How far will a rubber ball fall in 10 seconds?

Physics
1 answer:
Inessa [10]3 years ago
4 0

If it's not moving at all at the beginning of the 10 seconds, then it falls 490 meters straight down in 10 seconds.

(Note: This is true of all objects on Earth . . . rubber balls, feathers, grains of sand, school buses, battle ships . . . everything.  As long as air doesn't hold them back.  Anything falling from rest falls 490 meters in the first 10 seconds.)

Which set of atoms will form an ionic compound?
Oksanka [162]

Answer:

The answer is A)

Explanation:

An ionic compound is formed when one atom donates one or more electrons to one or more atoms of another element. Calcium has two valence electrons, which are donated to an atom of oxygen. So, an ionic compound is formed in the reaction involving one calcium atom with an oxygen atom.

A watermelon is thrown down from a skyscraper with a speed of 7.0\,\dfrac{\text m}{\text s}7.0 s m ​ 7, point, 0, space, start f
Degger [83]

Answer:

y = 17,89 m

Explanation:

Let us fixate the reference point in top of the building, from where the watermelon is thrown down. We will assume also that the positive axis of our system points up. We describe the watermelon’s motion with the equation:

 v_y^2 =v_0^2 + 2ay

Clearing the equation so we isolate y we have that:

 y = (v_y^2 - v_0^2 )/2a

Making a substitution with the values from the statement we have:

y = ((20 m/s)^2 - (7 m/s)^2)/(2*9,81 m/s^2) = 17,89 m]

So, this skyscraper is about 17,89 m tall; which is not very tall for a skyscraper but who am I to judge.  17,89 m is also the displacement of the watermelon from the point it was thrown down.

I hope everything was clear with my explanation. If I can help with anything else, just let me know. Have an awesome day :D

The speed of light in a vacuum is approximately 0.3 gm/s. What is the speed of light in meters per second?
klemol [59]

We have to convert Gm/s to m/s.

As  1 \ Gm/s = 10^9 \ m/s

Therefore the speed of light in vacuum,

c = 0.3 \ Gm/s = 0.3 \times 10^9 \ m/s \\\\ c= 3 \times 10^8 \ m/s

Thus, the speed of light in m/s is 3 \times 10^8 \ m/s
