The correct answer is
<span>C) Amount of heat absorbed or released is doubled if quantity is doubled. If a different substance with half the specific heat capacity is used, the amount of heat absorbed or released is cut in half.
In fact, the amount of heat released or absorbed is given by:
</span>

<span>where
m is the mass of the substance
Cs is the specific heat capacity of the material
</span>

is the change in temperature
<span>
We can see that Q is directly proportional to both m (mass, or quantity of the substance) and Cs (specific heat capacity). So if the quantity (m) is doubled, the amount of heat (Q) is doubled as well. Similarly, if the specific heat capacity (Cs) is cut in half, the amount of heat (Q) is cut in half as well.</span>
You can see the periodic motion as the projection over the diameter of a point moving with a circular motion.
The Amplitude will be the radius of the circumference and ω is the angular frequency (or speed) for both motions.
In the periodic motion, you will have maximum velocity at the center and it will be zero at the extremities, where the projection changes direction, while the acceleration will be maximum at the extremities and zero at the center.
The displacement will then be:
x(t) = A · cos(ωt)
And from this (using a little bit of calculus):
v(t) = A · ω · sin<span>(ωt)
a(t) = </span><span>A · <span>ω</span>² · cos(ωt)</span>
Answer:
1320 kg I think
Explanation:
Here you can just substitute into the equation. ∆v means change in speed
this gives you (1100x24)/20
Answer:
Neptune
Explanation:
"Answer: Pluto is usually farthest from the Sun. However, its orbit "crosses" inside of Neptune's orbit for 20 years out of every 248 years. Pluto last crossed inside Neptune's orbit on February 7, 1979, and temporarily became the 8th planet from the Sun.

Answer:
past temperature, composition of gases in the atmosphere
Explanation:
Cylindrical cones can be drilled out from the core of glaciers to calculate past temperatures. The air bubbles in the cones can also be used to determine the composition of air in the past yars. This information provides us a means to analyze the trend of global warming and change in concentratinos of green house gases over the years.
