Nitrogen dioxide (NO) is produced from the reaction between Ny and 0,, How many moles of N, are needed to produce s moles of NO2
O A 2 mol
0 2.5 mol
6. I mol
D. 5.5 mol

How would doubling the made of an object change the objects potential energy

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
