spring constant.
as the force on a spring increases, the distance it stretches increases but it is limited by its elastic limit. The negative sign means that spring force is a restoring force which means that the stretch of the spring is in opposite direction to force.
Answer:
The velocity of the sound waves across the plains of Sneedville is 500 m/s.
Step-by-Step Explanation:
Distance travel by the screech of Sneetches = d = 250 m
Time taken to cove 250 meters = t = 0.50 s
Let the velocity of the sound waves be v, such that:
v = d/t
⇒ v = 250/0.5
⇒ v = 500 m/s
Answer:
Independent variable: washer detergent
Dependent varaible: cleaing power of effectivenes of the detergent.
Explanation:
When an experiiment is performed there exists one independent variable, one dependent variable, and some other variables that must be controlled.
The goal of the experiment is to test a hypothesis, which is a statement that relates an effect with a cause and that must be proved true or false.
The effect in the dependent variable, and the cause is the independent variable.
Jenny (the scientist) wants to show how an effect or phenomenun, the dependent variable, is explained by the explanatory, independent, variable.
In the stated experiment, Jenny wants to know how the effectiveness of a new brand detergent and an old one compare with each other. Therefore, she designs a test in which she will determine how the brand of detergent may explain (explanatory or independent variable) the cleaning power or effectiveness, the dependent variable.
Jenny only can manipulate the independent variable and observe the effect on the dependent variable.
To be conclusive, other variables must be controlled, like the fabric and the amount of dirt of the t-shirts.
Explanation:
In an exothermic reaction, heat is released into the surroundings. In this type of reaction, energy of products is less than the energy of reactants.
In an endothermic reaction, heat is absorbed by the reactant molecules. In this type of reaction, energy of products is more than the energy of reactants.
Therefore, we can conclude that while performing an experiment involving a reaction between two chemicals, the scientist observes that the reaction container has become warm. The observation is an example of exothermic reaction.
Answer:
The earth rotates because of the way it was formed. Our Solar System formed about 4.6 billion years ago when a huge cloud of gas and dust started to collapse under its own gravity. As the cloud collapsed, it started to spin.
appellate jurisdiction
When a court has appellate jurisdiction, then it can hear a case once a lower court has ruled on it. Hence, option B is correct.
The ability of a higher court to consider appealing from a lower court is known as appellate jurisdiction. A higher court has the authority to reconsider rulings and alter their conclusions.
The highestcourt has judicial power over circuit courts, whereas the circuit courts have judicial power over the circuit courts in the federal judiciary. With appellate jurisdiction, the majority of higher courts only review the lower court's judgment to check for any legal mistakes.
The majority of cases that the Highest Court of States decides fall under its appellate authority. It can evaluate the majority of federal court rulings as well as state court rulings affecting constitutional or statutory law. In Article 3, Section 2 of the US Constitution, even the Supreme Court's appellate jurisdiction is discussed.
Therefore, it concludes that appellate jurisdiction is the correct answer.
