Lack of basic services in community
There are many consequences that result from the lack of basic services in a community but i shall focus on these three as they are very major impacts
-Educational Impact
Basic service like Water,Electricity ,Mobility and close Proximity to market place has a major impact on the ability of a person pursue educational attainments.we live in a modern world and without power(as) electricity we can not do much of studying in this times
-Insecurity
The Human mind is built with a default setting of Survival.Without the basic services provide persons of low moral will tend to go into illegal acts to survive as the basic needs are necessary for survival
-Poverty
For a community to grow it is necessary that the right environment is made available for growth and if these requirements are not meet in form of basic services in community the community falls under the threat of falling into poverty
In conclusion
The Three consequences of lack of basic services in community are
-Educational Impact

How many electrons can carbon accept from other atoms while bonding? (1 point)
two
six
eight
four
Answer: Four electrons
Explanation:
The number of electrons that can be accepted by carbon from other atoms while bonding is four. The correct option is D.
What is chemical bonds?A chemical bond is what holds atoms in molecules together. Electrostatic forces between positively charged atomic nuclei and negatively charged electrons, the positions of which in space are determined by quantum mechanics, generate bonds.
Atoms form chemical bonds to strengthen their outer electron shells. The chemical bonding type maximizes the stability of the atoms that form it.
Carbon forms covalent bonds with other elements or carbon atoms. Carbon compounds are extremely diverse, with sizes ranging from one to thousands of atoms.
Because carbon has four valence electrons, it can form four covalent bonds to achieve a full outer energy level.
Thus, the correct option is D.

While on a scavenger hunt, a student walks 500 m north, 200 m east, 300 south and finally 400 m west What is the net displacement and direction of the student?
Answer:
282.84 m toward Northwest
Explanation:
d = √(500-300)² + (400-200)²
=√(200²+200²)
= √(40000+40000)
= √ 80000
= 282.84 m
direction => Northwest
-
[tex]d = \sqrt{(500 - 300)^2 + (400 - 200)^2 } [/tex]
[tex]d = \sqrt{200^{2} + 200 ^{2} } [/tex]
[tex]d = \sqrt{40.000 \times 2} [/tex]

You have 50L of water, it froze. So find its new volume. Density of water is 1000kg/m^3 or 1kg/L, density of ice is 920kg/m^3 or 0.92kg/L.
Answer:
D (density) = Mass / Volume
V (ice) = Mass / Density = 50000 g / .92 kg / L
V = 50 kg / .92 kg / L
1 Liter of water weighs 1 kilogram = 50 L weighs 50000 g
V = 54.3 L the mass does not change upon the change of phase (freezing)
the right-hand tube of the manometer is open to the atmosphere. The pump has been operated so that the mercury levels differ, as shown, by 250 mm. The density of mercury is 13 600 kg / m3. i) Calculate the pressure, in Pa, due to the 250 mm column of mercury.
Answer:
P(ressure) = d g h = density * gravity * height
P = 13600 * 9.8 * .25 = 33,300 Pa
Check: 1 atm = 76 cm = 760 mm height = 1.01 * 10E5 Pa
h = 1.01 * 10E5 / 9.8 * 13600 .758 m = 758 mm for 1 atm
250 / 758 = 1/3 atmosphere = 33,700 Pa close enough for estimates
(the pressure requested is 1/3 atmosphere where 1 atm = 760 mm Hg)
Which acid-base chemical reaction is irreversible?(1 point)
weak acid added to water
strong acid added to water
water on its own
weak base added to water
An irreversible reaction is a reaction that tends to completion. When a strong acid added to water, the reaction is irreversible.
In chemistry, a reaction may be reversible or irreversible. In a reversible reaction, the reaction could move forward or backwards. An irreversible reaction only tends towards completion. It doesn't goes in the reverse direction.
When a weak acid or base is added to water, the reaction is reversible because the substance does not ionize to a large extent in water and the equilibrium position may lie towards the far left. However, a strong acid or base achieves 100% ionization in water hence the reaction is irreversible.
Therefore, when a strong acid added to water, the reaction is irreversible.

A 2.80 kg mass is dropped from a
height of 4.50 m. Find its kinetic
energy (KE) when it is 3.00 m
above the ground.
Answer:
41.16J
Explanation:
m =2.8 kg
h1 = 4.5 m
h2 = 3 m
PE at top = mgh1= 4.5mg
PE at 3 m = mgh2= 3mg
energy is conserved los in PE = gain in KE
KE at 3 m above the ground
= mg(4.5 - 3) J
= 2.8 kg*9.8m/s^2*1.5 m
= 41.16 joules
Answer: 42 m/s
Explanation:
m=2.8 kg , V1=0 m/s , h1=4.5 m , h2=3 m , V2=? m/s
E1 = E2 >>> K1 + U1 = K2 + U2
Kinetic Energy (KE) = K = [tex]\frac{1}{2}[/tex] m [tex]V^{2}[/tex] Potential Energy (PE) = U = mgh
[tex]\frac{1}{2}[/tex] m [tex]V1^{2}[/tex] + mg[tex]h_{1}[/tex] = K2 + mg[tex]h_{2}[/tex] >>> V1=0 >> K1=0 >>> K2 = -mgΔh
K2 = 2.8 kg × 10 m/s2 × 1.5 m = 42 m/s
