For the same generic reason that table salt doesn't taste or behave
like the corrosive sodium or the poisonous chlorine that it's made of.

The physical and chemical properties of compounds in general are
very different from the characteristics of any of their constituent
elements in the pure elemental state.

-- Water doesn't act anything like Hydrogen or Oxygen.

-- A candle doesn't act anything like Carbon or Hydrogen.

-- Dry ice doesn't act anything like Carbon or Oxygen.

-- DNA doesn't act anything like Hydrogen, Oxygen, Nitrogen,
Carbon or Phosphorus. (We are lucky.)

Assume that a clay model of a lion has a mass of 0.225 kg and travels on the ice at a speed of 0.85 m/s. It hits another clay mo

Charra [1.4K]

Answer:

Final velocity will be equal to 0.321 m/sec

Explanation:

We have given mass of clay model of lion $m_1=0.225kg$

Its speed is 0.85 m/sec, so $v_1=0.85m/sec$

Mass of another clay model $m_2=0.37kg$

It is given that second clay is motionless

So its velocity $v_2=0m/sec$

Now according to conservation of momentum

Momentum before collision will be equal to momentum after collision

So $m_1v_!+m_2v_2=(m_1+m_2)v$ , here v is velocity after collision

So $0.225\times 0.85+0.37\times 0+(0.225+0.37)v$

$0.595v=0.191$

v = 0.321 m/sec

So final velocity will be equal to 0.321 m/sec

An object moves from point A to B to C to D and finally to A

Nataly [62]

here's the solution,

The radius of the circle = 3 km

distance covered = circumference of the circle,

So, Circumference :

=》

$2\pi r$

=》

$2 \times 3.14 \times 3$

=》

$18.84$

(a). Distance covered by moving object is 18.84 km

(b). 0 km

now, Displacement of the object is 0 km, because displacement is the shortest distance from stating point to the destination, but the object returns back to the starting point, hence magnitude of displacement is 0.
