help with the number 2 question​

Explanation:

One example of how the big bang could have been the birth of the universe is the expansion of it... (Expand on it) (It says in your own words)

Answer:

Experiment

Materials needed

Stop watch, a small stone, a big stone, a balance.

Procedure

Measure the mass of the two stones.

Hold the two stones about 5m above the ground level.

Drop the stones simultaneously.

Record the time taken for the stones to strike the ground.

Repeat the procedure with different masses of objects at the same height.

Observation, it will be observed that, all the objects dropped from the same height strike the ground at the same time interval.

Conclusion; a falling object doesn't depend on mass

Explanation:

½mv²=mgh

g=½(V²/h)

When an object is held at a height, it posses gravitational potential energy which is mgh, where m= mass, h=height, g=acceleration due gravity

When the object is dropped, the potential energy will be converted to kinetic energy which is ½mv², where V=velocity at which the object moves.

V=∆h/t, ∆h is change in height with respect to time.

½mv²=mgh

Mass cancel out,

g=v²/2h

This implies that g does not depend or is not affected by mass. Hence heavy object and light object will reach the ground at the same time when dropped from the same height. When air resistance is negligible.

Answer:

the correct answer is

"SH"

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

-Insecurity

-Poverty

Answer:

9800 J

Explanation:

P.E = mgh

P.E = (10.0)(9.8)(100) = 9800 J

Your answer is in the attachment . Hope this helps.

Answer:

49.050 KW

Explanation:

work done = PE

= mgh

=5000×9.81×10

=490500J

power = workdone/Time taken

= 490500/10

= 49050 watts

= 49.050kW

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.

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.

Answer:

Potassium and iodine

Explanation: I took the quick check

Answer:

D. 16 Kgm/s

Explanation:

Let the momentum of the two balls be A and B respectively.

Momentum A = 16 kgm/s

Momentum B = 0 kgm/s (since the ball is at rest).

Total momentum = A + B

Total momentum = 16 + 0

Total momentum = 16 Kgm/s

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

Momentum = mass * velocity

Using third equation of kinematics

[tex]\\ \rm\longmapsto v^2=u^2+2as[/tex]

[tex]\\ \rm\longmapsto v^2=0^2+2(0.5)(1.6)[/tex]

[tex]\\ \rm\longmapsto v^2=1.6[/tex]

[tex]\\ \rm\longmapsto v=\sqrt{1.6}[/tex]

[tex]\\ \rm\longmapsto v=0.4m/s[/tex]

Now using 1st equation of motion

[tex]\\ \rm\longmapsto v=u+at[/tex]

[tex]\\ \rm\longmapsto t=v-u/a[/tex]

[tex]\\ \rm\longmapsto t=\dfrac{0.4-0}{0.5}[/tex]

[tex]\\ \rm\longmapsto t=\dfrac{4}{5}[/tex]

Explanation:

Acceleration is defined as the rate of change of velocity.

Acceleration = (Change in velocity) / time taken

Acceleration = (Final velocity - initial velocity) / time

As the object velocity changes by the same amount in each second, it means the acceleration is constant.

6686.6 m

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]
