The lemon trees will always be the same so they are the constants. The independent variable is the water amount because it is changing. The dependent variable is the amount of lemons because it is the variable being tested. (If we change the amount of water how many lemons will be produced?)
Answer:
The time taken by the ship to cover the distance, t = (x/25) s
Explanation:
Given data,
The initial velocity of the ship, u = 20 m/s
The final velocity of the ship, v = 30 m/s
The average velocity of the ship, V = (20 + 30)/ 2
= 25 m/s
The distance covered by the ship, d = x m
Then the time taken by the ship to cover the displacement is,
d = V x t
∴ t = d / V
Substituting the values,
t = x / 25
t = (x/25) s
Hence, the time taken by the ship to cover the distance, t = (x/25) s

because "This means that when you rubbed the plastic comb along your hair, your hair resisted the movement of the comb and slowed it down. The friction between two surfaces can cause electrons to be transferred from one surface to the other."
Answer:
a) 
b) 
c) 
Explanation:
Given:
- diameter of hole in the tank,
- position of the hole form the tank bottom,
- initial level of turpentine in the tank before the leakage,
- level of turpentine in the tank after the repair of leakage,
- diameter of the tank,
- density of turpentine oil,
a)
Now, volume of turpentine spilled:
where:
area of the cross section of the tank's volume
b)
When the tank was full the liquid level was highest:
so velocity form the height of the hole will be given as:
<u>Now we have the flow rate of the spillage given by:</u>
c)
Total time the leak was active can be calculated as:
