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
Answer:
Period for 1 revolution is 1.75 seconds
Explanation:
given data
revolutions R = 8
time t = 14 seconds
to find out
What is the period
solution
we know that Period is the time per revolution
so here period formula that is express as
period = 
= 
= 0.57 revolution in one second
so in 1 revolution = 
seconds
so in 1 revolution = 1.75 seconds
so period for 1 revolution is 1.75 seconds
Based on the relative velocity of the man with respect to the boat and the dock:
- Distance covered in 4.0 seconds relative to the boat = 8 m
- Distance covered in 4.0 seconds relative to the dock = 56 m
<h3>What is relative velocity?</h3>
Relative velocity is the velocity of a body relative to another body which serves as a reference point.
Relative velocity is a vector.
Considering the velocity of the man and the boat:
The relative velocity of the man with respect to the boat = 2.0 m/s
Distance covered in 4.0 seconds relative to the boat = 2.0 m/s * 4.0 s
Distance moved = 8 m
Relative velocity of the man with respect to the dock = 12 + 2 = 14 m/s
Distance covered in 4.0 seconds relative to the dock = 14.0 m/s * 4.0 s
Distance moved = 56 m
In conclusion, the relative velocity is velocity with respect to a reference point.

these include the troposphere (0 to 16 km), stratosphere (16 to 50 km), mesosphere (50 to 80km) and thermosphere (80 to 640km). The boundaries between these four layers are defined by abrupt changes in temperature, and include respectively the tropopause, stratopause and mesopause.
<h3>What is Free-fall acceleration?</h3>
The acceleration is constant and equal to the gravitational acceleration g which is 9.8 m/s at sea level on the Earth.
As we know that charge and its sign that remains in equilibrium is under gravity must be such that it will balance the gravitational force by electric force,
mg =qE
and its sign must be negative so that it will have upward electric force
so it is
The charge of a particle of mass is
