Science and the scientific method are continually ongoing process because when new observations are discoveries are made which do do fit into the pattern of accepted scientific knowledge, the previously accepted knowledge must be tested once more for accuracy.

Explanation:

Science is a systematically organized body of knowledge that seeks to explain the universe around us through observation and experiment.

Science employs the scientific method in order to study, and explain the natural world.

The scientific method involves the following steps:

Observation, Hypothesis, Prediction, Hypothesis testing, Analysis, Conclusion.

Observation involves paying attention to a particular phenomena around us and then asking questions.

Hypothesis refers to intelligent guesses based on the observed events

Prediction involves predicting phenomena based on the hypothesis made.

Hypothesis testing involves careful design of experiments to test the validity of the hypothesis made.

The results of the experiments are then analyzed and evaluated in the light of the original hypothesis.

Conclusions are then made to either, accept, reject or modify the hypothesis based on the results of the experiments.

During the course of these processes, new observations can be made which are not in agreement with previous accepted knowledge, therefore, new hypothesis and experiments must be made. Also, with advancement in technology, new insights are gotten from experiments and observations which previously was not available, all these contribute to ensuring that science and the scientific method are a continually ongoing process.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge, $v = \dfrac{e_p}{q}$ then the following gives us the potential difference, $\delta v = v_b - v_a$ $\begin{aligned} \delta v & = \dfrac{e_p_b}{q} - \dfrac{e_p_a}{q} \\ & = \dfrac{\delta e_p}{q} \end{aligned}$ the formula $\delta v = \delta e_p / q$ may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get $\delta e_p = q\delta v$ using q = 8.00 × 10⁻¹⁹ c and δv = 2.00 v, we get $\begin{aligned} \delta e_p & = (8.00\times10^{-19} \text{ c})(2.00\text{ v}) \\ & = 1.60\times 10^{-18}\text{ j} \end{aligned}$ the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
