In each of the given pairs, choose which element will have the bigger atom. Give reasons for your choice. (a) Mg (atomic number
Dafna1 [17]

Answer:

Mg (atomic number 12)

K (atomic number 19)

Explanation:

The size of an atom is estimated in terms of its atomic radius.

The atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance (d) between two nuclei in the solid - state of metals.

  • Across a period, atomic radii decrease progressively from left to right.
  • This is due to the progressive increase in the nuclear charge without increase in the number of electronic shells.
  • Down a group, atomic radii increase progressively due to the successive shells of electrons being added which have been compensated for by the increase in nuclear charge.

Cl is further right of Mg in the third period

K is below Na in the first group

A student is investigating gravity and falling objects. She drops three balls and times how long it takes each ball to hit the g
nignag [31]

Answer:C

Explanation: This is because the time for the 26 gram ball was around 6 seconds longer which if they were dropped at the same height then the ball with more mass would fall faster because of its gravitational pull.

Calculate the linear momentum for each of the following cases. (a) A proton with mass 1.67 ✕ 10-27 kg moving with a velocity of
Oliga [24]

Answer:

8.4168\times 10^{-21}\ kgm/s upward

4.725 kgm/s to the right

468.6 kgm/s southwest

1.782\times 10^{49}\ kgm/s forward

Explanation:

When the mass of an object is multiplied by its velocity we get momentum

m = Mass

v = Velocity

Proton

p=mv\\\Rightarrow p=1.67\times 10^{-27}\times 5.04\times 10^6\\\Rightarrow p=8.4168\times 10^{-21}\ kgm/s

The momentum of the proton is 8.4168\times 10^{-21}\ kgm/s upward

Bullet

p=mv\\\Rightarrow p=0.015\times 315\\\Rightarrow p=4.725\ kgm/s

The momentum of the bullet is 4.725 kgm/s to the right

Sprinter

p=mv\\\Rightarrow p=71\times 6.6\\\Rightarrow p=468.6\ kgm/s

The momentum of the sprinter is 468.6 kgm/s southwest

Earth

p=mv\\\Rightarrow p=5.98\times 10^{24}\times 2.98\times 10^4\\\Rightarrow p=1.782\times 10^{29}\ kgm/s

The momentum of the sprinter is 1.782\times 10^{29}\ kgm/s forward
