One atom of silicon can properly be combined in a compound withtwo atoms of oxygen to produce silicon dioxide because silicon is very similar to carbon, as it is in the same group as carbon is in, therefore, it is able to make four bonds.
Moreover, Silicon has 4 valence electrons. In order to form an ionic bond, silicon<span> would have to gain or lose 4 electrons.</span>
Answer:
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
Explanation:
We have equation of motion
S = ut + 0.5at²
Here u = 0, a = g and t = 9.3 s
We have equation of motion v = u +at
Substituting
v = u +at
v = 0 + 9.8 x 9.3 = 91.14 m/s
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
A quadratic equation is a parabola and a linear equation is a straight line.
- Quadratic Equation is an equation in which the power of variable mostly x is two.
- Standard quadratic equation is
- Any linear equation have form like
- The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum.
- Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to risk of stumbling or falling.
- Astronauts on the moon were protected from the extreme temperatures by their spacesuits. The suits had several layers of insulating material covered by a highly reflective outer layer.
