A hockey puck (5g) slides horizontally without friction across the ice from position A to E. Draw the energy bar graphs for each position.

State the number of significant digits and the implied precision of the given number. The number 1.928×10^4 has........ significant digits (type a whole number) B. What is the implied precision of the number 1.928×10^4 s? A. The number is precise to the nearest hundred seconds B. The number is precise to the nearest second. C. The number is precise to the nearest ten seconds

A heavy rainstorm dumps a total of 73 cm of rain on a rectangular shaped city area measuring 9 km by 17 km over a 27 hr period. Determine the average rate of rain fall in metric tons per second. NOTE: 1 cm3 water has a mass of 1 gram and 1 metric ton = 1000 kg. I attached how far I have gotten on this problem and I don't know if I did that correctly or not and am not sure where to go from where I am at.

The radius of an atom of gold (Au) is about 1.35 Å. How many gold atoms would have to be lined up to span 4.0 mm? Express your answer using two significant figures.

..................... The dimensions of the quantity kinetic energy, designated by K, are kg m/s, It can be written in terms of the momentum p and mass m as K = 2m (a) What are the units of momentum in terms of fundamental SI units? (Use the following as necessary: kg, m, and s.) [P) - (b) Force is measure in units of newtons, N, where 1N- 1 kg m/s. What are the units of momentum p in terms of a newton and another fundamental SI unit? (Use the. following as necessary: N, m, and s.) [P) = (c) What If? Physicists often measure the momentum of subatomic particles moving near the speed of light in units of MeV/c, where c is the speed of light, and 1 Mev = 1.6 x 101 kg m/s. Based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental SI units? What are the units of momentum for a high-speed subatomic particle in terms of a newton and another fundamental SI unit? [P] -

A rectangle has a length of (5.1 ± 0.2) m and a width of (2.3 ± 0.1) m. Calculate: (a) the area and (b) the perimeter of the rectangle, Give the uncertainty in each value.
