Answer: the water level would rise since the pebble displaces minimal water compared to the boat.
Explanation:..........
Answer:
move upward with increasing speed
I draw fbd diagram , see in figure
when lift going upward -
F - mg = ma
f = m( a + g)
scale so highest reading
The total charge on the helix is
- Q =

Height of one turn = 
Horizontal distance in one turn = 
<h3>
length of spring in one turn is</h3>

So, the total length of spring

Therefore, charge on spring

Answer:
For the first situation, we first need to find the mass of the second train car.
In order to do that, we apply the conservation of the amount of movement:

and we have as a result:
m2 = 289.6875
For the second situation, also we will apply the conservation of the amount of movement:

and we have as a result:
V = 2.64 (it is moving to the right)

➷ The dependent variable is the variable that is being measured.
In this case, the dependent variable is the amount of force required to stretch the spring.
