Drag Force: A spherical particle of radius 5.9 cm and a mass of 229 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) The position of the particle is given by x (t) In (1 + bvot), where x is its position and t is the elapsed time. The initial speed vo is 17.4 m/s, and the constant b is 0.4 m-1. (b) What is the velocity of the particle after 2.9 seconds? (c) What is the acceleration of the particle after 2.9 seconds?

Given a cylindrical container with a small 0.2 cm diameter hole a distance of 2 cm from the bottom, devise a method for determining the velocity of the water that would flow out of the hole? You only have rulers and a stopwatch. Describe your method here. Sbiect

The heart of a resting adult pumps blood at a rate of 5.00 L/min. a. Convert this to cm^3/s.b. What is this rate in m^3/s?

About 32% of the body of a person floating in the Dead Sea will be above the water line. Assuming that the human body density is 0.978 g/cm³, find the density of the water in the Dead Sea. Number i Units Save for Later

Question 6: Suppose you have a coffee mug with a circular cross-section and vertical sides. What is its inside radius in cm if it holds 375 g of coffee when filled to a depth of 7.5 cm? Density of coffee is 1000 kg/m³. Unit conversion: 1 kg = 1000 g; 1 m = 100 cm.

An object has density ρoriginal�original. Suppose each of the object's three dimensions is increased by a factor of 2 without changing the object's mass. By what factor will the density change?

Drag Force: A spherical particle of radius 5.9 cm and a mass of 226 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) The position of the particle is given by x (t) 1 In (1+ bvot), where x is its position and t is the elapsed time. The initial speed vo is 27.8 m/s, and the constant b is 0.3 m-1. (b) What is the velocity of the particle after 3.3 seconds? (c) What is the acceleration of the particle after 3.3 seconds?
