Answer:

 equal to the weight of the fluid that the body displaces

Explanation:

Archimides' principle states the definition of buoyant force.

These are the imporant features of the buoyant force that you need to know:

Except for the very special vacuum condition, every body is immersed in a fluid.

The body is subject, at least, to two forces, its weight and the buoyant force.

The weight is the result of the gravitational attraction exerted by the planet, and is equal to the mass of the object by the gravitational acceleration (approximately 9.8 m/s² on Earth). It is directed vertically downward.

The buoyant force is the vertical upward force that the fluid exerts on the object and is equal to the weight of the volume of fluid displaced by the object.

The volume of fluid that the body displaces is equal to the immersed volume of the body.

An insulated Thermos contains 140 cm3 of hot coffee at 85.0°C. You put in a 15.0 g ice cube at its melting point to cool the cof

Pavel [41]

Answer:

$T = 69^o C$

Explanation:

Here at thermal equilibrium we can say that thermal energy given by Hot coffee is equal to the thermal energy absorbed by ice cubes

So here we have

$Q_{ice} = Q_{coffee}$

now since ice cubes are added into coffee when it is at melting temperature

So here we can say that final temperature of coffee is T degree C

Now we have

$m_1L + m_1c_1\Delta T_1 = m_2c_2\Delta T_2$

here we have

$m_1 = 15 gram$

L = 333 kJ/kg = 333 J/g[/tex]

$c_1 = c_2 = 4186 J/kg C = 4.186 J/g C$

$\Delta T_1 = T - 0$

$\Delta T_2 = 85 - T$

now we have

$15(333) + 15(4.186)(T - 0) = 140(4.186)(85 - T)$

$4995 + 62.79T = 49813.4 - 586.04T$

$648.83 T = 44818.4$

$T = 69^o C$

a student in your class says "electromagnetic waves can travel through outer space but mechanical waves can’t.” is it this stude

Kitty [74]

Answer:

Right

Explanation:

electromagnetic waves can travel through space (a vacuum) because it doesn't need a medium and its particles to propagate whereas a mechanical wave needs a medium to propagate. For example sound is a mechanical wave, sound vibrates off a mediums particles to propagate and for sound to be heard and travel
