Question 3 2 pts K calculate the Using the formula for Hooke's spring, v = 4.1204...
using the formula P= K x V or P=K/V calculate the constant K pressure kPa=100.21 temperature = 24.0 oC someone answered that the answer is 4.17541 . but i want to know if that answer is in joules , cm ,L or something else ? can someone help like in complete answer so i know the step thx
2. Consider the following physical situation: A spring that obeys Hooke's Law and has a known/given spring constant k has been compressed to half of its equilibrium length. It's anchored at one end while the other end pushes (but is not attached to) a block of mass m in the horizontal direction. The block is initially held in place. Once released, the block accelerates to the right and achieves a final speed of ve at the point when it leaves...
Question 4 2 pts What is the electric potential, V, at a point that is r=0.66 m away from a positive point charge q = 8.3x10C? Take the electrostatic constant, k = 9.0 x 10°Nm²/C2. Please round your answer to the nearest whole number. Equation: V kg 7
Question 4 2 pts A spring of spring constant k 12.5 N/m is hung vertically. A 0.500 kg mass is then suspended from the spring. What is the displacement of the end of the spring due to the weight of the 0.500 kg mass? O 0.692 m O 0.039 m O 0.2 m O 0.392 nm
Problem 2. (6 pts: 2 + 2 + 2) A car oscillates vertically on a bumpy road as if it were a mass m = 400kg on a spring, with spring constant k = 4 x 10^N/m. The car is moving at a constant velocity v, and at time t, the equation of the road surface below the car is given by ut y(t) = to cos (10) a) Let X(t) be the upward displacement of the mass m from...

Question 12 4 pts Determine the molecular formula based on the structure listed here. The molecule has carbon atoms, hydrogen atoms, and oxygen atoms. Question 13 3 pts Benzoic acid has molecular formula of CyH,O2, calculate the molecular weight. For convenience, use the following values for mass of C, H, and O: C: 12 H: 1 O: 16 4 pts D Question 18 Identify formula and basic property of sodium carbonate. O Sodium carbonate which has the formula of NaOH...
Question 3 A spring of spring constant k is compressed by a distance d by a mass mi and released. This propels the mass down a flat track. Another spring, also of spring constant k, is on the other side. Another object of mass m is sitting in the middle of the track. The first mass strikes it and sticks to it. he entire track is frictionless, except for a small region of the track to the left of m2,...
Question 3: By using the indicated number of slices, calculate the approximate volume of the solid to 8 decimal places and record your results in the table below. The result for n - 4 is recorded, and the result for n 100 is given as well. The file in the "Projects" folder gives explicit instructions to set up the worksheet for n -4, and to check that you understand the procedure, make sure that your answer for n -100 matches...
