Any baseball fans out there that are good at physics?
A baseball is hit nearly straight up into the air with a speed of 20 m s.a How high does it go?b How long is it in the air?
Chemistry fans - what's the best way to gently clear a shower drain ?
We have old pipes in our house. I am concerned that drain cleaner will eventually destroy our pipes. I have been told to use two different methods to clear and maintain a shower drain. One spoon in baking soda into the drain and then pour in some vinegar OR 2 just pour a bottle of bleach down the drain and let it sit over night. My question is this given that baking soda is slightly basic, while vinegar is slightly acidic, wont the vinegar baking soda mix just neutralize each other ? Would bleach, with a pH of 13, be better?
Why tabel fans runs in clockwise direction and ceiling fan anticlockwise direction?
Using AC microwave fans to generate energy?
How Do I combine several AC fans, that I removed from old microwaves together to generate more electricity? can I simply wire the alike wires together? my other question is other than using a multimeter is there something I can purchase that will tell me how much voltage is currently being made, and lastly is it as simple as wiring an outlet into these fans to plug into?Ok so how about if I use AC stepper motors?
What direction should my paddle fans turn to circulate warm air down ? clock or counter clock?
Fan Carts Physics Problem?
Two fan carts labeled A and B are placed on opposite sides of a table with their fanspointed in the same direction, as shown. Cart A is weighted with iron bars so itis twice as heavy as cart B. When the fans are turned on, they provide a constantforce on the cart independent of its mass. Assume that friction is small enough to beneglected. The fans are set with a time so that after they are switched on, they stayon for a fixed length of time, t, and then go off. a Just after the fans go off, which of the following statements are true about themomenta of the two carts?i. pA > pBii. pA pBiii. pA < pB b Just after the fans go off, which of the following statements is true about thekinetic energies of the two carts?i. KA > KBii. KA KBiii. KA < KB c Which of the following statements is true? You may choose as many as you like,or none. If you choose none, specify this.i. After the fan is turned on, each cart moves at a constant velocity, but thetwo velocities are different from each other.ii. The kinetic energy of each cart is conserved.iii. The momentum of each cart is conserved.
Where can I find a fan meeting theses specs.?
CFM of 169 180 CFM, CFM of 150 if need bePa 50 to 120Fan that operates at 12voltsI have checked many sites but none selll a fan meeting these spec.s. The one place that did only sell fans in bulk. I only need 1.
What do I need to make a small 5vdc fan variable speed?
Fan 5VCD 0.4 wattsPower 9volt or 4AAASetup might be 2 fans and 1 9voltSetup might be 1 fan and 1 9voltSetup might be 2 fans and 4AAASetup might be 1 fan and 4AAAThe Fan is 0.4 wattsVery small 20mm fan
Is there any major difference between the action of exhaust fan and centrifugal pump?
