Force = mass • acceleration
1) Find acceleration
-) 8kg ball
a= v/t
a= .2/ 10 = .02 m/s^2
Force = 8kg • .02 = .16N
-) 4kg ball
a= v/t
a= 1.0/ 10 = .1 m/s^2
Force = 4kg • .1 = .4N
Answer: The 8kg ball would need more force because it requires .16N, while the 4kg only need .4N .
The correct matches are as follows:
- malleability - the ability of metals to be shaped by hammering or pounding
- metallic bond - the bond formed when metal atoms share many mobile electrons
- alloy - a mixture of the atoms of a metal with another element
- ductility - the ability of metals to be formed into wires
- electron sea theory - metals bond to other metals by sharing many "floating electrons
<h3>What are metals?</h3>
Metals are elements which form positive ions by loss of electrons.
Metals are usually shiny, malleable and ductile.
Metal atoms combine are bonded to each other by metallic bonds.
Electron sea theory describe how mobile electrons surround positive atomic nucleus.
Alloys refer to a mixture of metals.
In conclusion, metal atoms form metallic bonds.

A, 40 degrees. Reflexion laws state that both incidence and reflection angles are the same.
Answer:
The evidence that the universe is expanding comes with something called the red-shift of light. Light travels to Earth from other galaxies. As the light from that galaxy gets closer to Earth, the distance between Earth and the galaxy increases, which causes the wavelength of that light to get longer. Distant galaxies are getting further away hinting at a point of origin. The composition of all observed matter in this universe points at a common origin point for all matter in the universe.

I was not able to write it here
so I did it somewhere else and attached the picture
i hope it helps
have a nice day
