Answer:
8,000m
Explanation:
W=4,000kg
H=20m
PE= ?
---------------------
GPE=W x H
-----------------------
4,000kg x 20m = 8,000kg

Marine plants, such as algae, use CO2 to make energy. Ocean fertilization is the introduction into oceans of nutrients that encourage the growth of these plants. How can this technique affect the pH in oceans that already have higher than normal CO2 readings?
Answer:
the pH decreases and the ocean becomes more acidic.
Explanation:
A small change in the pH of seawater can have harmful effects on marine life, impacting chemical communication, reproduction, and growth.
Ocean fertilization can affect the pH in oceans that already have higher than normal carbon dioxide readings as it decreases the pH of the ocean water and it becomes more acidic.
What is Ocean fertilization?Ocean fertilization or the ocean nourishment is a type of technology which include carbon dioxide gas removal from the ocean water and it is based on the purposeful introduction of the plant nutrients to the upper ocean water to increase the marine food production and also for the removal of carbon dioxide gas from the atmosphere.
Ocean fertilization is a technique which affects the pH in the oceanic water and this already have higher than normal carbon dioxide readings. The pH of the oceanic water decreases and the ocean becomes more acidic in nature. A small change in the pH of ocean water can have harmful effects on the organism's life, impacting chemical communication, reproduction, and the growth.

What is different about water in different phases and containers?
Answer:Because the molecules can slip and slide around one another, water takes the shape of any container it is in. Despite the "hardness" of ice, the spacing of water molecules per unit volume is actually greater than it is for liquid water. Hence, ice is less dense than liquid water (which is why ice cubes float).
Explanation: Hope this helps.

Which is this the correct variable for the equation "____= displacement divided by time"?
velocity
speed
acceleration
The correct variable for the equation is velocity = displacement divided by time .
The distance traveled divided by the time passed is the definition of an object's average speed. Average velocity can be calculated as the displacement divided by the time. Velocity is a vector quantity.The vector quantity velocity (v), denoted by the equation v = s/t, quantifies displacement (or change in position, s), over change in time (t).What is the connection between time and velocity displacement?Time and distance are both factors in velocity. The pace at which an object changes its position is known as its velocity. Displacement / Time = VelocityThe change in velocity divided by the change in time is the definition of acceleration.

Force Fields test
Based On Newton’s Law of universal gravitation, Complete the following table
suppose that the acceleration of an object is zero. Does this mean that there is no force acting on it?
Answer:
not necessarily. It could mean that the forces acting on the object are balances and that the net force of the object is 0.
Explanation:
An example would be if you get a book on the table. It doesn't move; however, the force of gravity pulls downwards onto it while the normal force of the table will try to push up on it. These forces will be equal but opposite and are balanced.
What happens if an object has a negative acceleration?
the object is speeding up
the object is turning around
the object is slowing down
Answer:
An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. ... And if the acceleration points in the opposite direction of the velocity, the object will be slowing down. (I hope this helps)

A 3,000-N force gives an object an acceleration of 15 m/s^2. The mass of the object is
Hello,
QUESTION)According to the second Newton's Law,
✔ We have : F = m x a ⇔ m = F/a
m = 3000/15m = 200 kgThe mass of the object is therefore 200 kg.
