Answer:
In the grapher: The stops are marked with a flat line, velocity with a diagonal line, and acceleration with a curve.
Average speed= Total distance/Total time
Explanation:
Answer: The scientists should form a hypothesis and design an experiment.
To form a scientific theory and law, the first step is always to formulate a question based on some observation. The n next step is to formulate a hypothesis and then an experiment is designed. The experiment is conducted and the data is collected and recorded. The, conclusions are drawn and results are communicated.
Hence, the next step after formulation of a question based on an observation, the scientist should form a hypothesis and design an experiment.
1.) Its a controlled experiment because both groups A and B get the equal mount of sunlight and water. The manipulated variable would be the fertilizer.
2.) Because a theory must consists of more than experiment before it can actually be considered a theory. It must be performed multiple times.
3.) Because if the growth was on the B spot, the graph would be a bar graph because the growth would still increase by each day.
Given Information:
Electric field = E = 180,000 N/C
Distance = r = 1.50 cm = 0.015 m
Required Information:
Charge = q = ?
Answer:
charge = q = 4.5x10⁻⁹ C
Explanation:
The electric field is given by
E = kq/r²
Where k is the coulomb constant k = 9x10⁹ Nm²/C²
q = Er²/k
q = 180,000*(0.015)²/9x10⁹
q = 4.5x10⁻⁹ C
Therefore, the charge is 4.5 nC
