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)

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.

Describe the two characteristics of the general surface wind circulation pattern associated with this low-pressure system
Which location on the map, W, X, Y, or Z, most likely has the greatest wind speed? Describe one piece of evidence on the map indicating that this location has the greatest wind speed.
Answer: I would Say X.
Explanation: I say this because the numbers are higher near X. I'm not sure because the map does not say much. Hope this helped. Have A Good Day!!!
The wind speed is highest at point X, due to high pressure area and counterclockwise flow.
The given problem is based on the wind circulation system. In climatology, the wind circulation system is referred to as the movement of air relative to the surface of Earth. The characteristics of the general wind circulation pattern associated with low-pressure system is as follows:
The Wind flow will be towards the low pressure region, and the air rises in the atmosphere.As air rises, the moisture gets into condensation and clouds are formed along with the precipitation.The evidence for determining the greatest wind speed is that, "Wind moves counterclockwise around low-pressure area and clockwise around the high-pressure area". Now, the pressure and speed for the wind is,
[tex]P=\dfrac{1}{2} \rho v^{2}[/tex]
here, P is the pressure and v is the speed of wind. So, higher the pressure, higher will be speed.
As per the given map, point X represents the area of counterclockwise movement of wind, so probably it should have high pressure, hence speed is higher at point X.
Thus, we can conclude that the wind speed is highest at point X, due to high pressure area and counterclockwise flow.

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).

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.

Answer:velociy :)
Explanation:
Due to the connection between electric and magnetic phenomena, the magnetic field generated by an MRI machine can be used to excite the positive charges in hydrogen atoms. These hydrogen atoms emit radio waves that can be used to form an image of their locations. The main source of hydrogen atoms in the human body is water. Which of the following are limitations this method might place on the images that can be generated?
Select all that apply.
A
Detecting hydrogen atoms allows for certain parts of the body to be imaged better than others.
B
Areas without large amounts of water are harder to map.
C
Hydrogen is not present in the human body.

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.
