Firemen also need to know the water pressure that a hydrant holds. Each hydrant is unique. A hydrant’s water pressure varies. For a fireman, knowing the pressure of the hydrant, before attaching the hose, helps ensure that the correct pumping operation will work. A fire company can compensate for a low pressure using pumps on their fire engine.
Another type of boat is the vee bottom hull, and this is the most common out of all the boats. This boat offers a good ride in rough waters. It has a “V” shape that extends to the back of the boat; it usually flattens out until it all but all disappears at the transom. The surface at the bottom of the boat is called the pad. The hull on the boat is the water tight body of the ship.
Examples are the Red Cross, the RNLI and Mountain Rescue. The Red Cross Mountain Rescue The RNLI First Aid To save lives To save lves at sea Emergency responses To find/locate missing and stranded people Search and rescue missions Refugee services To co-ordinate search helicopters Flood rescue Protecting people in conflict To work alongside the RNLI and RAF Training people to be safe at sea Finding missing family Ensure beach
This helps with buoyancy and balance. When they breathe-only through their nostrils, they can exchange 90% of the air in their lungs with each breath, compared to a human who only exchanges about 10% of their air. They may need to breathe every 30 seconds during strenuous activity but can stay submerged for up to 20 minutes. Their muscles lack the density of myoglobin (muscle hemoglobin) that is typical of other diving mammals. This trait contributes to their relatively short (8-15 minute) and shallow (10-20 feet) dives compared to seals and dolphins, however they do swim like dolphins and seals in a dorsoventral fashion as opposed to side to
Running Head: AQUATIC THERAPY TECHNOLOGY Aquatic physical therapy and today’s technology name institutes name Aquatic physical therapy and today’s technology Aquatic Therapy is physical therapy in an aquatic environment by a physical therapist or a physical therapy assistant. It is designed to improve stability and flexibility among other things. There are several new devices in technology that help to achieve the goals a physical therapist is trying to reach with patients. An underwater treadmill, an underwater monitoring system, and a counter current pool, are all examples of this technology and ways computers help in the field of physical therapy. Aquatic therapy facts The physical properties of aquatics
3) Both you and your partner must kneel down as the experiment is best conducted on the floor 4) Decide on who will produce the waves first as both cannot be sending waves at the same time 5) For the first wave (longitudinal), one partner pushes the slinky towards the other partner, and repeatedly keeps doing so with constant force and motion, to produce the longitudinal wave. Your partner needs to be observing the strength of the wave as it passes back and forth. 6) Direction of wave travel Direction of wave travel For the second wave (transverse), the person producing the wave must move their hand left and right continuously with a constant force to produce the transverse wave. Hand movement perpendicular to the direction of the wave Hand movement perpendicular to the direction of the wave Spring moves side to side Spring moves side to side 7) Repeat steps 5 and 6, swapping roles 8) Each person decides which wave had the most force. (Hint: you should decide this upon how the wave displaced your hand as it hit your side of the slinky
Determination of “g” by the use of a Pendulum This experiment is going to utilize a bob on the end of a string line to determine the value of little “g” by measuring the length of the string and the duration of time it takes for the bob to swing from one fulcrum point back to the same point after swinging 10 times. The justification for the bob swinging 10 times is to generate a more accurate measurement of time. To start the supplies that are required for this experiment are a stable stand for the string to be secured to. A minimum of a two yard line of string to that can be secured to the anchor and a bob and obviously a bob to be attached to the end of the string. We also need a stopwatch to measure the time duration and a measuring tool to determine the length of each experiment.
The crew will also be asked to be loaded last because the crew will be essential in loading the lifeboats. Since the crew should have some sort of training for this sort of disaster, they will be crucial to maintaining a level of comfort for the passengers which will allow for the lifeboats to be loaded efficiently.
