Answer:

their distance and displacment are both 400 meters. and No distance and displacement are not equal for a person who runs 2.5 times a circular track.

Explanation:

if you run in a ircle you are coming back to the starting poing ad remember distane is the total length travlled while displacement is the final- initial length

Answer:

1,803,036.67 W

Explanation:

Data provided in the question:

People per hour that can be moved by lift = 49800

Height of movement, h = 190 m

Average mass per person = 70 kg

Now,

Power = Rate of doing work

Thus,

Power = ΔU

= mgh

here,

m = total mass

g = acceleration due to gravity

or

Power =  (70kg × 49800)(9.8)(190)

or

Power = 6,490,932,000 J per hour

also,

Watt = Joule/second

Therefore,

Power = 6,490,932,000 ÷ 3600

= 1803036.67 W

Final answer:

To estimate the maximum total power needed for Squaw Valley ski area to move 49800 people per hour on their lifts, we calculate the work done per person per hour and then divide it by the time taken to travel vertically by 190 m. The estimated maximum total power needed is 3.31 x 10^8 W.

Explanation:

To estimate the maximum total power needed to move 49800 people per hour on a skilift at Squaw Valley, we can calculate the work done per person per hour and then divide it by the time taken to travel vertically by 190m. The work done is equal to the potential energy gained, which is given by the formula mgh, where m is the average mass per person (70 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the vertical height gained (190 m). Multiplying this by the number of people per hour gives us the total work done per hour. Dividing this by the time taken to travel the vertical height gives us the maximum power needed. The power is given by the formula P = W/t, where W is the work done and t is the time taken.

Using the given values, we have:

Work done per person per hour: (70 kg) x (9.8 m/s^2) x (190 m) = 128660 J

Total work done per hour: 128660 J x 49800 = 6.40 x 10^9 J

Time taken to travel vertically by 190m: 190 m / (9.8 m/s^2) = 19.39 s

Maximum power needed: (6.40 x 10^9 J) / (19.39 s) = 3.31 x 10^8 W

Answer : As the pressure on a sample of gas increases, the volume of the sample decreases.

Explanation :

According to the Boyle's, law, the pressure of the gas is inversely proportional to the volume of gas at constant temperature and moles of gas.

    (At constant temperature and moles of gas)

From the we conclude that the higher the pressure of gas, lower will be the volume and lower the pressure of gas, higher will be the volume of gas.

Hence, as the pressure on a sample of gas increases, the volume of the sample decreases.

Answer:

The correct answer is D.

D:The surface of the coating allows light from the room to pass through but blocks the light from the screen.

Explanation:

Glare is produced on a computer screen when light from some external source reflects on the screen.

Anti-glare coating do not absorb light to reduce glare but they actually reduce glare by encouraging the light from the room to pass through the screen so that less light is reflected. Polarized lenses absorbs light to reduce glare, not anti-glare coating.

Answer: d
