Your teacher gives you an envelope that contains the following items: ● 20 red paper circles labeled with a β€œ+” symbol to indicate they represent protons ● 20 blue paper circles with no label to indicate they represent neutrons ● 20 yellow paper circles labeled with the β€œ-β€œ symbol to indicate they represent electrons Your teacher then challenges you to use the items in the envelope to create a model of a carbon-14 atom. Before you begin, you and your group brainstorm ideas for creating your model. Your group suggests the following steps: Step Procedure 1 use 6 red circles for the nucleus of the atom 2 use 14 red circles for the nucleus of the atom 3 add 6 blue circles to the nucleus of the atom 4 add 8 blue circles to the nucleus of the atom 5 place 14 yellow circles around the nucleus of the atom 6 place 6 yellow circles around the nucleus of the atom Which of the following steps should you follow to create a correct model of a Carbon-14 atom? A. steps 2, 3, 6 B. steps 2, 4, 5 C. steps 1, 4, 6 D. steps 1, 3, 5

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0Β° above the horizontal. it then moves 127 ft at an angle of 46.0Β° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12Γ—10βˆ’6 kβˆ’1 and23Γ—10βˆ’6 kβˆ’1 respectively.
