Answer: The correct statement order from the earliest to the most recent is (US satellite Explorer launched, NASA was established, first man orbited the Earth, first man walked on the moon.)

Explanation:

The United States first Satellite was launched in the date of February 1, 1958. It was given the name 'Explorer 1'. It was a cosmic ray detector which was constructed to measure the radiation environment in earth orbit.

NASA (National Aeronautics and Space Administration) was established in the year 1958 on the first day of October by United States of America. This was created as a response to the Soviet Union over thier first Satellite launch.

First man orbited the earth in the year 1961 on April 12. This was achieved by a Soviet Cosmonaut Yuri Alekseyevich Gagarin.

The first human on the moon is Neil Armstrong through the spacecrafts called Apollo's 11. This event occurred on 20 July 1969

The pressure at the bottom of a full barrel of water is Poriginal . Determine what happens to the pressure when the radius or he
Sholpan [36]

Answer:

a)   P' = P_original, b)  P ’= P_original + ρ  g Δh

Explanation:

The expression for nanometric pressure is

          P = ρ g h

where ρ  is the density of the liquid and h is the height

a) we change the radius of the barrel, but keeping the same height

as the pressure does not depend on the radius it remains the same

        P' = P_original

b) We change the barrel height

         h ’≠ h

we substitute in the equation

      P ’= ρ  g h’

      h ’= h + Δh

      P ’= ρ  g (h + Δh)

      P ’= (ρ  g h) + ρ  g Δh

      P ’= P_original + ΔP

In this case, the pressure changes due to the new height,

*if it is higher than the initial one, the pressure increases

*if the height is less than the initial one, the pressure is less

fiasKO [112]

Answer:

|F| = 393750  N

Explanation:

Given that,

Total mass of the train, m = 750000 kg

Initial speed, u = 84 m/s

Final speed, v = 42 m/s

Time, t = 80 s

We need to find the net force acting on the train. The formula for force is given by :

F = ma

F=\dfrac{m(v-u)}{t}\\\\F=\dfrac{750000\times (42-84)}{80}\\\\F=-393750\ N

So, the magnitude of net force is 393750  N.
