Answer:
It stays the same.
Explanation:
Entropy of a system either increases or remains constant in any process, it never decreases.
Answer:
a = 156.14 m/s^2
Explanation:
Using the laws of newton:
∑F = ma
where ∑F is the sumatory of forces, m the mass and a the aceleration.
so:
F -
= ma
where F is the force from the hockey stick and
is the force of friction.
Replacing values, we get:
(30.2N) - (3.5N)= (0.171kg)a
Finally, solving for a:
a = 156.14 m/s^2
Answer:
Polar covalent bond
Explanation:
When two atoms of unequal electro- negativity comes together to form bonds , there is unequal sharing of electrons between them , one of them acquaring partial positive and partial negative charge . Then they make bond due to mutual attraction.
Bond formation in HCl in gaseous state is an example .
