<u>Answer:</u>

Metals possess low ionisation energy hence it loses electrons easily. The nucleus and the inner shell electrons is called the kernel.

The electron which gets lost leaves the influence of one kernel and moves towards the other.

Thus the electrons will be in constant movement and gets delocalized.

The electrostatic forces between the positive kernel and the sea of mobile electrons is called as metallic bond.

Metal atoms possess this type of attractive forces in between them.

For example the metal atoms of a sheet of copper possess this type of chemical bond between the atoms.

Thus, Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions

In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions

John rides his bike with a constant speed of 12 miles per hour. How far can he travel in 2 hours?
Gwar [14]

Answer:

24 miles

Explanation:

Make a proportion

He is traveling at a constant rate of 12 miles/hour, so

he can go 12 miles in 1 hour, and x miles in 2 hours

12/1=x/2

Multiply both sides by 2

2*12/1=x/2 *2

24=x

So, in 2 hours he can travel 24 miles

A piece of string 2 meters and has a mass of 5g. On one end of the string hangs a 200 g mass. Find the tension of the string and
viktelen [127]

Explanation:

It is given that,

Length of the string, l = 2 m

Mass of the string, m=5\ g=5\times 10^{-3}\ kg

Hanged mass in the string, m'=200\ g=0.2\ kg

1. The tension in the string is given by :

T=m'g

T=0.2\times 9.8

T = 1.96 N

2. Velocity of the transverse wave in the string is given by :

v=\sqrt{\dfrac{T}{M}}

m = M/l

v=\sqrt{\dfrac{Tl}{m}}

v=\sqrt{\dfrac{1.96\times 2}{5\times 10^{-3}}}

v = 28 m/s

Hence, this is the required solution.

A wave has a speed of 50 m/sec. If its frequency is 100 Hz,
Gre4nikov [31]
Wave speed= Frequency x Wavelength


-> Wavelength= Wave speed divide Frequency


-> 50m/s divide 100Hz= 0.5m

Our textbook describes a common model for friction (both static and kinetic) in which the area of contact between interacting su
Mkey [24]

Contact area is not a factor of the amount of friction force acting between two bodies in contact, preventing rolling or sliding

Reasons:

  • Friction force is the product of the normal reaction and the coefficient of friction.
  • The coefficient of friction is higher in softer tires than hard tires which are required to be wider to reduce the pressure that can cause deformation withstood by hard tires.
  • The wide tires in drag racing cars can be thought of being made from the soft compound tire material having a higher coefficient of friction that increases the friction force.

Other advantages of wide tires are;

  • Increased traction
  • Shorter stopping distance
