Three small charged spheres are at the corners of an equilateral triangle of sides 40 cm. Spheres 1 and 2 are fixed in place and have charges $q_1 = q_2 = 20\mu C$. Sphere 3 is tied to a string (shown in black) and has a mass of 3.0 kg and a charge $q_3 = 40\mu C$. Calculate the tension in the string.

In the space surrounding Earth, the main component of the planet's magnetic field is the field due to a magnetic dipole. Part A In what direction is Earth's magnetic dipole moment? Earth's magnetic dipole moment points toward the North Pole. Earth's magnetic dipole moment spins in the plane of the equator. Earth's magnetic dipole moment points from the point at the equator that has the longitude 180 ∘ to the the point at the equator that has the longitude 0 ∘ . Earth's magnetic dipole moment points toward the South Pole. Earth's magnetic dipole moment spins in the plane that contains lines of the longitude 0 ∘ and 180 ∘ . Earth's magnetic dipole moment points from the point at the equator that has the longitude 0 ∘ to the the point at the equator that has the longitude 180 ∘ .

On March 17, Advanced Technologies developed a patent related to laser surgery techniques. They spent $1,300,000 to develop the patent internally, consisting of personnel ($850,000), equipment ($330,000), and materials ($120,000). The company also had the following additional costs: $30,000 in legal fees associated with the purchase and filing of the patent, $45,000 to advertise its new laser surgery techniques, and $55,000 to train employees. What is the recorded cost of the patent? Total capitalized cost

Question: Design and implement a 4-bit serial adder/subtractor using shift registers (refer to lab 6). The circuit should be able to do both addition and subtraction with following requirement: 2. The circuit should have a control "addsub" signal, and 4-bit binary inputs "a" and "b" representing number from 0 - 15: a. When addsub = 0, circuit will do addition "a + b" b. When addsub = 1, circuit will do subtraction "a - b" 3. You can assume "a" is always larger than "b", so result is always positive 4. To get all credits, you need to load binary-coded decimal (not 2's compliment) into shift register directly. If you load 2's compliment into shift register, it's only considered partially correct even if the circuit works properly.

A model maker wants to make two sets of traffic lights for a crossroad. The required sequence is shown in Figure Q11. A 4-bit binary modulo-10 counter is available. Its outputs are A, B, C, and D with A being the most significant. When the counter is zero, the sequence is in state 0, and Set 1 has the red light on and Set 2 has the green light on. Each decimal state is to be represented by its equivalent natural binary code.

A light on is indicated by a 1 in the truth table and a light off by 0. Counts above 9 are not used and you should enter these in the truth table as don't care states. In your answer sheets, show the completed columns for A1 and R2. You should also show the columns of A, B, C, and D. (4 marks) (q) Write out a sum-of-minterms for G2, treating don't care states as 0.
