A physicist is investigating a beam of laser light of wavelength 550 nm. The light strikes a target that is 189 meters away from

the source of the light. What is the travel time of the light from the source to the target? Let the speed of light c = 3.00 × 10^8 m/s.

When the switched on, what type of energy is moving through the circuit?
BabaBlast [244]

Answer:

Heat energy

Explanation:

Electrons are flowing through the circuit, they pass through a resistor, in this case a light bulb. The energy is then transformed into light and heat energy.

Is the temperature and density of Earth's crust high or low? Why?
Setler [38]

Answer:

The crust is the first layer of the earth. It is split up into two parts the continental crust, and the oceanic crust. The oceanic crust takes up 71% of the earths crust, and the other 29% of the crust is continental. The continental is made up of igneous rocks, and the oceanic crust is made up of sedimentary and basalt rocks. The continental crust is older than the oceanic crust, some of the rocks are 3.9 billion years old. The density average of the oceanic crust is 3g/cm. The average density of the continental earth is 2.7g/cm. The temperature of the crust is around 200-400 degrees Celsius. The crust is about 60 km thick under a continent and 5 km thick under the ocean. The crust is constantly moving.  The crust doesn't even make up 1% of the earth!  The crust is the layer were tectonic plates can be found.

The minimum breaking distance d in feet for a typical vehicle can be modeled with the equation d(v) = 0.045v2, where v is the ve
xxTIMURxx [149]
<span>To find the kind of transformation that describes this change from d(v) = 0.045v2 to d(v) = 0.039v2, find the relation between the two functions:

0.045/.039 = 45/39 = 15/13

The you have to multiply the first function times 13/15 to transform it to the second function.

When you multiply by a factor less than one you are compressiong the function vertically (if you multiply by a factor greater than 1 you are stretching vertically).

On the other hand, that the distance to stop the minimum braking distance will be smaller with the second function.

Then, the answer is that the transformation is a vertical compression by a factor of 13/15 and the braking distance will be less with optimum new tires than with tires having more wear.
