Answer:

1.35 m

Explanation:

First, find the time it takes to land.  Given in the x direction:

Δx = 21 m

v₀ = 40 m/s

a = 0 m/s²

Find: t

Δx = v₀ t + ½ at²

(21 m) = (40 m/s) t + ½ (0 m/s²) t²

t = 0.525 s

Next, find the height.  Given in the y direction:

v₀ = 0 m/s

a = 9.8 m/s²

t = 0.525 s

Find: Δy

Δy = v₀ t + ½ at²

Δy = (0 m/s) (0.525 s) + ½ (9.8 m/s²) (0.525 s)²

Δy = 1.35 m

Round as needed.

If the angle of incidence of a light source to a shiny surface is 30 degrees, what will the angle
Virty [35]
<h3>Answer: D) 30</h3>

Angle of incidence always equals angle of reflection. Think of a tennis ball being hit into a wall. The ball will bounce off at the same angle that it approached with. The angles mentioned are formed through the line called the "normal", which is the line perpendicular to the surface.

Electronegativity is<br>____ at the top of the periodic table.​
DanielleElmas [232]

Answer:

Electronegativity is a chemical property at the top of the periodic table

Explanation:

electronegativity is a chemical property that measures the ability of an atom to attract a bonding pair of electrons when it is part of a compound

it's a property of atom that increases as you go to the right and up.

One example is the Pauling scale. it is a numerical scale of electronegativities. It was first developed by Linus Pauling.

it is commonly used to calculate the ability of electronegativity to attract electrons to itself.

The most common electronegative element is Flourine, having an assigned value of 4.0, ranging down to caesium and francium, having the least electronegative at 0.7
