Answer:

<h2>Group 1A</h2><h2>Ionic bond or electrostatic bond</h2>

Explanation:

Bond is a type of energy that is responsible to hold two or more same or different types of atoms.
On the basis of bond formation, the bond may be an ionic bond, covalent bond, coordinate bond and some other.
Group 7A elements like chlorine, bromine and some other has 7 electrons in its outermost shell so it receives 1 electron to complete its octet and thus the formation of chloride or other ions takes place having a negative charge.
So 1A group like sodium and some other has 1 electron in its outermost shell and thus loses 1 electron to obtain octane and thus form a positive ion.
Thus attraction takes place between positive ions like sodium ions and negative ions like chloride ions and a bond is formed that is known as an ionic bond or electrostatic bond.

- The school zone in front of your school has a posted speed limit of 25 mi/h, which is about 11 m/s. Let's

miv72 [106K]

Answer:

s = 38.7 m

Explanation:

First we calculate the distance covered during uniform motion of reaction time.

s₁ = vt

where,

s₁ = distance covered during uniform motion = ?

v = uniform speed = 11 m/s

t = time = 2.3 s

Therefore,

s₁ = (11 m/s)(2.3 s)

s₁ = 25.3 m

Now, we calculate the distance covered during decelerated motion:

2as₂ = Vf² - Vi²

where,

a = deceleration = -4.5 m/s²

s₂ = distance covered during decelerated motion = ?

Vf = Final Velocity = 0 m/s

Vi = Initial Velocity = 11 m/s

Therefore,

2(-4.5 m/s²)s₂ = (0 m/s)² - (11 m/s)²

s₂ = (-121 m²/s²)/(-9 m/s²)

s₂ = 13.4 m

the total distance will be:

s = s₁ + s₂

s = 25.3 m + 13.4 m

Two kilograms of air is contained in a rigid wellinsulated tank with a volume of 0.6 m3 . The tank is fitted with a paddle wheel

wolverine [178]

Answer:

$0.3\ \text{m}^3/\text{kg}$

$36\ \text{kJ}$

$18\ \text{kJ/kg}$

Explanation:

V = Volume of air = $0.6\ \text{m}^3$

P = Power = 10 W

t = Time = 1 hour

m = Mass of air = 2 kg

Specific volume is given by

$v=\dfrac{V}{m}\\\Rightarrow v=\dfrac{0.6}{2}\\\Rightarrow v=0.3\ \text{m}^3/\text{kg}$

The specific volume at the final state is $0.3\ \text{m}^3/\text{kg}$

Work done is given by

$W=Pt\\\Rightarrow W=10\times 60\times 60\\\Rightarrow W=36000\ \text{J}=36\ \text{kJ}$

The energy transfer by work, is $36\ \text{kJ}$

Change in specific internal energy is given by

$\Delta u=\dfrac{Q}{m}+\dfrac{W}{m}\\\Rightarrow \Delta u=0+\dfrac{36}{2}\\\Rightarrow \Delta u=18\ \text{kJ/kg}$

The change in specific internal energy of the air is $18\ \text{kJ/kg}$
