Andrea has a particularly old bike, and she has not lubricated the chain or gears. This causes friction inside the gears as she rides. She begins coasting on flat ground at a speed of 10 m/s, and after a few seconds is only going 8 m/s. How much energy has been converted to heat?
In one year, 15 dance studios opened in Durban. During that same year, SABC started broadcasting professional dance shows on TV, which sparked more interest in the sport. What would we expect to happen to the price and quantity of attending a dance lesson in Durban during that year?
Y=0.3sin(0.5x-50t). what is the maximum displacement of the particles from the equilibrium portion
A piano wire 0.5m longlong has a total mass of 0.01kg and is stretched with a tension ofof 800N. calculate the tension of the wire when it sounds it's fundamental note.
A hiker travels 4,5 km in a direction 12 degrees south of west and then 7,2 km in a direction 23 degrees west of south.
Determine the hiker’s overall displacement.
Draw each of the hiker’s individual displacement vectors on the same set of Cartesian axes, so that their initial points coincide at
PET has a Young's, Modulus of 3.5 GPa and PLGA 1.2 GPa. A polymer blend is prepared with 45:55 mixture (PET:PlGA) . What is the Young's, Modulus of this blend (use mixture rule). Calculate the percent load borne by PET when the blend is subjected to a load. If after 10 days, entire PET had degraded, what is the Young's Modulus of this blend.
what organism does not have any of the distinguishing characterists
Why is amount of reactant(s) measured in molarity?
What happened to the number of moles in a sample that originally occupied 500 mL with 2.50 moles and then occupied 750 mL?
Suppose that you have a computer with a memory unit of 24 bits per word. In this computer, the assembly program’s instruction set consists of 198 different operations.
All instructions have an operation code part (opcode) and an address part (allowing for only one address).
Each instruction is stored in one word of memory.
a. How many bits are needed for the opcode?
b. How many bits are left for the address part of the instruction?
c. How many additional instructions could be added to this instruction set without exceeding the assigned number of bits? Discuss and show your calculations.
d. What is the largest unsigned binary number that the address can hold?
