How proton ,neutron and electrons are alike

Physics
1 answer:
insens350 [35]2 years ago
8 0
Protons and neutrons are both inside the nuclei of the atom while the electrons are spinning around. they also make up the mass of the atom. 
protons are positively charged while neutrons are neutral. 
Protons and electrons are alike in the number while they are opposites in the charge because protons are positive while electrons are negative. Their quantity makes up the atomic number for an element.

Which of the following is true about Viscosity of liquids:
White raven [17]
Viscosity of liquids is essentially the 'thickness' of the liquid. For instance, honey and water have different viscosities. Honey has a higher one and therefore, liquids with high viscosity do not flow as well as liquids with low viscosity (water).

A hockey puck is sliding across a frozen pond with an initial speed of 9.3 m/s. It comes to rest after sliding a distance of 42.
kondaur [170]

Answer:

The coefficient of kinetic friction between the puck and the ice is 0.11

Explanation:

Given;

initial speed, u = 9.3 m/s

sliding distance, S = 42 m

From equation of motion we determine the acceleration;

v² = u² + 2as

0 = (9.3)² + (2x42)a

- 84a = 86.49

a = -86.49/84

|a| = 1.0296

F_k = \mu_k N = ma

where;

Fk is the frictional force

μk is the coefficient of kinetic friction

N is the normal reaction = mg

μkmg = ma

μkg = a

μk = a/g

where;

g is the gravitational constant = 9.8 m/s²

μk = a/g

μk = 1.0296/9.8

μk = 0.11

Therefore, the coefficient of kinetic friction between the puck and the ice is 0.11
