What is the acceleration of a 100-kg mass that has a force of 50 n acting on it?

In an evaporation of water experiment, the initial mass of water in a beaker was 10.5775 +/- 0.0002 g. After some time, the mass

muminat

Answer:

Explanation:

The theory of propagation of error in case of addition and subtraction states that maximum errors are added in absolute terms in both the operation of addition and subtraction . So in this case the subtracted value will be

10.5775 - 10.3005

= .2770 g

errors will be added ie in subtracted value we can find error to the tune of

.0002 + .0002 = .0004 g

So the subtracted value will be written as

.2770 ± .0004

Sirius and its companion orbit around a common center of mass with a period of 50 years. The mass of Sirius is 2.35 times the ma

s2008m [1.1K]

Answer:

1 solar masses

Explanation:

-Sirius has to maintain equilibrium with it's companion.

-Let x be the mass of Sirius and y be the mass of it's companion.

-From the question, we know that Sirius is 2.35 times heavier than it's companion:

$\frac{x}{y}=2.35\\\\\frac{x}{y}=\frac{2.35}{1}$

Hence, the mass of it's companion is 1 solar masses

A cardinal (Richmondena cardinalis) of mass 4.00×10−2 kg and a baseball of mass 0.146 kg have the same kinetic energy. What is t

sp2606 [1]

Answer:

0.5232

Explanation:

the cardinal and the baseball has the same kinetic energy

$\frac{1}{2} m_{c} v_{c} ^{2} = \frac{1}{2} m_{b} v_{b} ^{2}$

$m_{c}v_{c}^{2} = m_{b}v_{b}^{2}$

$[4.0X 10^{-2} ]v_{c} ^{2} = [0.146]v_{b} ^{2}$

$\frac{v_{c} }{v_{b} } = \sqrt{\frac{0.146}{4.0 X 10^{-2} } }$

$\frac{v_{c} }{v_{b} } = 1.910$

Ratio of momentum

$\frac{p_{c}}{p_{b}} = \frac{m_{c}v_{c}}{m_{b}v_{b}} = \frac{ (4.0 X 10^{-2} )(1.910v_{b} )}{0.146v_{b} }$

$\frac{p_{c}}{p_{b}} = \frac{4.0 X 10 ^{-2} X 1.910 }{0.146} = 0.5232$

Explain the runaway refrigerator effect and the role it may have played in the evolution of Mars.

Fiesta28 [93]

Answer:

Explained

Explanation:

The runway refrigerator effect and the role it would have played in the evolution of Mars can be summarized as follows

The weak gravity of Mars does not allow it have a gaseous atmosphere over it. The thin atmosphere would have lead to lower temperature on mars.In in turn would have lead to freezing of gases thus lowering the temperature further. The thinner atmosphere and colder temperature would lead to loss of most water in the planet.
