Answer: Two glass marbles bounce off each other.
Explanation:Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. If total kinetic energy is not conserved, then the collision is referred to as an inelastic collision.
An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example. In an elastic collision, both momentum and kinetic energy are conserved. Almost no energy is lost to sound, heat, or deformation.
Operators can avoid damaging SAV's by only operating at high tides, and watch where they are going, because past scientific studies have shown that propellers from machines are known to damage existing SAV's<span />
a) 1.57 m/s
The sock spins once every 2.0 seconds, so its period is
T = 2.0 s
Therefore, the angular velocity of the sock is
The linear speed of the sock is given by
where
is the angular velocity
r = 0.50 m is the radius of the circular path of the sock
Substituting, we find:
B) Faster
In this case, the drum is twice as wide, so the new radius of the circular path of the sock is twice the previous one:
At the same time, the drum spins at the same frequency as before, therefore the angular frequency as not changed:
Therefore, the new linear speed would be:
And substituting,
So, we see that the linear speed has doubled.
When writing an electron configuration in orbital form, you put the last noble gas configuration in front, for vanadium it's (Ar). The s-block is filled with its capacity of 2 electrons since vanadium is a regular transition metal. The first d subshell, 4d, puts electrons into the 3rd shell not the outer shell. So it has 2 valence electrons. The exceptions to this rule are chromium, molybdenum, copper, silver and gold, which put one of the s electrons into the d shell.
