4 0

Answer:

Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure. In fact, if they are going to form ions, Group 14 elements form positive ions. Carbon and silicon form covalent bonds. Carbon's millions of organic compounds are all based on shared electrons in covalent bonds.

abruzzese [7]

Answer:

K. E = (mv^2)/2

Explanation:

  1. 25000= (1800× v^2)/2
  2. 25000×2= (1800× v^2)
  3. 50000=1800×v^2
  4. 50000/1800= v^2
  5. 27.77777777= V^2
  6. 5.27038=V

Velocity (V) = 5.270 m/sec

Please mark branliest if you are satisfied with the answer. Thanking you in anticipation.

A snowmobile has a mass of 540 kg. A constant force acts on it for 41 seconds. The snowmobile’s initial velocity is 9 m/s and fi
LekaFEV [45]

Answer:

F = 329.27 N

Explanation:

given,

mass of snowmobile = 540 Kg

time = 41 s

intial velocity = 9 m/s

final velocity = 34 m/s

Force = ?

Force is equal to change in momentum per unit time

F = \dfrac{dp}{dt}

F = \dfrac{m(v_f-v_i)}{t}

F = \dfrac{540(34-9)}{41}

F = \dfrac{540\times 25}{41}

    F = 329.27 N

Force applied to the snowmobile is equal to F = 329.27 N
