While he's in the air, the reaction force is air resistance and when he's in the water the reaction force is upthrust. Hope this helps.
The most usual downward force is the force of gravity; the weight of an object exerts force in a downward direction. There are also other forces which can be exerted in that direction. If you wanted to, you could fire a gun in a downward direction, in which case the explosive force of the gun is added to the force of gravity.
Nuclear is the answer
The force that holds water in the container is called centripetal force. It is not specific to water, it affect anything spun in a circle. The water has inertia, which means it wants to continue in the direction that its moving - if you were to let go, the water would fly forward in its current direction. And not only does your container keep the water from flying off, it also keeps changing the direction the water wants to go. If you spin the container fast enough, centripetal force can beat the force of gravity. Its as if the water is being endlessly thrown into the bottom of the container.
Turn off your phone, take off the back and take out the battery. look in the area where the battery sits for a small square sticker. if its white there is no water damage, if the sticker is pink or red the phone has suffered water damage.
That depends on the design of the valve.
air in the water lines causes banging and whistles/screams. Turn off main water, turn on the faucet, turn main water back on, and it should force the air out.
This product has an auto shut-off for added safety. The kettle automatically turns off after water boils for added safety & convenience
So you can turn it on... and you can turn it off...!
no you dont It is safe to leave the water on, whislt changing the stem If you don't want any problems, turn the pressure off.
Yes, you should turn it off.
yes turn the water off and get someone to help you put in the water faucet
Turn off to replace or service. Turn off if away from home for extended amount of time, such as vacation.
no
When washing dishes, turn off water when using soap. Also you can turn off water while brushing teeth, when you rinse, then you can uses the water.
shutting off the valve
Yes, make sure you turn off power to the water heater. Also shut off the icemaker. No. Just turn it off. Just remember to turn it back on before you open any of your inside faucets. And you also need to turn off the hot water heater.
