Answer:
The essential characteristics of an object in equilibrium is acceleration of the object must be zero.
Explanation:
Equilibrium: An object acted upon by several forces is said to be in equilibrium if it does no it moves or rotate. Equilibrium can be defined as the state of stability of an object.
Condition for equilibrium
(i) The resultant force acting on the object must me equal to zero.
(ii) The sum of moment acting on the object must be equal to zero.
But.
F = ma..................... Equation 1
Where F = net force , m = mass, a = acceleration.
from the equation above,
For F = 0 N, a must be equal to zero.
<em>From the above, the essential characteristics of an object in equilibrium is acceleration must be zero</em>
Answer:
Use the form of equation:
Q=mL
You have the specific latent heat of vaporization L = 2.260*10^{6}
And Q, the heat energy supplied, which equals 1695 KJ = 1695*10^{3} J
So you can get the mass by substitution in the formula below.
T² caries directly as R³ .
This is Kepler's 3rd law of planetary motion .
A single replacement reaction occurs when two different cations switch places to combine with the same anion. One element forms a compound while another element is released from the compound. In a single replacement reaction, or single displacement reaction, a single<span> uncombined element replaces another in a compound.
So you're answer is probably c.

Answer:
10.29 cm/s
Explanation:
Discharge in to the bowl = 17.0 cm³/s
Diameter of the bowl, d₁ = 1.45 cm
Now,
Rate at which water level rise at its diameter = 
also,
Area of cross-section = 
or
Area of cross-section = 1.651 cm²
Therefore,
Rate at which water level rise at its diameter = 
or
Rate at which water level rise at its diameter = 10.29 cm/s
