An Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds. What is the average acceleration of the sprinter? A.
0.9 m/s

B.
110 m/s

C.
110 m/s²

D.
1.1 m/s²

Answers

Answer 1
Answer:

Answer

Average accleration is 1.1 m/s² .

Option (D) is correct .

Explanation:

Formula

Average\ accleration = (v_(final)-v_(initial))/(t_(final)-t_(initial))

As given

An Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds.

v_(initial) = 0\ meter\ per\ second

v_(final) = 11\ meter\ per\ second

t_(initial) = 0\ second

t_(final) = 10\ second

Putting all the values in the formula

Average\ accleration = (11-0)/(10-0)

Average\ accleration = (11)/(10)

Average accleration = 1.1 meter per second²

Therefore Average accleration is 1.1 m/s² .

Option (D) is correct .


Answer 2
Answer: an Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds. 1.1 m/s² is the average acceleration of the sprinter

Explanation:

Water is made of two hydrogen atoms and one oxygen atom bonded together. Julia is describing how water undergoes a physical change when it boils. She says that the particles shift to be farther apart and that the oxygen and hydrogen separate. She also says that the total mass of the steam is the same as the initial water, and that heat energy was required to cause the change. She finishes her description by saying that the steam can be turned back into water if it is cooled.what was her mistake?

Describe how do ions form?

Answers

Answer:

Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by a combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms.

Explanation:

Answer:

Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.
