Sample Response: I disagree with him because the angle of incidence is the angle between the incoming ray and the normal. The normal is perpendicular to the surface of the mirror.

this is the answer for edginuity and the other person was wrong

Kipish [7]

Answer:

When providing antibiotics to cows, it provides unspecified chemicals that can range to many different issues. These chemicals can both affect the cow and its produce. Asserting the fact into yogurt, this antibiotic(dependant on its chemical) can affect the product within both positive and negative ways.

What part of the scientific method do you decide if your hypothesis was right?
Harrizon [31]

Answer:

OBSERVATION is first step, so that you know how you want to go about your research. HYPOTHESIS is the answer you think you'll find. PREDICTION is your specific belief about the scientific idea: If my hypothesis is true, then I predict we will discover this. CONCLUSION is the answer that the experiment gives.

The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries). It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises.

1 Make an observation.

2 Ask a question.

3 Propose a hypothesis.

4 Make predictions.

5 Test the predictions.

6 Iterate.

OlgaM077 [116]

Answer:

Option D = 3.4 g/mL

Explanation:

Given data:

Volume of water = 21.2 mL

Volume of water + object = 27.8 mL

Mass of object = 22.4 g

Density of object = ?

Solution:

First of all we will calculate the volume of object.

Volume of object = Volume of water+ object - volume of water

Volume of object = 27.8 mL - 21.2 mL

Volume of object = 6.6 mL

Density of object:

d = m/v

d = 22.4 g/ 6.6 mL

d = 3.4 g/mL
