<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

Answer:

The maximum mass that can fall on the mattress without exceeding the maximum compression distance is 16.6 kg

Explanation:

Hi there!

Due to conservation of energy, the potential energy (PE) of the mass at a height of 3.32 m will be transformed into elastic potential energy (EPE) when it falls on the mattress:

PE = EPE

m · g · h = 1/2 k · x²

Where:

m = mass.

g = acceleration due to gravity.

h = height.

k = spring constant.

x = compression distance

The maximum compression distance is 0.1289 m, then, the maximum elastic potential energy will be the following:

EPE =1/2 k · x²

EPE = 1/2 · 65144 N/m · (0.1289 m)² = 541.2 J

Then, using the equation of gravitational potential energy:

PE = m · g · h = 541.2 J

m = 541.2 J/ g · h

m = 541.2 kg · m²/s² / (9.8 m/s² · 3.32 m)

m = 16.6 kg

The maximum mass that can fall on the mattress without exceeding the maximum compression distance is 16.6 kg.

The four tires of an automobile are inflated to a gauge pressure of 2.2 105 Pa. Each tire has an area of 0.023 m2 in contact wit

Stels [109]

Answer:

Force, F = 20240 N

Explanation:

It is given that,

Pressure exerted by the four tires of an automobile, $P=2.2\times 10^5\ Pa$

Area of each tire, $A=0.023\ m^2$

Area of 4 tires, $A=0.092\ m^2$

We know that the pressure exerted by an object is equal to the force per unit area. Its formula is given by :

$P=\dfrac{F}{A}$

$F=P\times A$

$F=2.2\times 10^5\times 0.092$

F = 20240 N

So, the weight of the automobile is 20240 N. Hence, this is the required solution.

You have a string with a mass of 0.0127 kg. You stretch the string with a force of 9.33 N, giving it a length of 1.93 m. Then, y

melomori [17]

Answer:

wavelength = 0.968 m

frequency = 39.02 Hz

Explanation:

given data

mass = 0.0127 kg

force = 9.33 N

length = 1.93 m

to find out

wavelength and Frequency

solution

we know here linear density that is

linear density = $\frac{mass}{length}$ .........1

linear density = $\frac{0.0127}{1.93}$

linear density = 6.5803 × $10^{-3}$ kg/m

wavelength will be here

wavelength = $\frac{2L}{n}$ ..............2

here n = 4 for forth harmonic

wavelength = $\frac{2*1.93}{4}$

wavelength = 0.968 m

and

frequency will be for 4th normal mode of vibration is

frequency = $\frac{4}{2L} \sqrt{\frac{tension}{linear\ density} }$ ..........3

frequency = $\frac{4}{2*1.93} \sqrt{\frac{9.33}{6.5803*10^{-3}} }$

frequency = 1.036269 × 37.654594

frequency = 39.02 Hz
