A. a cubic meter of lead
B. a cubic meter of feathers
C. none of the above
D. a cubic meter of snow
E. a cubic meter of air
F. a cubic meter of astronomy books
A physical object which would experience the greatest gravitational acceleration is: A. a cubic meter of lead.
What is a gravitational force?A gravitational force is also referred to as gravity and it can be defined as a universal force of attraction which acts between two (2) physical objects, especially by pulling them together.
What is a gravitational acceleration?A gravitational acceleration can be defined as the rate of change of the velocity of an object in free fall with respect to time, especially due to effect of a gravitational force. Also, gravitational acceleration is usually measured in meter per seconds square (m/s²).
Generally speaking, gravitational acceleration is highly dependent on the weight of a physical object. This ultimately implies that, the greater the weight of a physical object, the higher would be the gravitational acceleration it experiences.
In this context, we can reasonably infer and logically deduce that a physical object which would experience the greatest gravitational acceleration is a cubic meter of lead because it has the least weight in comparison to the other objects.

In a class of 6, there are 2 students who forgot their lunch.
If the teacher chooses 2 students, what is the probability that both of them forgot their lunch?
Answer: 1/15
Explanation:
Since it's a class of 6, and there are 2 students who forgot their lunch. The probability of firs choosing a student who forget their lunch will be 2 out of 6 which is 2/6.
When the next student who forget their lunch is picked there'll be 5 students left which means the probability then will be 1 out of 5 which is 1/5.
Therefore, the if the teacher chooses 2 students, the probability that both of them forgot their lunch will be 1/3 multiplied by 1/5 which will be:
= 1/3 × 1/5
= 1/15

O competition
O international trade
Answer:D
Explanation:
The process that helps countries import things they cannot make while allowing them to specialize in exports is known as international trade. Therefore, option D is correct.

B. They have gap junctions that allow molecules to pass through the cell wall without having to cross the cell membrane.
C. They produce hormones, which travel to neighboring cells and carry out local regulation processes.
D. They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Answer:
D. They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell communication can be defined as the process which typically involves living cells detecting and responding to signals such as hormones in their surrounding or environment.
Basically, the main purpose of cell communication is to enable living cells interact and work together so as to perform their respective functions and important processes that are necessary for survival.
Hence, the statement which best describes cell communication processes that are present in bacteria, yeast, and multicellular organisms is that, they release chemical messengers to communicate with cells they may or may not be in direct contact with.

If an object accelerates at 4 meters per second
per second, downriver, in a river flowing at 3
meters per second, how fast is it going at 10
seconds
Based on the calculations, the final velocity of this object is equal to 43 meters per second.
Given the following data:
Acceleration = 4 meters per second per second.
Initial velocity = 3 meters per second.
Time = 10 seconds.
What is an acceleration?An acceleration can be defined as the rate of change of the velocity of an object with respect to time. Also, acceleration is usually measured in meter per seconds square.
How to calculate the acceleration of an object?Mathematically, the acceleration of this object can be calculated by using this formula:
a = (V - U)/t
Where:
V represents the final velocity.U represents the initial velocity.t represents the time measured in seconds.a represents the acceleration.Making V the subject of formula, we have:
V = U + at
Substituting the given parameters into the formula, we have;
V = 3 + 4(10)
V = 3 + 40
Final velocity, V = 43 meters per second.
