Answer:

Explanation:

According to Newton's third law, every action has an equal and opposite reaction

so it tells us that the force exerted by the earth on the spacecraft is equal to the force exerted by the spacecraft on the earth. But we do not see the earth moving towards the spacecraft because the inertia of the spacecraft is very less than the inertia of the earth.

How much heat is absorbed from a 56.00 g sample of Mercury when its tempreature change is 289K?

AveGali [126]

Heat required to raise the temperature of mercury is given as

$Q = ms\Delta T$

here given that

m = 56 g

s = specific heat capacity of mercury = 0.140 J/g C

$\Deta T = 289 k$

now here we have

$Q = 56 * 0.140 * 289$

$Q = 2265.76 J$

so it required 2265.76 J of heat

0.500 kg of ethyl alcohol at 33.0°C

Bingel [31]

Answer:

26.06

Explanation:

One thing to note first is that, after the ethyl alcohol and water is mixed, the heat energy (Q) is equal for both of them. So:

<h3>m c ΔT (water) = m c ΔT (ethyl) </h3>

Second thing to note is that ΔT is just the absolute value of the final temperature of the solution minus the initial temperature of the ethyl, or water. So the previous equation becomes:

<h3>m c (Tfin - Tinit) (water) = m c (Tfin - Tinit) (ethyl) </h3>

And since we know the mass and specific heat of the water and ethyl alcohol, we can substitute those in:

(I wrote 33 - Tfin for ethyl because ΔT should be a positive number in this case)

Now finally we can expand out the parenthesis and use a little algebra to solve:

Now use algebra to separate the Tfin coefficients onto one side and everything else on the other, and we get:

And when you divide both sides be 3318, you get your answer of:

<h3>Tfin = 26.06118 or 26.1 for significant figures</h3>

Hope that helps!
