Mindblown: a blog about philosophy.

Suppose the amount of liquid dispensed by a certain machine is uniformly distributed with lower limit A 8 oz and upper limit B 10 oz. Describe how you would carry out simulation experiments to compare the sampling distribution of the (sample) fourth spread for sample sizes n 5, 10, 20, and 30.

a. Only a handful of candidates run for office. b. All candidates who run for office have equal funding. c. Corporations and the wealthy cannot donate an excessive amount. d. Candidates focus on the day’s controversial issues. Answer:- c. Corporations and the wealthy cannot donate an excessive amount. Funding of party-political movements are controlled by law,…

Jupiter’s mass is 320 times that of the Earth and its radius is 11.2 times the Earth’s. The Earth’s surface gravitational field strength is 9.81Nkg−1. Calculate the gravitational field strength close to the surface of Jupiter

Mount Everest is approximately 9.0km high. Calculate how much less a mountaineer of mass 100kg (including backpack) would weigh at its summit, compared to her weight at sea level. Would this difference be measurable with bathroom scales?.

A stone of mass 0.20 kg is whirled round on the end of a string of length 30 cm. The string will break when the tension in it exceeds 8.0 N. Calculate the maximum speed at which the stone can be whirled without the string breaking.

Calculate how long it would take a ball to orbit the Earth once, just above the surface, at a speed of 7920 m s−1. (The radius of the Earth is 6400 km.)

A car is travelling along a flat road. Explain why it cannot go around a bend if the road surface is perfectly smooth. Suggest what might happen if the driver tries turning the steering wheel.

A spacecraft orbits the Earth in a circular path of radius 7000 km at a speed of 7800 m s−1. Determine its angular velocity

A car travels around a 90° bend in 15 s. The radius of the bend is 50 m. a. Determine the angular velocity of the car.               b. Determine the speed of the car.

The angular velocity of the second hand of a clock is 0.105 rad s−1. If the length of the hand is 1.8 cm, calculate the speed of the tip of the hand as it moves round.
