How much force was used to move a box 42m if 13,734 J of work was done on it?
What is the angular momentum of a figure skater spinning at 4.4 with arms in close to her body, assuming her to be a uniform cylinder with a height of 1.6 , a radius of 15 , and a mass of 53 ?
A class of 11 students taking an exam has a power output per student of 122 W. Assume that the initial temperature of the room is 18.8oC and that its dimensions are 6.40 m by 14.5 m by 3.50 m. What is the temperature (in oC, do not enter units) of the room at the end of 54.0 m...
If a water heater has a capacity of 54.4 gallons and a 4910 W heating element, how much time is required to raise the temperature of the water from 19.8oC to 60.0oC? Assume that the heater is well insulated and no water is withdrawn from the tank during this time.
Sorry, rotational inertia I = 6.4 * 10^-3 kg*m^2. I really am stuck on this, can't figure out how to use angular momentum/torque relations to connect the dots and be able to solve for what they're asking ;\.
A gyroscope with rotational inertia 6.4 10-3 kg·m2 is precessing in a horizontal plane at 0.46 rad/s under the influence of a 0.31 N·m torque caused by a force pointing vertically downward. How fast is the gyroscope spinning on its axis?
I don't think this makes sense... there are not any oxygens on the left so Im pretty sure it doesn't work, unless you just add oxygen to the left im not sure you can do that though... If so it would look like this KNO3 --> KNO3 + O ^add O to this side as well Once a...
