Answer:

It takes 3 minutes.

Explanation:

The distance between the two subways is 3 miles.

The train travels at an average speed of 60mph (miles per hour).

\frac{60miles}{1 hour} * \frac{1hour}{60minutes} = \frac{1mile}{1minute}

We have to convert hours to minutes and we do that by cancelling out the hours and replacing it with minutes.

There are 60 minutes in an hour so we use that, 1 hour/60 minutes and multiply it to the existing speed we have.

The result is 1 mile per minute.

We then multiply the miles by 3 since that is how much we want and we get 3 minutes.

You skip north for 12 minutes to your best friend's house that is 1.5 kilometers away. What is your average velocity?
bagirrra123 [75]

Answer:

The average velocity is 7.5 km/h

Explanation:

Let's convert minutes to hours so our answer can be given in a common units of km/hour:

12 minutes = 12/60  hours = 0.2 hours

Now we estimate the average velocity calculating the distance travelled over the time it took:

1.5 / 0.2 km/h = 7.5 km/h

Brass requires more energy than silver

Aluminum requires more energy than copper

Aluminum requires more energy than brass

Explanation:

The specific heat capacity of a substance indicates the amount of heat energy required to raise 1 kg of that substance by 1 degree in temperature.

Mathematically:

C=\frac{Q}{m\Delta T}

where

Q is the heat supplied to the substance

m is the mass of the substance

\Delta T is the change in temperature

Therefore, the higher the specific heat capacity of a substance, the more energy is needed to increase its temperature.

Here we can compare the specific heat capacity of the materials mentioned:

Silver: C=0.233 J/gK

Brass: C=0.380 J/gK

Platinum: C=0.130 J/gK

Aluminium: C=0.910 J/gK

Copper: C=0.390 J/gK

Therefore, the correct statements are:

Brass requires more energy than silver

Aluminum requires more energy than copper

Aluminum requires more energy than brass
