Answer:

I think Jamal should put the purple car so where point A(s) faces in N and then B faces the back. Or, he can move the green car to where it should be part D(n) faces S and part C faces the back. I think this because if you keep the purple car with N + N facing each other, it won't move the car at all and it would force each other apart. Also, the same thing for the green car, if you keep the green car with S + S facing each other, it won't move the car at all and it would force each other apart.

Hope this helps and brainliest plz?

Answer: 557nm

Explanation:

Visible light has been known to have its wavelengths in the range between 400 to 700 nanometres (nm), or 4*10^-7 to 7*10^-7 m. This wavelength is between infrared and ultraviolet. Infrared has longer wavelengths and while on the other hand ultraviolet has shorter wavelengths. The wavelength of visible light has a frequency of approximately 430 to 750 terahertz (THz).

tanΦ= 0.0039/4 = 9.75*10^-4

Φ= tan^-1 (9.75*10^-4)

Φ= 0.056

λ= (5.7*10^-4) * sin 0.056

λ= 5.57*10^-7m

λ= 557nm

HELP PLEASE!!
sweet-ann [11.9K]

Answer:

C. More of the heat is transferred to the kinetic energy of the copper atoms than to the kinetic energy of the water molecules.

Explanation:

Both equal masses of water and copper were heated at the same temperature. Since copper is a good conductor of heat compared to water, its  absorbs more heat. Which in-turn increases the rate of vibrations of the atoms in the copper mass, thus increasing their kinetic energy.

In the case of water, its molecules displaces one another after being heated to a higher temperature compared to neighboring molecules. So that the heated molecule becomes less dense and floats to the surface of water.

This property of copper makes it to be heated to a higher final temperature than the water.

If a jet is travelling horizontally at 100m/s at a height of 500m above the ground and a jet drops a bomb to the ground. Where d
Westkost [7]

The bomb strike the ground relative to the point at 1km . B

<h3>How to determine the distance</h3>

Using the equation

h = 1/2 gt^2

500 = 1/2 * 10* t^2

500 = 5t^2

t = √500/5

t = √100

t = 10seconds

To find the distance,

Distance = velocity * time

Distance = 100 ÷ 10

Distance = 1000m = 1km

Therefore, the bomb strike the ground relative to the point at 1km . B
