Suppose a +5 µC is fixed to a wall 20 cm to the immediate left of a 6 kg object that has a net charge of +10 µC charge that is tied to the wall by a string. Calculate all the forces acting on the object and the angle that the string makes with the wall.
The dimension of the work unit is: N/m kg*(m^(2))/(s^(2)) kg*(m^(2))/(s) The dimension of the work unit is: N/m kg$\cdot$m²/s² kg$\cdot$m²/s
The amount of meat in prehistoric diets can be determined by measuring the ratio of the isotopes nitrogen-15 to nitrogen-14 in bone from human remains. Carnivores concentrate $^{15}N$, so this ratio tells archaeologists how much meat was consumed by ancient people. Suppose you use a velocity selector to obtain singly ionized (missing one electron) nitrogen atoms of speed 8.50 km/s and bend them along a semicircle within a uniform magnetic field. The $^{14}N$ atoms travel along a semicircle with a diameter of 27.7 cm. The measured masses of these isotopes are $2.32 \times 10^{-26}$ kg ($^{14}N$) and $2.49 \times 10^{-26}$ kg ($^{15}N$). Find the separation of the $^{14}N$ and $^{15}N$ isotopes at the detector. Express your answer with the appropriate units. s = 3.16 cm Incorrect; Try Again; 4 attempts remaining

14. How many calories will it take to heat 200.0g of water from 23°C to its boiling point, 100°C? 5. A balloon is filled with 500.0 mL of helium at a temperature of 37°C and 755 mmHg. As the balloon rises in the atmosphere, the pressure and temperature drop. What volume will it have when it reaches an altitude where the temperature is -43°C and the pressure is 0.60 atm? Draw the Lewis Dot structure for NF3. F | F - N - F
