Explain why a Chef in a very busy restaurant would prefer a copper pot over an aluminum pot. A) The copper pot would heat faster

because it has a lower specific heat value. B) The copper pot would heat slower because it has a lower specific heat value. C) The copper pot would heat faster because it has a higher specific heat value. D) The copper pot would heat slower because it has a higher specific heat value.

<h2>Answer:</h2>

<u>The correct choice is  </u><u>(A) The copper pot would heat faster because it has a lower specific heat value.</u>

<h2>Explanation:</h2>

Specific heat is the amount of energy required to bring a change of one degree in any material when it is heated. Since specific heat capacity of copper is low so it means that it requires less amount of heat to make it hot that is why chef will prefer copper over aluminium

How does weight affect the time it takes an object to hit the ground?
ddd [48]

The heavier the object the faster it will fall. The lighter the object the slower to fall. You can test this for example with a rock and a piece of paper. The paper will take more time to for it to hit the ground rather than the rock which will be quicker.

A 0.58 kg mass is moving horizontally with a speed of 6.0 m/s when it strikes a vertical wall. The mass rebounds with a speed of
Sunny_sXe [5.5K]

Answer:

5.8\; {\rm kg\cdot m \cdot s^{-1}}.

Explanation:

If the mass of an object is m and the velocity of that object is v, the linear momentum of that object would be m\, v.

Assume that the initial velocity of the mass is positive (6.0\; {\rm m\cdot s^{-1}}.) However, the direction of the velocity is reversed after the impact. Thus, the sign of the new velocity of the object would be negative- the opposite of that of the initial velocity. The new velocity would be (-4.0\; {\rm m\cdot s^{-1}}).

Thus, the change in the velocity of the mass would be:

\begin{aligned}& (\text{Change in Velocity}) \\ =\; & (\text{Final Velocity}) - (\text{Initial Velocity}) \\ =\; & (-4.0\; {\rm m\cdot s^{-1}}) - (6.0\; {\rm m\cdot s^{-1}}) \\ =\; & (-10\; {\rm m\cdot s^{-1})\end{aligned}.

The change in the linear momentum of the mass would be:

\begin{aligned} & \text{change in momentum} \\ =\; & (\text{mass}) \times (\text{change in velocity}) \\ =\; & 0.58\; {\rm kg} \times (-10\; {\rm m\cdot s^{-1}}) \\  =\; & (-5.8\; {\rm kg \cdot m \cdot s^{-1}})\end{aligned}.

Thus, the magnitude of the change of the linear momentum would be 5.8\; {\rm kg \cdot m \cdot s^{-1}}.

How many swings would a 23 cm long pendulum make in 30 seconds?
iragen [17]

Is there any possible chance that at some point in your science
studies, sometime before you were given this question for your
homework, that maybe you might have encountered this formula
for the period of a simple pendulum ?

                   Period = (2 pi) √(length/gravity) .

If the length is 0.23 meter, and the
acceleration of gravity is 9.8 m/s²,
then the period is

                                 = (2 pi) √(0.23/9.8)

                                 =   0.963... second  (rounded)

That's how long it takes for a simple pendulum, 23cm long,
hanging on a massless string and not swinging too far to
the side, to complete one full swing left and right.

Now, if you can figure out how many periods of  0.963 second
there are in  30 seconds, you'll have your answer.  I'll leave
that part of it to you.
