Answer:
1.51783893986
Explanation:
One kilogram is equal to 9.81 Newtons
You have 14.89N, divide this by 9.81 and u get the mass in KG
so u do 14.89/9.81 = 1.51783893986 or 1.52kg (2dp)
Answer:
5p
Explanation:
We are given that a tin has 50 electrons.
We have to find in which subshell electrons experience the lowest effective nuclear charge.
We know that the electron in outermost shell experience the lowest effective nuclear charge.
Electronic configuration is given by
Outer most sub-shell is 5p. Therefore, 5p subshell experience the lowest effective nuclear charge because the distance of 5p sub-shell is large from nucleus.
Answer: 5p
Bcoz when you place a magnet close enough the magnet attracts or repals without any other fore we dont touch the magnet so it is non contact
Advantages
-renewable
-emissionless
-reduces distance required for electricity to travel
- can be produced effectively on small scale
Disadvantage
-No continual supply-doesnt function on cloudy days or at nightime
-expensive
-inefficient, best solar panels today are only 40% efficient, most are worse
Answer:
It is always the same as it was before the collision.
