Which statement best describes how the temperature of the oceans surface water varies

1 answer:

8 0

<span>heat capacity→ water has a high heat capacity, and salt water has an even higher one, so the temperatures of the oceans remain within a small range because As the heat rises you get more evaporation which actually cools the ocean down (Specific Heat of Water; Heat needed to break down hydrogen bonds)</span>

At which position is the roller coaster car's amount of potential energy about equal to the amount of kinetic energy?

meriva

It will be potential because the roller coaster is going down so it’s not giving off energy to the roller coaster.

A 3.50-meter length of wire with a cross-sectional area of 3.14 × 10-6 meter2 is at 20° Celsius. If the wire has a resistance of

maks197457 [2]

Answer:

$5.6\times 10^{-8}\ Ohm.m$

Explanation:

Resistivity is given by $\rho=\frac {AR}{L}$ where A is cross-sectional area, R is resistance, L is the length and $\rho$ is the reistivity. Substituting 0.0625 for R, 3.14 × 10-6 for A and 3.5 m for L then the resistivity is equivalent to

$\rho=\frac {3.14\times 10^{-6}\times 0.0625}{3.5}=5.60714285714285714285714285714285714285\times 10^{-8}\approx 5.6\times 10^{-8}\ Ohm.m$

A steam engine absorbs 1.98 × 105 j and expels 1.49 × 105 j in each cycle. assume that all of the remaining energy is used to do

VikaD [51]

B) The heat absorbed by the engine is $Q_{in} = 1.98 \cdot 10^5 J$ while the heat expelled is $Q_{out} = 1.49 \cdot 10^5 J$ , therefore the work done by the engine is the difference between the heat absorbed and the heat expelled:
$W=Q_{in} - Q_{out} = 1.98 \cdot 10^5 J - 1.49 \cdot 10^5 J = 0.49 \cdot 10^5 J$

a) The efficiency of the engine is the ratio between the work done by the engine and the heat absorbed, therefore:
$\eta= \frac{W}{Q_{in}} = \frac{0.49 \cdot 10^5 J}{1.98 \cdot 10^5 J}=0.247 = 24.7\%$
