Question A charge of 50 nC is uniformly distributed along the y axis from y = 3.0 m to y = 5.0 m. What is the magnitude of the electric field at the origin? 30 N/C 15 N/C 90 N/C 18 N/C 50 N/C

The axle of a wheel is mounted on supports that rest on a rotating turntable as shown in the figure. (Figure 1) The wheel has angular velocity ω1ω1omega_1 = 46.5 rad/s about its axle, and the turntable has angular velocity ω2ω2omega_2 = 34.0 rad/s about a vertical axis. (Note arrows showing these motions in the figure.) Take the z-axis vertically upward and the direction of the axle at the moment shown to be the x-axis pointing to the right. Take the direction perpendicular to that of the axle at the moment shown to be the y-axis pointing in the page.What are the directions of ω1 at the instant shown?Express your answer with the appropriate units.  Theta1=? What are the directions of ω2 at the instant shown?Express your answer with the appropriate units.  Theta2=?

Lael wants to determine several totals and averages for active students.In cell Q8, enter a formula using the COUNTIF function and structured references to count the number of students who have been elected to offices in student organizations.

A solid sphere of radius 40 cm has a total positive charge of 26 μC uniformly distributed throughout its volume. Calculate the magnitude of the electric field (a) 0 cm, (b) 10 cm, (C) 40 cm and (d) 60 cm from the center of the sphere.

The weights of a certain brand of candies are normally distributed with a mean weight of 0.8602 g and a standard deviation of 0.0521 g. A sample of these candies came from a package containing 456 candies, and the package label stated that the net weight is 389.2 g.​ (If every package has 456 ​candies, the mean weight of the candies must exceed 389.2 / 456 =0.8534 g for the net contents to weigh at least 389.2 ​g.) a. If 1 candy is randomly​ selected, find the probability that it weighs more than 0.8534 g.

Question 7 of 9 (1 point) | Attempt 1 of Unlimited View question in a popup 6.2 Section Exercise 23 (calc TV sets: According to the Nielsen Company, the mean number of TV sets in a U.S. household in 2013 was 2.24. Assume the standard deviation is 1.4. A sample of 80 households is drawn. Part 1 of 5 B (a) What is the probability that the sample mean number of TV sets is greater than 2? Round your answer to at least four decimal places. இ The probability that the sample mean number of TV sets is greater than 2 is 0.9370 ol. Part 2 of 5 (b) What is the probability that the sample mean number of TV sets is between 2.5 and 3? Round your answer to at least four decimal places. The probability that the sample mean number of TV sets is between 2.5 and 3 is 0.0483 Part 3 of 5 (c) Find the 40th percentile of the sample mean. Round the answer to at least two decimal places. The 40th percentile of the sample mean is 2.20 Part: 3/5 Part 4 of 5 (d) Would it be unusual for the sample mean to be less than 2? Round your answer to at least four decimal places. It is unusual because the probability of the sample mean being less than 2 is Х 5
