If it is in its ground state, it will be in the level 1s
Answer:
Since the density of salt water is higher than that of fresh water.
Explanation:
Less salt water will be displaces and the ship will float higher.
Answer:
Description 1 matches C.
Description 2 matches A.
Description 3 matches D.
Description 4 matches B.
Explanation:
Description 1 matches C. From graph C, we can see that the <em>distance remains constant at a particular value</em>. Hence, the car is <em>not traveling</em> and hence it is <em>stopped.</em>
Description 2 matches A. <em>Speed is determined by the gradient of a distance-time graph</em>. A depicts a <em>linear graph</em> which tells us that the <em>gradient is constant </em>and hence the car is at <em>constant speed</em>. The fact that the<em> distance is increasing</em> shows that the<em> car is moving forward</em>.
Description 3 matches D. Graph of D becomes <em>less steeper as time progresses</em>. This tells us that the <em>gradient of the graph is decreasing </em>and hence the <em>speed of the car is decreasing.</em>
<em />
Description 4 matches B. Graph B shows <em>distance being decreased.</em> This tells us that the <em>car is coming back</em>.
Explanation:
The acceleration of an object is equal to the rate of change of velocity. Its mathematical form is given by :
Where
v is final velocity, u is initial velocity and t is time taken
The SI unit of velocity is m/s and that of time is s. The SI unit of acceleration is 
If final velocity is more than the initial velocity, acceleration is positive.
If the final velocity is less than the initial velocity, the acceleration is negative. It is also known as deceleration.
Hence, all the statement is true.

the mass and characteristics of that substance.
