Answer:
The property to form polar covalent bond and hydrogen bonds
Explanation:
Liquid water exhibits the property of surface tension, functions as solvent for ionic and polar covalent bonded molecules and have high specific heat.
All these properties can be credited to the property of water to form hydrogen bonds with liquid water molecules where the hydrogen bonding results when hydrogen atom of a water molecule is attracted to a more electro negative oxygen atom of other water molecule in the neighborhood while polar covalent bond formation results in the the water molecule as it is a polar covalent molecule as it contains hydrogen atom and an electronegative oxygen atom which results in the charge distribution in the molecule.
Answer:
Self-motivation is the surest way to stay focused. Nearly all the most significant tasks in life are tests for our motivation. Facing challenges and achieving success requires focus; this means we need to be responsible for our motivation. People who are motivated towards achieving their goals are focused on success. The following ideas will help you stay focused and motivated in your work and studies.
Explanation:
Answer:
2.06 m/s
Explanation:
From the law of conservation of linear momentum, the sum of momentum before and after collision are equal. Considering this case where we have frictionless surface, no momentum is lost in the process.
Momentum before collision
Momentum is given by p=mv where m and v represent mass. The initial sum of momentum will be 9v+(27*0.5)=9v+13.5
Momentum after collision
The momentum after collision will be given by (9+27)*0.9=32.4
Relating the two then 9v+13.5=32.4
9v=18.5
V=2.055555555555555555555555555555555555555 m/s
Rounded off, v is approximately 2.06 m/s
