Explanation:
Friction literally helps us in ways we can't even think of. Without it I wouldn’t be able to hold my phone as easily as I am doing… Now coming to few other things that would have been impossible without friction are :
Sneezing and still staying in the same place.
Belt-pulley drive
Ease in normal walking
Holding a bottle for drinking water
A) 330 N
Explanation: Her weight must be evenly distributed between the chains (assuming they are at an even level), so you divide 660 by 2 and get 330
Cross eyed can result in double vision
Answer:
Continuous conduction occurs when each section of the axolemma has to be depolarized to threshold in sequence along the entire axolemma for a current to spread down the length of the axon.
Explanation:
Answer:
a)The approximate radius of the nucleus of this atom is 4.656 fermi.
b) The electrostatic force of repulsion between two protons on opposite sides of the diameter of the nucleus is 2.6527
Explanation:
= Constant for all nuclei
r = Radius of the nucleus
A = Number of nucleons
a) Given atomic number of an element = 25
Atomic mass or nucleon number = 52
The approximate radius of the nucleus of this atom is 4.656 fermi.
b)
k= = Coulombs constant
= charges kept at distance 'a' from each other
F = electrostatic force between charges
Force of repulsion between two protons on opposite sides of the diameter
The electrostatic force of repulsion between two protons on opposite sides of the diameter of the nucleus is 2.6527
