The men's world record for swimming 1500.0 m in a long course pool (as of 2007) is 14 min 34.56 s. At this rate, how many second
vesna_86 [32]

Answer:

It will take 140.76 seconds to swim 0.150 miles.

Explanation:

Distance covered by man by swimming for t time= d

d = 1500.0 miles

t = 14 minutes + 34.56 seconds

1 min = 60 seconds

t = 14 × 60 seconds + 34.56 seconds = 874.56 seconds

Speed of the man while swimming = S = \frac{1500.0 m}{874.56 s}=1.715 m/s

If the man swims 0.150 miles with the same speed ,then the time taken by him be T.

0.150 miles = 0.150 × 1609.34 m = 241.401 m

(1 mile= 1609.34 meters)

S=\frac{Distance}{time}=\frac{241.401 m}{T}

1.715 m/s=\frac{241.401 m}{T}

T = 140.76 seconds

It will take 140.76 seconds to swim 0.150 miles.

What happens when liquid changes to gas?
Nady [450]

Answer:

#1

The temperature that this happens is called the freezing point and is the same temperature as the melting point. As more energy is put into the system, the water heats up, the molecules begin moving faster and faster until there is finally enough energy in the system to totally overcome the attractive forces.

Explanation:

#2

Heating a liquid increases the speed of the molecules. An increase in the speed of the molecules competes with the attraction between molecules and causes molecules to move a little further apart. ... A decrease in the speed of the molecules allows the attractions between molecules to bring them a little closer together.

Describe the direction of the wind movement around the center of high air pressure
Artemon [7]

The coriolis force caused by the Earth's rotation is what gives winds within high-pressure systems their clockwise circulation in the northern hemisphere (as the wind moves outward and is deflected right from the center of high pressure) and counterclockwise circulation in the southern hemisphere (as the wind moves ...

what pressure will be needed to reduce the volume of 77.4 l of helium at 98.0 kpa to a volume of 60.0 l? 76 kpa 126 kpa
nekit [7.7K]
The system follow the Boyle's Law:

P_1\cdot V_1 = P_2\cdot V_2\ \to\ P_2 = \frac{P_1\cdot V_1}{V_2} = \frac{98\ kPa\cdot 77.4\ L}{60.0\ L} = \bf 126.4\ kPa
