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.

Answer: The answer to the question "what works all the time but never sleeps" can vary depending on the context or interpretation. Here are a few possible answers:
Explanation:
1. A machine or technology: Machines such as computers, servers, or automated systems can work continuously without needing sleep. They can perform tasks, process information, or operate machinery 24/7.
2. The human brain: While humans do need sleep for rest and rejuvenation, the brain never stops working. Even during sleep, the brain continues to regulate bodily functions, process information, and even dream.
3. Nature: The natural world is constantly active and functioning. For example, plants continue to photosynthesize, animals continue to move and hunt, and ecosystems continue to interact and evolve, even during the night.
4. Time: Time is always progressing and never stops. The concept of time keeps working, and events and processes occur continuously, regardless of day or night.
These are just a few possible answers. The correct response may depend on the specific context or intended interpretation of the question.
Answer: A man
Explanation:
A man works all day and never gets the chance to sleep.
Light takes 162.1 seconds to travel from Venus to earth.
Explanation:
Speed of light=3 x 10⁸ m/s
distance between Venus and earth =30,220,000 miles=48634375680 m
Now the distance is given by d= v t
d= distance
v= velocity
t= time
48634375680= 3 x 10⁸ t
t=162.1 s
