Yo sup??
we can solve this problem by applying Newton's 2nd law
F*t=Δp
p=momentum
pi=mu=1500*30
pf=mv=m*0=0
Therefore
F*3=1500*30
F=15000 N
Hope this helps.
Answer
321.8 g CaF2
321.5 g Al2(CO3)3
Answer:
d) osmotic pressure equal to that of blood
Explanation:
Answer is not a) because pH is concentration of positive hydrogen in solution but it not note all solutes. Answer is not b) because like answer a), it not note solutes without charge and, additionally it not note the pressure equilibrium when solvent flows through a membrane . Answer is not c) because it can be more or less water (solvent).
<span>systems are involved in this process, How are they involved?
The way that you touching </span><span> a hot pan and yanking your hand away is your body saying that "Aye, This isn't right" and our nerves go to the source where you had touched the hot pan... sending the signals to your brain, Your hand might have a small blister..the reason why that is, because its your bidy naturally healing its self with an internal wound</span>
Answer:

<em><u>Step by step explanation</u></em><em><u>:</u></em>
<em>Given:</em>
Mass of given sample (m) = 2.50 g
Initial temperature (T1) = 25°C
Final temperature (T2) = 20°C
Heat Energy Q = 12 cal
<em>T</em><em>o </em><em>find:</em>
<em>
</em>
<em>Solution</em><em>:</em>
We know that,
<em>Specific</em><em> </em><em>heat</em> <em>of </em><em>any </em><em>substance </em><em>is </em><em>directly</em><em> </em><em>proportional</em><em> </em><em>to </em><em>the </em><em>mass </em><em>and </em><em>change </em><em>in </em><em>temperature.</em>
Represented by equation,

Where,
<em>Q = Heat Energy</em>
<em>m = mass of given sampl</em><em>e</em>
<em>c = specific heat</em>
<em>∆T = change in </em><em>temperature</em>
Substituting corresponding values,
<em>
</em>
We also know that,

multiplying above answer by 4.184,
