What two things define an object's velocity? (Select two answers) this is 5th grade btw
1. acceleration
2. direction
3. weight
4. speed
Answer: speed and direction
Explanation: Velocity is a vector quantity, so it will have both speed and direction. So, the answer will be answers 2 and 4
You are riding in a car and speed up. What are the possibilities for the acceleration that your car undergoes? (Select all that apply.) Also i'm in 5th grade
-2.0 mph/s
-5.0 mph/s
2.0 mph/s
5.0 mph/s
Answer:
All of them
Explanation:
Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. In a car you could accelerate by hitting the gas or the brakes, either of which would cause a change in speed.

cornea
retina
iris
pupil
Answer:
Cornea
Explanation:
Internet
Answer:
Cornea
Explanation:
I need help please!!
Answer:
Explanation:
Solids, liquids and gases are three states of matter. In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. Particles in chemistry can be atoms, ions or molecules.
Which part of the eye shrinks and enlarges depending on the amount of light that is present?
visual cortex
retina
cornea
pupil
You measure the amount of chemical energy in some wood and it is 200J. Then you measure the amount of light and heat energy given off when you completely burn the wood. How much total energy (light and heat added together) would the wood give off when burned? How do you know?

Nancy observed that her plant reproduced when she cut off a leaf and planted it. Over time, the leaf grew into a full-grown plant. How is this offspring plant different from a plant that reproduces when one plant pollinates another? Explain your answer.
Answer:
The first plant grew from a seed as is, therefore, a "full plant" but the second one is not a "full plant" because it was a part of another so it will probably be weaker than the original.
Explanation:

GRAVITY IS THE INVICIBLE FORCE
Explanation:
Which of the following is described by the change in an object’s position? btw im in 5th grade
1. position
2. force
3. motion
Describe what would happen to a moving object if no unbalanced force acted upon it. btw im in 5th grade
Answer:
An object at rest will tend to stay at rest; an object in motion will tend to stay in motion with the same speed and direction, unless acted upon by an unbalanced force
Explanation:
Answer:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force. Objects resist changes in their velocity.
Explanation:
Once an object is in motion, what type of energy is being used? im in 5th grade btw
Answer:
Kinetic energy
Explanation:
Kinetic energy means you are in motion and creating friction and Potential energy is when you are staying in one place.

What happens to prey populations when predators eat some individuals
Answer: They grow more slowly, reproduce less, and populations decline. ... As predator populations increase, they put greater strain on the prey populations and act as a top-down control, pushing them toward a state of decline. Thus both availability of resources and predation pressure affect the size of prey populations.

"The silver trump of freedom had roused my soul to eternal wakefulness. Freedom had now appeared, to disappear no more forever. It was heard in every sound, and seen in every thing....I saw nothing without seeing it, I heard nothing without hearing it, and felt nothing without feeling it."
a. Frederick Douglass believed in freedom, and wanted all slaves to be free.
b. Frederick Douglass had a silver trumpet that inspired the other slaves to be free.
c. Frederick Douglass heard freedom in every word his masters spoke.
d. Frederick Douglass could think of nothing but freedom and how much he wanted it.
Answer:
The answer is B
Explanation:
In the text, Frederick makes it clear to us the silver trump not only inspired the slaves, but him also. He couldn't see the trump without looking at it. He couldn't hear the trump without listening to it, and he couldn't feel the trump without feeling it either. [ i hope this helped :) ]

Scientists often rely on _____ as evidence when looking at an animal’s reproductive success.
A. data
B. inferences
C. conclusions
D. reasoning
Scientists often rely on data as evidence when looking at an animal’s reproductive success. Thus, option A is correct.
What is reproduction?Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Reproduction is the supreme quality of living things. Reproduction has been defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them.

Nancy observed that her plant reproduced when she cut off a leaf and planted it. Over time, the leaf grew into…
The offspring plant from the leaf cutting is genetically identical to the parent plant, while a plant that reproduces through pollination will result in genetically diverse offspring due to the combination of genetic material from two parent plants.
The offspring plant that grows from a leaf cutting is a result of a type of asexual reproduction called vegetative propagation. In this process, a portion of the parent plant (such as a leaf, stem, or root) is detached and planted, giving rise to a new plant that is genetically identical to the parent. This means that the offspring plant has the same genetic makeup as the parent plant, making it a clone. The genetic information of the offspring plant is an exact copy of that in the parent plant.
On the other hand, when a plant reproduces through pollination, it involves the transfer of pollen from the male reproductive organ (stamen) of one plant to the female reproductive organ (pistil) of another plant of the same species. This sexual reproduction results in offspring that are genetically diverse. During pollination, the male gametes (sperm) combine with the female gametes (eggs) to form a zygote, which develops into a new plant with a unique combination of genetic traits from both parent plants.
In summary, the key difference between the two types of reproduction lies in the genetic makeup of the offspring. Asexual reproduction, as observed with the leaf cutting, produces genetically identical offspring (clones), while sexual reproduction through pollination generates genetically diverse offspring with unique combinations of genetic traits from both parent plants.
