A plane is flying horizontally with speed 292 m/s at a height 3880 m above the ground, when a package is dropped from the plane.

the acceleration of gravity is 9.8 m/s 2 . neglecting air resistance, when the package hits the ground, the plane will be 1. ahead of the package. 2. directly above the package. 3. behind the package. 008 (part 2 of 4) 10.0 points what is the horizontal distance from the release point to the impact point?

The plane is straight above the package when it hits the ground. 
Find in what way long a free fall from a height of 4240 m takes: s = 1/2 gt^2 
t^2 = 2s/g 
t^2 = 2* 3880/9.8 = 791.8367
t = √791.8367
t = 28.1396 seconds 
Now find the horizontal displacement with v = 292 m/s in 28.1396 s: 
s = v*t 
s = 292 * 28.1396 = 8216.76 m

serious [3.7K]

Answer: The chemical formula for the compound of these two elements is PbS_2

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here metal lead is having an oxidation state of +4 called as Pb^{4+} cation and sulphur non metal has oxidation state of -2 called as S^{2-}. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral PbS_2

The chemical formula for the compound of these two elements is PbS_2

The power lines are at a high potential relative to the ground, so there is an electric field between the power lines and the gr
Makovka662 [10]

Answer:

The tube should be held vertically, perpendicular to the ground.

Explanation:

As the power lines  of ground are equal, so its electrical field is perpendicular to the ground and the equipotential surface is cylindrical. Therefore, if we put the position fluorescent tube parallel to the ground so the both ends of the tube lie on the same equipotential surface and the difference is zero when its  potential.

And the ends of the tube must be on separate equipotential surfaces to optimize potential. The surface near the power line has a greater potential value and the surface farther from the line has a lower potential value, so the tube must be placed perpendicular to the floor to maximize the potential difference.

jeka94

Answer:

c. Sound travels slower than light.

Explanation:

We see any thing because of the light emitted or reflected by it. Whereas the sound is carried by the sound waves. The speed of light is more than the speed of sound. This is the reason the family saw the fireworks first and then heard the sound.

The same can be experienced during the sighting of a Jet plane or a rocket where, we see them way before we can hear the roaring sound of its engines.
