Answer:

Explanation:
Given that
Height = h
Radius = R
From energy conservation

At point B
The minimum speed to complete the the circle

So the kinetic energy at point B




Without falling off at the top (point B)




It will sink because it is heavier. The density of water 1.00 g/ml
Answer:
Explanation:
1. when both sides of the reactants and the products are equal
like h+oh ⇒ h20
hydrogen has 2 atoms on both sides and oxygen has one on both sides
2. no they are put to balance the equation
3. nope they are treated equally as all the other states
4. no if u are talking about a formula unit like NaCl for example it is aqueous not each element taken on its own if u are talking about just elements then i said before all states are treated equally
5. yup
