D 15000 J

Answers

Although this question doesn't ask a question, I'm guessing that the
question is probably "How much work is done in moving the object ?"

If my hunch is correct, then the answer is not listed among the choices.

Work = (force) x (distance)

         = (100 N) x  (5 m)  =  500 joules.

Well whaddaya know!  Maybe that wasn't the question.

When a soccer ball is headed from one player #1 to player #2 across the soccer field, what is the projectile

Answers

Explanation :

Any object that is thrown in space that moves under the action of gravity is known as a projectile. Every object in the universe comes down due to gravitational force.

When a soccer ball is headed from the player 1 to player 2 across the soccer field, the soccer ball will act like a projectile.

In projectile motion, we can calculate certain parameters like

  • Time of flight
  • Range of projectile
  • Maximum height

In apex the answer is "soccer ball"

Use the term cell differentiation in a sentence

Answers

Stem cells begin to transfer into different types of cells in the human body in a process known as cell differentiation.

Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types. 

Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.

If the answer is for Ed genuity :

Fill in the blank below with the word that best completes the sentence.
