To test paint quality, scientists designed an experiment where the paint was exposed to temperatures ranging from 260 degrees Ce

pishuonlain [190]

Answer:

The independent variable is the temperature to which the paint and materials are exposed

The dependent variable is the presence of peeling and cracking of the paint

The constant rates are the paint and material used for each trial

Explanation:

The treatment the to which the paint is subjected = Temperatures from 260 °C to 650 °C

The method of determining the paint quality = By peeling and cracking

The types of paint and materials used = The same paint and material

The independent variable is the variable suspected as the cause of the effect being studied. It is the variable introduced as a treatment

In the question, given that the paint is subjected to different temperatures from between 260°C to 650 °C, the temperature changes introduced is the independent variable

Therefore;

The independent variable = The temperature to which the paint and materials are exposed to

The dependent variable is the effect variable. It is the variable of the property being investigated and it is also the variable that is measured in the investigation

In the question, given that the after heating the paint and material, the scientist check for peeling and cracking, the dependent variable is the occurrence of cracking and peeling at a given temperature

Therefore;

The dependent variable = The presence of peeling and cracking of the paint

The constant rate(s) are variables which are kept constant during the investigation, under the different treatments

The constant rate(s) in the tests are the paint and material, which were kept the same for each trial to reduce the effect of underlying factors that may impact on the result and obscure the relationship between the dependent and independent variables

Therefore;

The constant rate are the paint and material used for each trial

What is/are the possiable products of dehydrohalogentaion of cis-1-bromo-2-ethylcyclohexane?

STALIN [3.7K]

what is Maximum possible products?

Although Minimum Viable Product strategies are effective for startups, they presuppose you have no limitations. However, in an MPP universe, your limitations serve to focus you rather than to thwart you. Instead than conceptualizing ideas for the future, they require you to consider how well you can meet your clients' wants inside a specific situation that now exists.

Photobox will introduce countless new product lines that are only modifications of current products. For instance, a bowl could be printed as a dog bowl or a cereal dish for kids. The tech stack doesn't need to be altered, and customization yields the highest return on investment for the product.
