nikitadnepr [17]
I assume the element has 5 valence electrons (not neutrons).  The similar properties are shared between y and z  since they have the same number of valence electrons.  This is what is primarily responsible for chemical behavior.

A 2 kg ball of clay moving at 35 m/s strikes a 10 kg box initially at rest. What is the velocity of the box after the collision?
Ainat [17]

Answer:

V = 5.83 m/s

Explanation:

Given that,

Mass of a ball of a clay, m = 2 kg

Initial speed of the clay, u = 35 m/s

Mass of a box, m' = 10 kg

Initially, the box was at rest, u' = 0

We need to find the velocity of the box after the collision. Let V be the common speed. Using the conservation of momentum to find it.

mu+m'u'=(m+m')V\\\\V=\dfrac{mu+m'u'}{(m+m')}\\\\V=\dfrac{2\times 35+10\times 0}{2+10}\\\\V=5.83\ m/s

So, the velocity of the box after the collision is equal to 5.83 m/s.

how much work is done in holding a 15N sack of potatos while waiting in line at the grocery store for 3 minutes
SpyIntel [72]
The strict scientific definition of work is

                   Work = (force) x (distance) .

If you exert a force but not through any distance, then technically,
no work has been done.  You may break out in sweat, and your arm
may start to tremble and ache.  But according to Physics, no work
has been done until you lift that bale a little higher.
