- When an object with an electric charge of −0.070mC is 2.0m from an object with an electric charge of −0.010mC , the force between them has a strength of 1.573N . Calculate the strength of the force between the two objects if they are 0.67m apart. Round your answer to 2 significant digits.How many kw-hr of energy does a 40 Watt light bulb use in one hour? B) FPL charges 10.8 cents per kw-hr of energy usage. How much did you spend running your 40 Watt light bulb for one hour?In the process of using the scientific method, a researcher: O Directly tests both the null and alternative hypotheses. O Directly tests only the alternative hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because this is the hypothesis of interest. O Directly tests only the null hypothesis because the null hypothesis leads to a specific prediction that can be compared with data. O Can not directly test either hypothesis.
