Answer:

P waves move straight through all medium and S waves move only through solids in a curvy motion.

Explanation:

P waves are compression waves, this means that they can travel through all mediums, and all cores of earth, including the inner core, while S waves can only travel through solids, this makes them much more slower. P waves for example can be trackable on the other side of the earth from where the earthquake´s epicenter is, because they travel through the core of the earth, while S waves are only detectable near the epicenter of the earthquake.

An irregular lump of an unknown metal has a measured density of 5.50 g/mL. The metal is heated to a temperature of 153 °C and pl

Oliga [24]

Answer: $0.543J/g^0C$

Explanation:

Volume of metal = volume of water displaced = (30.0 - 25.0) ml = 5.0 ml

Density of metal = 5.50 g/ml

Mass of metal = $density\times volume =5.50\times 5.0=27.5g$

Volume of water = 25.0 ml

Density of metal = 1.0 g/ml

Mass of metal = $density\times volume =1.0\times 25.0=25.0g$

$heat_{absorbed}=heat_{released}$

As we know that,

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

$-[m_1\times c_1\times (T_{final}-T_1)]=[m_2\times c_2\times (T_{final}-T_2)]$ .................(1)

where,

q = heat absorbed or released

$m_1$ = mass of metal = 27.5 g

$m_2$ = mass of water = 25.0 g

$T_{final}$ = final temperature = ? $41.0^0C$

$T_1$ = temperature of metal = $153^oC$

$T_2$ = temperature of water = $25.0^oC$

$c_1$ = specific heat of lead = ?

$c_2$ = specific heat of water= $4.184J/g^0C$

Now put all the given values in equation (1), we get

$27.5g\times c_1\times (41.0-153)^0C=[25.0g\times 4.814J/g^0C\times (41.0-25.0)^0C]$

$c_1=0.543J/g^0C$

Thus the specific heat of the unknown metal sample is $0.543J/g^0C$

In which of the following are the symbols and names for the ions given correctly?

Ne4ueva [31]

Answer: Option (A) is the correct answer.

Explanation:

The name of $OH^{-}$ ion is hydroxide.

Name of $PO^{3-}_{3}$ ion is phosphite.

Name of $PO^{3-}_{4}$ ion is phosphate.

Name of $NH^{+}_{4}$ ion is ammonia.

Name of $C_{2}H_{3}O_{2}^{-}$ ion is acetate.

Name of $C_{2}O_{4}^{-}$ ion is oxalate.

Thus, we can conclude that the symbols and names for the ions given correctly is OH-:hydroxide
