Write a program to calculate the sum of the following series:
1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 + ... + 1/20A tiny 0.8g ball carries a charge of magnitude 10μC. It is suspended by a thread in a
downward 500N/C electric field. What is the tension in the thread if the charge on the ball is
positive?
According to a study conducted by grade 11 students, Php155 is the monthly expense for cellphone loads of high school students on their province. A statistics students claims that this amount has increased since January of this year. Do you think his claim is acceptable if a random sample of 50 students has an average monthly expense of Php165 on cellphone loads? Using 0.05 level of significance, assume that a population standard deviation of Php52.
