A snail can move approximately 0.30 meters per minute then it would cover 4.5 meters in 15 minutes.
The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is a meter/second. The generally considered unit for speed is a meter per second.
As given in the problem a snail can move approximately 0.30 meters per minute and we have to calculate the distance covered in 15 minutes.
speed of the snail = 0.30 meters per minute
time = 15 minutes
distance covered by the snail = speed ×time
distance covered by the snail = 0.30 ×15
distance covered by the snail = 4.5 meters
Thus, the distance covered by the snail in the 15 minutes would be 4.5 meters.

B. before = 7, after = 4
C. before = 4, after = 7
D. before = 9, after = 7
Answer:
A before = 7, after = 9
Explanation:
Answer:
The change in the density of the air inside the syringe is due to the change in temperature. When the air inside the syringe is cooled, it contracts, causing the density to increase.
The principle that explains this phenomenon is known as Charles's Law, which states that the volume of a gas is directly proportional to its temperature, provided the pressure and the amount of gas remain constant.
In this case, the density of the air doubles when the syringe is cooled, implying that the volume of the air inside the syringe is halved. Therefore, if the density of the air when cooled is 2.4 kg/m³, the density of the air at room temperature (when the volume is twice as much) would have been half of this value, or 1.2 kg/m³.
So, the density of the air at room temperature was 1.2 kg/m³.
Answer: Cats and Dogs
Explanation:
That’s actually the silly term. The real answer depends how harsh it’s raining. Mostly it’s just bugs but sometimes a bird might lose control but it is very rare.
B. the number of protons and neutrons
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.
