Answer:

D) The spring has potential energy and the hands have kinetic energy.

Explanation:

Since the hands are in motion and the spring is wound, the spring has potential energy and the hands have kinetic energy.

A train is traveling north. it goes 200 km /hr for 2.5 hours how far did the train go.
DerKrebs [107]

Answer:

500Km

Explanation:

This question is an example of speed, distance, time.

The formula for working out the distance is: Speed*Time

To work this out you would need to multiply the speed of 200Km/h by the time of 2.5 hours, this gives you 500 Km. This is because the formula to work out the distance is speed * time.

In adittion, if the train is traveling at 200km per hour then that means that over the course of an hour the distance travelled would be 200Km. So, by multiplying the speed by the time you are working out how far it travelled in that given time.

1) Multiply 200 by 2.5.

200*2.5=500Km

A traveling electromagnetic wave in a vacuum has an electric field amplitude of 98.9 V/m . Calculate the intensity ???? of this
Pani-rosa [81]

Answer:

intensity = 12.98 W/m^2

Energy = 3.93 J

Explanation:

As we know that the magnitude of electric field intensity is given as

E = 98.9 V/m

now we know that intensity of the wave is given as the product of energy density and speed of the wave

intensity = \frac{1}{2}\epsilon_0 E^2 c

intensity = \frac{1}{2}(8.85 \times 10^{-12})(98.9)^2(3\times 10^8)

intensity = 12.98 W/m^2

so intensity is the energy flow per unit area per unit of time

so the energy that flows through the area of 0.0259 m^2 in 11.7 s is given as

Energy = Area \times time \times intensity

Energy = 0.0259(11.7)(12.98)

Energy = 3.93 J
