How long does it take for a person that is walking at 2 meters per second to travel 1200 meters

Physics
1 answer:
Zanzabum1 year ago
5 0

The time taken by a person that is walking at 2 meters per second to travel 1200 meters is 600 s

v = d / t

v = Velocity

d = Distance

t = Time

v = 2 m / s

d = 1200 m

t = d / v

t = 1200 / 2

t = 600 s

Velocity is the rate of change of distance with respect to time. It is denoted using V. Its unit is usually m / s.

Therefore, the time taken by thy person is 600 seconds

A scientist reports a measurement of the temperature of the surface of a newly discovered planet as negative 20 Kelvin. What con
jarptica [38.1K]

Answer:

The temperature of this newly discovered planet violates the third law of thermodynamic, there is a mistake in this value.

Explanation:

The third law of the Thermodynamic says:

<u> At zero kelvin all molecular movement stops, which means that the entropy will be zero at this temperature.</u>

So we can say there is no thermodynamic system that has temperature values less than 0 K.

The conclusion of the report will be.

The temperature of this new planet violates the third law of thermodynamic, there is a mistake in this value.

I hope it helps you!

A student drops a ball from the top of a tall building; it takes 2.9 s for the ball to reach the ground.
AlexFokin [52]

<h2><u>We have</u>,</h2>

  • Initial velocity (u) = 0 m/s
  • Time taken (t) = 2.9s
  • Acceleration due to gravity (g) = + 10 m/s² [Down]

<h2><u>To calculate</u>,</h2>

  • Final velocity (v)
  • Height (h)

<h2><u>Solution</u><u>,</u></h2>

→ v = u + gt

→ v = 0 + 10(2.9)

→ v = 29 m/s \qquad … ( Ans )

And,

→ h = ut + ½gt²

→ h = 0(2.9) + ½ × 10 × (2.9)²

→ h = 5 × 8.41

→ h = 42.05 m \qquad … ( Ans )
