Answer: 11 electrons.
Explanation:
Atoms in their neural state, that is, uncharged or non ionized state, always have the same number of protons and electrons.
When they ionized, they will either gain or lose electron or electrons which will eventually make them either positively charged or negatively charged.
Given that an electrically neutral atom has 11 protons. It will definitely has 11 electrons orbiting around it’s nucleus
Answer:
Ff = 159 [N]
Explanation:
Since in the problem give us two values of friction coefficient one static and the other dynamic, it is important to keep in mind that in order to solve this problem we must know the conditions in which the sled is located. We can read that the sled is in motion, in this way we use the dynamic coefficient of friction.
The friction force is calculated as the product of normal force, by the appropriate coefficient of friction value.
Ff = N * μ
Ff = 636 * 0.25
Ff = 159 [N]
for example
1. drinking water at least after 1 hour beacuse if we immediately drink water just after meal it dilutes the HCL produced in our stomach which hinders the digestion process
2.picking up tomatoes for salads which contains oxalic acid
3.Cutting apples which contains malic acid with knife then after sometimes it will trun into brown due to oxidation of iron present in a apple.
Answer:
T/√8
Explanation:
From Kepler's law, T² ∝ R³ where T = period of planet and R = radius of planet.
For planet A, period = T and radius = 2R.
For planet B, period = T' and radius = R.
So, T²/R³ = k
So, T²/(2R)³ = T'²/R³
T'² = T²R³/(2R)³
T'² = T²/8
T' = T/√8
So, the number of hours it takes Planet B to complete one revolution around the star is T/√8
Answer:
Facilitated diffusion and active transport both utilize proteins to transport substances across membranes. Differences between active transport and facilitated diffusion 1. Active transport requires an input of energy, usually ATP, while facilitated transport does not.
