Explanation:

A) 1 kg = 1000g

2500kg = 2500000g

B 1 hour = 3600 sec

335 hour = 1206000sec

C 1day = 24 hours

1 hour = 3600 sec

24 hours = 86400sec

A milk truck carries milk with density 64.6 lb/ft3 in a horizontal cylindrical tank with diameter 12 ft. (a) Find the force exer
7nadin3 [17]

Answer:

F = 351×10³lb

Explanation:

Given the density

ρg = 64.6lb/ft³

Diameter d = 12ft

The tank is horizontally cylindrical. The vertical distance from the top to the bottom of the tank is h = 12ft

The pressure in the tank is

P = ρgh = 64.6 × 12 = 775.2lb/ft²

The force exerted on one end of the tank is therefore F = PA = 775.2 × πd² = 775.2π×12²

F = 351×10³lb.

explain why for thousands of years people believed that stars moved across Earth's sky. Explain why we now have a different expl
Anarel [89]

Answer:

Ptolemy proposed a model, he reference system is centered on the Earth

Copernicus, proposed a deferent system,  this system is centered on the Sun, where it is at the origin of the system

Explanation:

Thousands of years ago, Ptolemy proposed a model to explain the movement of the planets and stars in the sky, in this model the reference system is centered on the Earth, so each body is orbiting in different spheres around the Earth as its center, this system had very complicated calculations and curves to be able to explain the orbits of the planets.

More recently Copernicus, proposed a deferent system, this system is centered on the Sun, where it is at the origin of the system, in this system the movement of the planets are ellipses, which is a much simpler explanation and has been widely accepted, in current systems the reference system is fixed in the bodies more massive, since this simplifies the explanation of the movements.

Light shines through atomic Hydrogen gas. It is seen that the gas absorbs light readily at a wavelength of 91.65 nm. What is the
hoa [83]

Answer:

n = 19

Explanation:

\lambda = Wavelength of the light absorbed = 91.65 nm = 91.65 x 10⁻⁹ m

n_{2} = nth level = n

n_{1} = 1

Using conservation of energy

\frac{hc}{\lambda} = (13.6\times1.6\times10^{-19}) (\frac{1}{n_{1}^2} - \frac{1}{n_{2}^2} )\\\frac{(6.63\times10^{-34})(3\times10^{8})}{(91.65\times10^{-9})} = (13.6\times1.6\times10^{-19}) (\frac{1}{1^2} - \frac{1}{n^2} )\\2.17\times10^{-18} = (21.76\times10^{-19}) (\frac{1}{1^2} - \frac{1}{n^2} )\\n = 19
