Object X is negatively charged and is repelled by object Y, meaning Y must also be negatively charged. Object Z is attracted to object Y. Since Y is negative, Z could be positively charged (opposite charges attract) or neutral (neutral ...

The charge of one electron is − 1.6 × 10−¹⁹ C. The object gains 5.0 × 10¹⁸ electrons, resulting in a charge change of: q = (5.0 × 10¹⁸) × (−1.6×10⁻¹⁹) = −0.80C Net charge = 1C−0.80C= +0.20C. Correct answer: ...
Powers in mathematics represent repeated multiplication of a number by itself. The base is the number being multiplied and the exponent shows how many times it is multiplied. For example 2³ means 2 multiplied by itself three times (2 * ...
The probability of an event is a measure of the likelihood that the event will occur. It is calculated as the ratio of favorable outcomes to total possible outcomes. Probability values range from 0 (impossible event) to 1 (certain event). ...
P(A) = 4/5 and P(A ∩ B) = 7/10, this means the probability of event A occurring is 4/5, and the probability of both events A and B occurring together is 7/10. To find P(B), use the formula P(A ∩ ...
