Estimate the mass of water that must evaporate from the skin to cool the body by 0.45 ∘C. Assume a body mass of 95 kg and assume
hram777 [196]

Answer:

0.0757 kg

Explanation:

m = mass of the body = 95 kg = 95000 g

ΔT = change in the temperature of the body = 0.45 °C

c = specific heat capacity of the body = 4.0 J/(g °C)

M = mass of water evaporated

L = latent heat of vaporization of water = 2260 J/g

Using conservation of heat

Heat gained by water = heat lost by body

ML = m c ΔT

M (2260) = (95000) (4.0) (0.45)

M = 75.7 g

M = 0.0757 kg

If the Hubble Space Telescope is 598 m above the surface of the Earth and is traveling at 7.56 x 103 m/s, how long does it take
viva [34]

Answer:

5069.04 seconds

Explanation:

The parameter we are looking for is called the Orbital period of the Hubble Space Telescope.

It is given as:

T = \sqrt{\frac{4\pi^2r^3 }{GM} }

where r = radius of orbit of Hubble Space Telescope

G = gravitational constant = 6.67408 * 10^{-11} m^3 kg^{-1} s^{-2}

M = Mass of earth

We are given that:

r = radius of the earth + distance of HST from earth

r = 6.38 * 10^6 + 598 = 6380598 m

M = 5.98 * 10^{24} kg

Therefore, T will be:

T = \sqrt{\frac{4*\pi^2 * 6380598^3 }{6.67408 * 10^{-11} * 5.98 * 10^{24}}}

T = 5069.04 secs

The orbital period of the Hubble Space Telescope is 5069.04 seconds.
