Answer:

a)    h = 1990 m, b) the height we can reach increases , c)  h = 2,329 m

Explanation:

.a) For this fluid mechanics problem let's use the pressure ratio

        P = P₀ + ρ g y

        P-P₀ = ρ g y

Where rho is the fluid density where it is contained, P₀ is the atmospheric pressure.

It does not indicate that the maximum pressure change before exporting is

             ΔP = 2.32 * (0.1 P₀)

Let's look for this pressure

            ΔP = 2.32   0.1    1.01 10⁵

            ΔP = 0.234 10⁵ Pa.

This is the maximum pressure difference, let's look for the height where we reach this value, the container has an internal pressure of 2.02 10 Pa, which we must subtract from the initial difference

            ΔP = ΔP - 2.02 10⁰ = 0.234 10⁵5 - 2.02

            ΔP = 23398 Pa

            ΔP = ρ g h

            h = ΔP /ρ g

            h = 23398 /1.20 9.8

            h = 1990 m

b) If air density decreases the height from 1,225 at sea level to 0.3629 to 11000m, the height we can reach increases

Density must be functioned with height

c) Now we introduce the contain in the ocean, the density of sea water is

            ρ = 1025 kg / m³

            h = 23398 / 1025 9.8

            h = 2,329 m

A person in the back of a pick-up moving at 20 m/s relative to the Earth, throws a baseball with a speed of 15 m/s in a directio
Bumek [7]

Answer:

This is known as a Galilean transformation where

V' = V - U

Where the primed frame is the Earth frame and the unprimed frame is the frame moving with respect to the moving frame

V - speed of object in the unprimed frame

U - speed of primed frame with respect to the unprimed frame

Here we have:

V = -15 m/s        speed of ball in the moving frame (the truck)

U =  -20 m/s        speed of primed (rest) frame with respect to moving frame

So  V' = -15 - (-20) = 5 m/s

It may help if you draw a vector representing the moving frame and then add

a vector representing the speed of the ball in the moving frame.

A 10 kg mass rests on a table. What acceleration will be generated when a force of 5 N is applied? a 0.5 m/s2 b 3.5 m/s2 c 5 m/s
rosijanka [135]

Answer:

a= 0.5m/s^2

Explanation:

Force applied on an object is known as

F=m.a  (Newton's second law states it)

a=F/m

a=5/10=0.5m/s^2

Some neodymium glass lasers can provide 100TW of power in 1.0 ns pulses at a wavelength of 0.26 micrometers. how much energy is
Aleksandr-060686 [28]

Answer:

 E = 10⁵ J

Explanation:

given,

Power, P = 100 TW

           = 100 x 10¹² W

time, t = 1 ns

           = 1 x 10⁻⁹ s

The energy of a single pulse is:-

Energy = Power x time

 E = P t

 E = 100 x 10¹² x 1 x 10⁻⁹

 E = 10⁵ J

The energy contained in a single pulse is equal to 10⁵ J
