What happens if an object has a negative acceleration?
the object is speeding up
the object is turning around
the object is slowing down

Answers

Answer 1

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?

Answers

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.

There could be a force on all sides pushing at the same speed to make it not move hypothetically, but in generic terms in most circumstances yes

Please tell me if if these statements are true or false

1. Light cause the same change to all materials.
2. All light is the same, whether it comes from the sun, a light bulb, or anywhere else.
3.All light can be seen.
4.Light can travel through materials that you cannot see through, like wood or aluminum foil.

Please explain why. (if its too much to explain don't worry about it, i'll try to do it myself)

1. False- light usually doesn’t cause changes to certain materials.

2. True (I think) I don’t really know how to explain this one

3. False- Not all light can be seen especially when light can travel

4. False- Certain hard materials light won’t be able to go through because of its density.

Sorry about the 2nd one and I’m not 100% on this but hope this helps.

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?

Answers

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.
